Beyond the Clamps: Wrapping the Summer Bend for a Winter Reveal

We have reached Day 13 of Drum December. Using my innovative dry-bend technique and the disciplined 6-clamp method for freehand organic formation, the drum frames are now set. They have been glued and secured into their unique shapes and sizesโ€”now, we must give them the gift of time.

The Art of the Cure

In the heat of the summer, I prefer to hang the clamped frames in the maple tree at the Love Art By Po studio. Iโ€™ve found that the blazing summer sun and a hot woodshop can be too aggressive; the glue and wood need to work their magic at their own pace. This stage cannot be rushed.

Whether they are hanging in the cool shade of a tree or resting in my humidity-controlled studio, the environment must be just right. To ensure the wood “remembers” its new shape without stress, I maintain these optimal conditions:

  • Temperature Range: 18โ€“27ยฐC (65โ€“80ยฐF)
  • Humidity: 55%
  • Lighting: Reduced UV exposure with dappled, indirect sunlight

More Than Craft: The Living Drum

Once dry, the frames move into my controlled environment for about 30 days. But this isn’t just storageโ€”it is an introduction. I bring them into a living space filled with family conversation, singing, and music. I introduce them to their “sister drums” by playing the finished drums that surround them.

Some might think of drum making as simple carpentry, like crafting a coffee table, but the wood tells a different story. If you do not acknowledge their living nature, they rebel. For years, I heard stories of drums as family members who “talk” in their own ways. I never truly comprehended how that was possible until I began making them myself. Now, I know the truth: Drum making, most assuredly, becomes LIFE.

The Pivot: Moving to Real-Time

Today is December 21, 2025. Our summer-bent frames have dried, been unclamped, and are fully conditioned to the spirit of my studio. Starting tomorrow, Day 14, we leave the archives behind and move into real-time.

We are officially on a countdown to New Yearโ€™s Eve. To drum in 2026 with a newly finished piece, I must have the rawhide strung by December 27. Rawhide requires three days to dry in perfect conditions, and with the shifting winter weather outside my stringing studio, this will be a true nail-biter.

Nature will do as Nature does, and the drum is a part of that natural world. Join me tomorrow for Day 14 as we step into the workshop to begin the sanding and finishing.

See you in the studio!

See you tomorrow for Day 14!

Drum December Day 12 – How to Make a Drum Frame Using 6 Clamps

Close-up of several blue C-clamps tightly securing a glued joint on a wooden drum frame using the 6-clamp method, Day 12 tutorial by Portia Po Chapman.
Mastering the “6 Clamp Method” to ensure a secure, even bond on the dry-bent drum frame.

Drum December Day 12: Mastering the 6-Clamp Method

Welcome to Day 12 of Drum December! Today is the day we tackle dry-bending and clamping head-on. In this tutorial, youโ€™ll learn the vital “what-to-dos” (and the painful “what-not-to-dos”) of securing your frame.

Clamping hardwood is a bit like attending your grandmotherโ€™s third wedding and being asked to dance by a gentleman who took lessons from Chubby Checker. Just like a dancer from the ’60s, the wood keeps trying to “Twist.” By following my innovative 6-Clamp Method, youโ€™ll have no problem taking the lead in this clamping dance.


The Anatomy of the Dance: Twist and Circularity

When making drum frames, there are two primary style considerations you must face:

  1. The Twist: How much natural “sport” or torsion your finished frame will carry.
  2. The Shape: How perfectly circular or organic you want your finished drum to be.

Both of these decisions are finalized during the clamping stage. This is exactly why I developed the 6-Clamp Methodโ€”to give the maker total control over the woodโ€™s final expression.

Avoiding the Tangled Clamp: The Staggering Method

In Day 11, I explained how the shape changes depending on which end overlaps on the outside. Today, we focus on the direction of the clamps.

Because you are using six heavy-duty C-clamps in very close proximity, the handles can easily get stuck against each other. It can be a deeply frustrating process! Below is a video of my own experience trying to turn clamp handles that weren’t staggered. If you find it painful to watch, just imagine being the one trying to turn them under pressure!

To solve this, we stagger the clampsโ€”top and bottomโ€”in a disciplined sequence. This allows us to intricately pull the seam together while “reading” the bend and twist of the frame.

The 6-Clamp Sequence: A Step-by-Step Guide

I have created this incremental schematic to show you the exact order of operations. Note how each clamp is placed to manage the tension of the 3″ to 5″ glued seam:

  1. Clamp #1: Placed on the top, dead-center of the seam.
  2. Clamp #2: Placed directly beneath the first, but facing the opposite direction.
  3. Clamps #3 & #4: Placed on the side of the center clamps closest to the inner board end.
  4. Clamps #5 & #6: Placed on the remaining opposite side.

Shaping with Baffles: Controlling the Curve

In the schematic video above, I omitted the cutoff baffles (the hardwood blocks that protect your frame) for clarity. However, you must use them!

The size of the baffle on the inside of the frame actually alters the drum’s final shape.

  • The Standard: I typically use a 1″ x 3″ piece of oak.
  • The Adjustment: If you want to flatten a side or create an egg-shaped drum, you do this by widening the inner baffle. The wider the baffle, the flatter that section of the frame becomes.
  • The Rule of Thumb: I generally use a 1″ wide piece on the inside and a 2″ wide piece on the outside, adjusting the spacing as I feel the wood react.

The Goldilocks Grip: Just Enough Pressure

By alternating your clamps, you aren’t just preventing a handle jamโ€”you are managing the twist. When the first clamp goes on, you can adjust the shift and slide of the frame. The second clamp adds stability, and clamps three through six do the heavy lifting.

Tighten them as firmly as your hand can turnโ€”no need for tools. You are looking for the glue to “squeeze out” evenly along the seam. Be careful not to over-tighten! If you squeeze out too much glue, youโ€™ll create a “starved” joint. This results in a fragile frame that may snap when the powerful tension of the rawhide eventually pulls it into its final form.

Looking Ahead

If you think a tree has a long memory, just wait until you see the nature of rawhide. Keep following the Drum December series to see how we work with animal skins in the coming days.

Even if you never pick up a clamp yourself, I hope youโ€™ve learned how to straighten out “The Twist.” Just start in the middle of the floor and lead your partnerโ€”side-stepping and swaying until the song is done and you both become one with the true drumbeat of life.

See you tomorrow for Day 13!

Drum December Day 11 – How to Clamp a Drum Frame

Day 11: Applying high-pressure clamps to the glued frame is the final step to ensuring a rattle-free, resonant instrument.

Drum December Day 11: Mastering the Compression and Clamping of Your Drum Frame

Welcome back to Drum December! Today, we are diving into one of the most transformative stages of the process: using my innovative dry-bending technique to compress and clamp the drum frame. This method is born from my preference for non-polyurethane glues, which we explored in our Day 10 tutorial.

By utilizing sun-steamed wood that has been “trained” during the pre-bending phase, we gain incredible creative flexibility when it comes time for the final clamp. If you missed the early stages of this journey, you can catch up on Day 5 and Drum December Begins to see how we prepare the wood to be shaped.


The “impossible” C-Shape

After trimming the frame on Day 9, you are left with a piece of wood that has a massive 16-inch gap between the ends. It looks like a giant letter “C,” and honestly, it looks impossible to close. But this is where the magic happens.

Choosing Your Bending Method

There are two primary ways to bring those ends together:

  1. Mechanical Bending: Using a dedicated jig or form to force the wood into a circle.
  2. Freehand Bending: Bending the wood by hand and clamping the ends using only hardwood cutoffs as buffers.

I personally prefer the freehand dry-bending method. My clients love it because it results in a more organic, natural shape and a superior sound.

The Critical Decision: Inside or Outside?

Before you apply a single clamp, you must decide which end of the wood will overlap on the outside. This might seem minor, but it is vital:

  • The choice of which end goes on the outside literally alters the final shape and resonance of the drum.
  • The inner end experiences a much tighter curve than the outer end.
  • Even with identical ends, swapping the overlap order can create a completely different hoop shape.

The Miracle of Elasticity

The most remarkable part of this technique is the elastic response of the hardwood. Because of the sun-steaming and pre-bending, the wood becomes incredibly flexible. In my demonstrations, you can see a cherry wood frame compressed over 16 inches with ease.

I view myself as a facilitator for the tree. When you encourage the wood to bend naturally, it “sings”. If you force it, the wood rebels, cracks, and the sound becomes muted. A drum makerโ€™s job is to unlock that voice, not silence it.

Letting the Tree Sing: The Philosophy of the Bend

It is truly a remarkable thing to witness, and I often wonder why this method isn’t the gold standard. When we dry-bend, the results are simply superior to clamping freshly steamed woodโ€”especially when crafting those challenging, small-radius frames.

Using this technique feels less like “construction” and more like an act of listening. In the forest, trees are designed to dance; their limbs are built to bend when the wind caresses them. In my workshop, I see myself as a facilitator of that natural expression.

When you allow the wood to bend on its own terms, it sings. When you force it, the wood rebels; it cracks, it groans, and its spirit becomes muted. As a drum maker, my calling is to encourage the drum to find its voice, not to silence it through force.

The “Vet Visit”: Understanding Woodโ€™s Resistance

Once the wood has agreed to take its shape and the decisions of Day 10 are behind us, we move into the physical intensity of the clamping stage.

Even a willing tree has its limits. Wood has a memory and a will of its own, and it behaves much like a dog on the way to the veterinarian. The pup is perfectly calm in the car until you turn that final cornerโ€”the moment she realizes whatโ€™s happening, she “flips out.”

The drum frame does the same. It will rest quietly in your hands until the moment you bring the glue bottle near. It is the strangest, most miraculous sensation: you can feel the frame shift from a gentle yield to a spirited push-back against the compression. To navigate this, you need a sturdy vice and quick clamps within arm’s reachโ€”or a very strong, steady assistant to help you hold the tension.

The Trick of the Trade: Precision and Protection

Because the wood is alive and moving, using C-clamps is a high-stakes, time-sensitive dance. The second the clamp touches the wood, everything wants to slide and shift. I used to panic during this stage, but I eventually learned the secret: The One-Inch Rule.

  • Keep it Tight: Ensure your C-clamp is open less than an inch. This allows you to turn the handle and lock it down before the wood has a chance to escape.
  • The Safety Net: If you canโ€™t turn the handle fast enough, snap a couple of quick clamps on either side of the joint. They will hold the frame long enough for you to seat your heavy-duty C-clamps properly.
  • Honor the Surface: Never let metal touch the frame directly. A C-clamp is a powerful tool that can easily dent the wood. Always use hardwood cutoffs as a barrier between the clamp and the frame. Even with light-duty clamps, these barriers are essential for protecting the integrity of the wood.

In the video below, you can see this “C-clamp dance” in action as we bring the ends together for the final time.

Pro-Tips for Successful ClampingA Summary for You to Remember

Keep these clamping tips in mind:

  • Speed is Key: If using C-clamps, keep them open less than an inch so you can tighten the handle quickly before the wood shifts.
  • Use Backups: If you can’t move fast enough, use quick clamps on either side of the joint to hold the position while you set your C-clamps.
  • Always Use Barriers: Never put a C-clamp directly on the frame; it will dent the wood. Always use hardwood cutoffs as a barrier between the clamp and the drum.
  • Clamping Numbers: Use at least six clamps to secure the joint while it dries.

Barrier Dimensions: Use wood cutoffs approximately 1″ x 3″ for the inside of the frame, and 2″ x 3″ for the outside.

Whatโ€™s Next? Tomorrow, on Day 12, Iโ€™ll show you exactly how to arrange those six clamps so they donโ€™t get tangled or interfere with the curve of the frame. Itโ€™s a bit like a puzzle, but Iโ€™ll walk you through it!

Drum December Day 10 | How to Glue Before Clamping Drum Frame

Drum December Day 10 – Po Glues the White Drum Frame Before Clamping the Dry-Bend

Choosing the Right Glue for Handcrafted Drum Frames | Drum December Day 10

At the Love Art by Po studio in Kingston, I believe that building a professional-grade drum frame is as much about the type of glue as it is the technique used to apply it.

Different moisture levels in wood require different chemical bonds. Whether you are working with freshly steamed “green” wood or seasoned dry wood, choosing the wrong adhesive can compromise the sound of your instrument. In todayโ€™s update, Iโ€™ll explain how to pick the right glue at your local hardware store to ensure a lifetime of pure sound.


The Challenge: Gluing Damp vs. Dry Wood

The first hurdle every drum maker faces is moisture. If you are bending steamed red oak, the wood is naturally damp.

Early in my practice as an installation artist, I treated drum frames like standard carpentryโ€”LePage Pro Carpenterโ€™s Glue. However, standard wood glue and damp, steamed wood do not mix. I would return to my shop table the next morning to find the joint “slimy” and uncured on the inside.

The Polyurethane Solution

To glue damp wood effectively, you need a moisture-activated adhesive like Original Gorilla Glue. This polyurethane glue uses the moisture in the wood to “activate” the bond. It bonds damp frames like a dream, but it comes with a significant trade-off: The Foam.


The Science of Sound: Why “Foaming” Glue Causes Rattle

If you want a pure, resonance-free tone, you must understand how glue affects vibration. Polyurethane glue expands into a foam, creating tiny air pockets within the joint.

Are Drum Frames Meant to Rattle?

  • The Rattle: If you enjoy a “smooth rattle” or mechanical reverberation, foaming glue is your best friend.
  • The Pure Tone: If you want a clean strike, never use foaming glue. The drum frame produces sound just as much as the rawhide. If your glue joint contains air pockets, the vibration of the drum strike can cause a “seam rattle” deep within the wood.

How to avoid the rattle:

  1. Glue the frame only when the wood is fully dry.
  2. Use a non-foaming moisture-resistant glue like Gorilla Glue Clear. (Note: “Non-foaming” glues can be slippery, making clamping a damp frame more difficult.)

Three Steps to a Rattle-Free Steamed Frame

If you are new to drum making, remember that hitting a drum with “enthusiastic force” will eventually shake loose any weak or brittle bonds. To ensure your steamed frame remains silent and solid, follow these three steps:

  1. Cooling Time: Let the wood cool until it is no longer steaming, but is still slightly damp before applying glue.
  2. Even Spread: Use a non-foaming polyurethane glue spread evenly across the entire joint.
  3. Pressure: Use 6+ C-clamps, applied two at a time on opposite sides to ensure even compression.

Innovating with Dry Wood Bending

For my premium drums, I prefer to glue the wood when it is fully dry. This produces a beautiful, rattle-free instrument. However, dry hardwood doesn’t like to bendโ€”it behaves like a floor plank!

To solve this, I developed a proprietary dry-bending technique. The wood is pre-bent and shaped before the glue is ever applied. You can see the foundation of this technique in my previous posts: Day 5, Day 7, and Day 8.

My Go-To Choice: Titebond III

For dry, single-layer frames, I recommend Titebond III Ultimate.

  • Why? It offers a longer working time, becomes “tacky” quickly for better clamping, and is rated for both interior and exterior use.
  • The Secret: Let the wood and glue “perform their magic” for at least 24 hours before sanding or knocking the frame.

The “Drum Making Golden Rule”

Frame drums are built for lifeโ€”they go from drizzling rain at a community circle to the dry heat of a bonfire. Because they are exposed to moisture, heat, and travel, your glue must be waterproof.

The Golden Rule:

No matter the purpose of the drum, ALWAYS use a high-strength, waterproof glue that produces zero (or nearly zero) bubbles.


Coming Tomorrow: Join me for Drum December Day 11, where Iโ€™ll share a deep-dive tutorial on Professional Clamping. I’ll show you the “tricks of the trade” to ensure your frame is perfectly circular and structurally sound.


See you tomorrow!

Kingston Artist, Portia “Po” Chapman trims the white oak drum frame to size at her studio.

On day 8, my trusty assistant compressed the dry bent oak to the size that I wanted for the finished drum to become. As he held it in place, I marked the board with a pencil. Day 9, also marks the mid stage of drum frame creation.

Once we cut off the white oak at yesterday’s pencil markings, we will see the drum frame coming into its drum shape for the first time. I have a smaller trim miter saw, but I prefer using my 12″ chop saw with a trimming tooth blade installed. The larger blade alleviates the fiddliness of cutting the large hoop with a small blade.


Oh, and this trim will remove the breakage that we found on day 6. Phew!

Come back tomorrow, Day 10, when we move on to our next stage of drum frame creation: gluing and dry-bending. The next couple days are going to be exciting; we are on the homeward stretch now.

Come back tomorrow for Day 10 – when we apply the glue. There are 4 types of glue that we can use, I will explain the options on Day 10.

On Day 8 of Drum December, Po’s assistant compresses the bent oak while Po marks the board where she will cut it on Day 9.

Thank you for watching along as we engage on this drum making adventure. This is the first time that I have made a white oak drum frame and as you can see, it has been an adventure.

On Day 8 of Drum December, my assistant and I prepare the steam-bent white oak which is to be cut off in order to create my preferred drum diameter. The reason I mark the wood this way is because the best sounding drums have the least glue. So by marking it with both ends overlapping, I can judge how large the completed joint will become. I aim for a 2″ drum frame joint when the drum is complete.

For more information about Love Art by Po drums see here.

The Art of Compression Without Snapping the Frame

The process of compression without snapping the frame is exceptionally nuanced and requires much attention. This is the reason why I prefer dry-bending the final bend. The stunning personality of every piece of milled and bent timbre is felt as the compression reaches its limit. I have tried mechanical bending methods but those methods remove the connection with the fibres, and this process needs to be gentle and understanding.

Hugging Drums is Like Hugging Trees

Just because a tree is cut down and made into lumber, it never stops being a tree. I grew up listening to trees. For 18 years of my life, they sheltered me, comforted me, and taught me ancient lessons of beauty and strength. I met my ancestors as they stooped down, inviting me to sing as their branches drummed a beat for me to follow. In my second year of my BFA, the apple tree, that I used to climb as a child, died and began falling to the ground. In a way, I felt to blame for its loss of health.

You see, I left it in the field when I went away to University. So for my first large sculpture installation, I gave it back its voice by sculpting it back to its life giving form – even with birds nests and robin eggs. I could once agin hear it whisper. In the spring, when I returned to the field, the apple tree, at the very top, was growing leaves reaching to the sky. Today, as I make frame drums, it is my way of giving back to the trees – to hear their voices sing again. For me, I feel blessed to be a drum maker. It is a calling. It is LIFE! When shaping drum frames, I hug them just like I hug trees still able to stand. Every drum frame is realized out of love and respect.

To read more about Indigenous relationships with trees, follow this link. But please come back.

Gentleness Guided the Bend

For the compression, you will notice in the video, my assistant has rested the white oak on his lap. By doing so, he makes full contact with both sides of the new drum frame shape. He can feel the oak tighten and relax. He makes it look so easy after many years of woodworking, but this critical step truly requires inner stillness. After all, I learned to hug trees because of him. As he bends it, he can hear the oak say when it has coiled enough. Just as it reaches its chosen limit, I can sense it too.

This white oak, has required understanding more than the other hardwoods. But, when it reached its bend limit, instead of screaming out, it gave a relaxed sigh of relief, like it said: “Finally back home.”

Marking the Board

Due to the length of the video, it is unclear where I marked the piece. In this case, I marked it in two locations. Often, I do one continuous mark across both edges. Again, this is not a science. I wish that I could give a clear instruction, but it really is again about… Knowing the right spot(s).

To read more about my art practise, please click this link:

When I set out to write this post about this seemingly simple bend and mark, it was not my intention to share the spiritual, soulful relationship of bending drum frames. I guess, the ancestors thought that it was a good time to remind us that drum frames and drums are just as much part of this life as they were as trees. Please know that when you buy (adopt) one of the drums that I make, your drum has been nurtured into existence with care.

Come back tomorrow for Day 9 – the painful moment of cutting the frame to size.

See you tomorrow!

Drum December Day 7 โ€” Releasing the Clamps on the White Oak Frame

Portia โ€œPoโ€ Chapman carefully releasing three blue clamps from a bent white oak drum frame during Day 7 of Drum December. The frame gently opens as Po tests the success of the first bend.
Day 7: Po releases the clamps on the white oak drum frame โ€” the moment of truth in the Drum December bending sequence.

Drum December, Day 7’s update brings you right into one of my favourite moments in the drum-making process โ€” releasing the clamps after a full overnight bend (in this case, it took 48 hours to dry). Thereโ€™s always a little suspense in the air: did the frame hold its curve? Did yesterdayโ€™s small white oak split stay contained? OR… Would I just get slapped in the face?

If youโ€™re new to Drum December, Iโ€™m Portia โ€œPoโ€ Chapman โ€” the artist behind these handmade drum frames. You can learn more about my artwork and workshops on my About & Contact page.

Checking the Strength and Integrity of the First Bend

With slow hands and hopeful curiosity, I began removing the clamps one by one. The wood felt settled and responsive, and despite yesterdayโ€™s unfortunate split, the frame held together beautifully. The bend set cleanly and the character of the wood showed itself the way only white oak could; it was strong and unpredictable.

This is one of the reasons I love teaching you about the process of drum-making. Every piece of wood has its own story; some bend effortlessly, while others challenge you and reveal their limits as you work. Day 7 reminds me that, some days, drum frame making is as much about bravery as it is about skill.

Come back tomorrow when we will compress the white oak to the size of drum that I want and proceed to draw the cut marks for length.

See you tomorrow!

Drum December Day 6 โ€” A Small Split, But a Successful First Bend

A close-up of Portia โ€œPoโ€ Chapman examining a freshly bent white oak drum frame outdoors, pointing to a small split formed during the tight first bend, with bright flowers and summer greenery behind her.
Day 6: A small white oak split appears after the first bend โ€” an expected part of pushing hardwood to its limits.

Today marks the moment of truth for the first bend of the white oak drum frame. After spending the night under clamps, the wood finally revealed how it responded to yesterdayโ€™s bending session โ€” and as always, the material had a story to tell.

If youโ€™re new here and want to learn more about who I am and the work I do, you can visit my About & Contact page.

When I brought the frame into the studio this morning, the very first thing I did was check the inside curve. And there it was:
a small split along the tightest part of the bend.

For many people, that might feel alarming. But for me, this isnโ€™t unusual at all โ€” especially with a dense hardwood like white oak. Pushing any wood to the minimum bend radius it can tolerate means youโ€™re working right at the threshold where the fibres must stretch, compress, and adapt. Sometimes, a small split appears as part of that process.


What a Split Really Means in Drum Making

A split doesnโ€™t automatically mean failure.

Itโ€™s a diagnostic clue.

It tells me:

  • how far the wood was willing to travel,
  • how much internal tension remains in the frame,
  • and whether the second bend โ€” the glued dry-bend โ€” will seat properly.

In this case, the split is shallow and controlled. That tells me the clamps did exactly what they were supposed to do:
prevent the fibres from opening too far while still allowing the bend to hold.

This is why clamp placement is a true art form in drum making. You donโ€™t just tighten clamps to tighten clamps. You tighten them in anticipation of how the wood is likely to react.

White oak is expressive โ€” and today, it expressed itself in a way that still sets us up for a strong final frame. As well, the location of the minor breakage will be cut off before gluing the final bend. I don’t sweat these things now, but when I first started bending drum frames, I was totally panicked when the first breakage happened. It was a learning experience – that is for sure!


Reading Tension, Relaxation, and โ€œFeelโ€

Every wood species responds differently during the first bend.
White oak? Well…It hums with a very particular kind of density.

When I picked up the bent frame today, I could feel subtle tension still living inside the curve. Thatโ€™s not unexpected โ€” in fact, with white oak, itโ€™s quite normal. White oak, unlike red oak, doesn’t particularly like being bent.

The key for Day 6 is simply evaluating:

  • Did the bend hold its overall shape?
  • Is the curve even?
  • Is the split stable and non-progressive?
  • Does the wood want to spring open dramatically or gently?

All signs today point to a solid first bend. It was a success. PHEW!!!


Come back tomorrow, Day 7, to watch and read about the what happened when I released the clamps.

The next step โ€” which comes tomorrow โ€” is the careful release of the clamps. Thatโ€™s where I discover how much reflex the wood has stored and whether it settles into the intended diameter or pushes back aggressively.

For now, the job is simply to observe, interpret, and prepare.

White oak may be challenging, but todayโ€™s results show that this drum frame is very much on track.

See you tomorrow for Day 7 of Drum December!

Drum December โ€“ Day 5: Time for Clamping

Close-up of hands holding the softened red oak board after sun-steaming, preparing the ends for clamping during Poโ€™s frame drum-making process on Drum December Day 5.
Po prepares the sun-steamed red oak board for its first clamp โ€” the moment the drumโ€™s circular form begins.

Today marks a major turning point in Poโ€™s sun-steamed red oak experiment โ€” the moment when softened hardwood, warm from the solar tubes, is guided into its first held shape. After days of heating, coaxing, and patiently encouraging the wood fibres to relax, itโ€™s finally time for the clamp.

Freehand bending is never a one-person job. With red oak especially โ€” two sets of hands are essential. One pair holds the ends together, and the other manages the clamps with steady confidence.

As the camera rolls, Poโ€™s assistant lifts one end of the oak over the other. You can see immediately that the top end doesnโ€™t lie flat; instead, it sticks out stubbornly, like a child refusing bedtime. This is normal. In every bend, no matter the length, one end refuses to behave. The wood always tries to return to straightness โ€” its original memory.

To protect the tender, freshly steamed wood, Po uses two small oak offcuts as buffers. The cut-offs keep the clamp from denting the softened wood, which is especially vulnerable before it dries.

The First Clamp: Where Courage Meets Making

Po tightens the lower piece first, then holds the top piece and slowly turns the clamp. With each rotation, the ends of the red oak pull closer together. This is the first of two clamping stages in Poโ€™s innovative dry-bending technique โ€” a method she has refined through experimentation, intuition, and respect for the material.

This first loop must dry with the clamps on for about two days.
Only then will the wood be ready to release, be cut to size, glued, and clamped again into its final drum frame shape.

What the video doesnโ€™t show is just how lively the wood can be. Even at this stage, red oak is strong and springy. If it suddenly opens, the clamp can fly across the room โ€” a heavy steel reminder that wood is a living material. Some drum makers use ratcheting straps to control this, but Po avoids this method. The hooks and pressure points donโ€™t sit flush, and can scar the damp wood just before it snaps back.

Instead, Po trusts the method shown here โ€” a method that gives her control, precision, and the markings she demands from her handcrafted drum frames.

Freehand bending sun-steamed wood may look simple, but it takes courage, strength, intuition, and sometimesโ€ฆ a little prayer.

And today, with hands steady and clamps in place, Po brings her drum loop one step closer to becoming the finished frame that will hold the heartbeat of future songs.


Check back for Day 6 to see how the bend holds โ€” and what surprises the wood reveals next.

Drum December Day 4 | Finding the Nerve to Bend

Po and her assistant sharing a moment of nervous laughter while preparing to bend sun-steamed white oak for a drum frame during Drum December Day 4 at Poโ€™s Kingston Art Studio.
Po and her assistant share a moment of nervous laughter.

Today, Po takes the next brave step in her sun-steaming white oak experiment โ€” the moment when softened hardwood meets human hands for its very first bend. And this time, the studio was full of laughter, nerves, and a little bit of chaos.

Preparing for the First Bend

After three days of solar steaming and fibre relaxation, the white oak was finally ready to move toward its circular drum shape. But white oak is known for being stubborn โ€” unlike red oak or cherry, which tend to cooperate more easily. This was Poโ€™s very first time attempting to bend white oak, and the air carried that charged mix of excitement and hesitation.

Because the frame pieces were long, Po called in an assistant during this stage. Today, she chose DAD.

Before the camera was rolling, Po looked at her assistant with a theatrical seriousness and joked:

โ€œIf it breaks, you can be the one to blame!
I donโ€™t want to be the one who snaps it.โ€

That set the tone.
The wood was ready.
Weโ€ฆ were getting there.

The Moment Before the Bend

As her assistant stood there, holding one end of the hot, hopefully flexible, board trying to work up the courage for the first bend, Po stepped beside her trusty assistant to offer support โ€” and then they immediately broke into laughter. She tucked herself halfway behind his arm, peeking out like someone about to watch a suspenseful scene in a movie.

The cameraperson had already begun losing patience with how long it was taking and insisted that they stop laughing and get serious. She wanted to get the shot. Then she started laughing.

This is the real life of drum frame bending at Poโ€™s Kingston Art Studio โ€” part process, part comedy, all family, ALL ART. Drum making is a beautiful, love-filled-art, and this short video illustrates the joy that cheers out with exuberance of Love Art By Po.

Nervous Laughter, Real Art

In todayโ€™s short video, you can witness the exact moment when nervous laughter gives way to determination. Po, her assistant and cameraperson take their positions, breathe through the tension, and finally begin the first coaxing bend of the white oak.

Itโ€™s only a small curve โ€” a gentle start โ€” but it marks the beginning of the transformation, from plank to drum. And as simple as it looks, this step matters: the first bend dictates how the wood will behave when the full circular frame is shaped and clamped.

A Family Moment in the Making of a Drum

What the video doesnโ€™t capture โ€” but what filled the studio โ€” is the feeling of teamwork.
Making drums in this space has always been infused with love, humour, and family togetherness. Today was no exception.

Drum-making is not simply about shaping wood at Love Art By Po;
itโ€™s about beautiful, shaping moments โ€” that make everyone stronger.

Making drums has taught Po an incredible life lesson – a circle of wood is like a circle of loved-ones, when you push on them – they get stronger as they find their harmonious tune.

Join us again for Day 5, where Po continues shaping the wood โ€” and the shared moments โ€” that make every drum a circle of strength and love.
