I've worked on some hobbyist-level wood projects before, but I've never built a drum so I can't give much advice....other than to be aware that the thinner you go, the more the wood will warp/contort. I also know that wood is under tension in different parameters according to the grain orientation and when you relieve the tension in one spot, by cutting or lathing, you will end up with tension in a different spot. I see some wavy looking grain in that log. I'm sure it will be beautiful...but stable? -not so sure! Even, nice long-time air dried wood will move around if given a chance.

I've always believed that ply drum shells are superior to solid shells for this very reason. People will argue that the tone is much better with a solid shell...but if the solid shell is warped, then it won't sound good.

You might be better off to cut two, narrow shells from the log and make each a different thickness. Or make one with and one without re-rings. The shallower depth would likely make the wood stability better....maybe.

Thanks! I emailed Todd.

Update:

He cut it about 7 1/4 " deep and he went about 9/16" thick. He said he was afraid to go much thinner. I can always cut down if needed...

Here are some pics:

Wow. I have never seen a drum (that I was aware of) made by turning from it’s natural state. Your friend is a turner at another level! Like O-lugs said, I hope it doesn’t change its shape much as it acclimates to its new shape.

I remember that there were some snare drums that used Eames shells (ply) and some of those were very thick, so it might be an interesting sound. Again, personally, I would like to see a shallower depth because some of those really deep shell drums start to sound like parade drums to me. But your friend did some beautiful turning!

please keep us updated!

I told him to go deep because I will cut it down to desired depth once I figure it out. Not sure what depth to go?

Here is a couple more pics he just sent.

I`d be curious to see how that big knot in the wood will react over time...Especially, since it is near the edge...

Kudos to your friend!!

Cheers

Yeah...not sure. I can cut down if I have too.
