I agree with Thornbeck; so cool to see things come together.
As to the restoration, if you have two overlaps due to using two pieces, you would effectively make the diameter of the drum slightly larger. If the head was tight before it will be tighter still now. If that is the case you may opt to notch one or both of the overlaps where the head sits on the drum. On the other hand it may be just fine as is.
On another note, if anyone was interested in Abalone wrap, there was a gentleman selling a large DW kit in that wrap a couple of months ago. I believe it was a 22-8-10-12-14-16. The wrap was cracked and split so part of the deal was rolls of abalone to re-wrap the kit. I nearly bought the kit as those are great rental sizes but I could not use the wrap as it is not neutral enough for a rental kit. If anyone is interested I'll see if I can find the link to the seller. The kit was taken off eBay as the price was not going high enough for him.
