I think I found my way of removing old drum wrap from a 3-ply Ludwig Shell. I got in today other 14 X 10 Ludwig Tom. This time in 3-ply. The wrap was intact and only lifting at the seem, but it had faded and at one point was covered in stickers. So I decided to make more sellable I would remove the wrap. I came up with a way of doing it which I'm sure others on this site already new how but I thought I'd share.
The seem of the wrap as I said was already lifting so Step 1 was already done for me. I then took a straight edge put it vertically across the drum about two or three inches from the edge of the seem and used a couple of those plastic clamps to hold the straight edge on. I then took my knife and scored the wrap a couple of times but not going right through the wrap. Next I Removed the straight edge, grabbed my metal dry wall/ putty knife and the heat gun. Heated up the blade then push the knife under the wrap about a inch at the top of the shell and pushed it down to the bottom breaking the bond of the glue. Then I pushed the putty knife in from the side, wiggling it a bit until it just past the line I had scribed my the box cutter. I did that all the way down. Then I just grabbed the edge of the wrap and gently pulled it up until it snapped off at the line. This way won't well if you are planning on saving the wrap which I wasn't. I would rather remove this way a little at a time then removing it in a hurry and ruining a perfect good shell.
Here are some pics of the finished Project. Pic#3 you see the poplar ply in a couple of spots. That wasn't done by me. That's factory. That was just under the wrap seem. That's also where the seem of the shell is and where the Mahogany Ply is the thinnest.
Pic#4 Is just to show you what I have to do next. People that do S$%T like this need to have there head shoved inside a bass drum while it's being played. To me there no different than people that leave classic cars to rust in a field or barn.
