I've done the burning method......accidently and it does work,but keep an eye on it.On some drums ,because Ludwig used the 100% glue method,some of the mahogany wood may come off,and that is unavoidable in some cases.You must go VERY slow to avoid that.Sanding slowly must also be observed,as that outer ply of mahogany is very thin,compared to the much thicker poplar middle ply.
Remember,Ludwig also used a scarf joint with part of the wrap,going into the scarf joint,so,thats where the de-wrap stops.Don't try to get that last piece of wrap out of there.The seam WILL come apart,and now the shell is useless.They only stopped using that building process in 68-69,and is known as the Ludwig hump.
Lastly,unless the wrap was damaged beyond repair,there's no way I would re-wrap a 60's vintage Ludwig drum.If you don't like the color,sell them to someone who does,and buy a kit who's color you do like.
