there are a few pics away from the scarf joint that i posted including the last one. Why dampen the wood? doesn't sound like a great thing to do to a vintage drum.
Just a little patch on the edges,..the glue will not absorb the moisture and show a different shade .
All those pics are in dull light and there is so much dryrot pitting it`s hard to tell from Boston !!
It will not harm you edges !!
