make another, this time try to "petrify" the wood.
Get a mason jar and a brake bleeder pump, drill a hole in the mason jar lid, secure vacuum pump to suck the air out of the jar.
You'll need wood hardener, torch your wood and fine sand before, down to 800 grit minimum.
You can add dye or stains to get a color you like or go clear.
Put your parts to the call inside the jar, completely cover the wood with your hardener.
Secure lid, pump out the air, minimum 3 days in.
You'll replace the moisture in the wood with the hardener.
Fine sand and assemble your call, I like a turners finish for final coat, very thinly apply and fine sand, Amazon has extra fine sand paper to like 3,000 grit, and down to microns for high polish.
A lot of work but you'll find the tune you like. Very funn transforming the wood to something that will last forever!
