old thread, but i will attempt an answer
i have learned a neat little trick for getting dents out of rifle stocks.
put the wood in the dishwasher,
run [dishwasher] thru a wash cycle, in the dry cycle
put your wood in , steam the wood,
take it out, let it rest/dry, then sand it smooth
this will take out dings and dents
i have heard of wrapping wood in a damp towel putting in the microwave, but i have never attempted that
NOTE...not inlaid or glued pieces.....
