I have made 2 stocks and have ABSOLUTELY no plans to EVER make another!!!!! I made one for my dads Model 12 Trap, bowled out to his facial dimensions, in a deep black grained American Walnut trunk a friend of ours cured for just such cause, who built stocks and was my mentor for said project.
I built one for myself for a model 12 I own and I built it with a full Monte Carlo Rollover and right hand cast off so it fit just me. NEVER AGAIN!!!!!!!! no wonder I have corpol tunnel now!!!!!! LOL!!!! They are a piece of work to sit back and admire when you are finally done and can say "I" did that and no one else and there is not another one of its kind!!!! I did the checkering on them and went with 25 LPI and it is REALLY time consuming and eye straining.
Good looking work and you will really enjoy it as will your son!!!
