Trust me, this walnut is dry and stable! I have made stock/forearm sets for three 1885 Highwall type rifles, an old Stevens 94 12 gauge shotgun, an 1895 Marlin lever action and a Contender Carbine and that was mostly before the wood had dried as long as it has now. I also have some new Walnut crotch wood that has been drying only 6 months or so and I think at this point it is past the critical checking/cracking stage, at least as long as I leave it where it is for another year at least. This wood has some really nice feather grain with two pieces in particular having heavy feather figure on both sides, I have another SS project in the works and plan to use one of those pieces for that.
Cold1, any time you are ready just send me a PM and the dimensions you want it cut to, the pieces I have in mind are over 6 years dry now and about 3" thick.
