Wowzers, that's nice! I have a Ruger K1022T that came with a laminated stock. I have a Hogue overmolded thumbhole stock on it now, and need to figure out the comb height. I have a walnut plank with some stellar figure that I'll eventually draft into use. I hadn't thought about engine-turning the stainless parts; that's a nice bit you've done there, as well. Checkering is too fiddly for these old hands, but a basket weave I could probably accomplish. Well done!
