I got the delrin at a place I used to work, I don't know where to find it off hand. I have lamminated walnut together with no problems, I would think other woods would work fine if your going for the multi-material look. As far as finnishing the delrin, I use a router to radius all the edges that I want, then I use a belt sander to finnish the contours, then use a couple of different grits of sand paper by hand, then I use steel wool to finnish. Leaves a pretty good finnish that pretty much matches the pachmyer grips. Hope this helps. KN
