Thanks, Mike. got some other advice that said with the quartersawn blank, it might be a little weak through the wrist of the grip, but a dowel or tenon installed in this area would tie the butt to the foregripstrong enough o alleviate any worries of cracking behind the action. Another guy said a thumbhole could cause hold problems, actually he's a friend of mine, but I barely touch the grip when shooting anyway, just laying my thumb on top or to the right side a little with my fingertip against the grip. Will build a practice blank to play with and maybe try some fancy sculpturing around the grip area to fit my style. Was thinking of getting some long bolts to screw into the action holes and put my digital protractor on to measure the angles, but, like you suggested, fitting a block to the front to gage the angle would be simple. Could even fit a block to the stock to make it as thick as the blank, then clamp 2 more blocks and drill through all. Then could clamp the outer blocks to the blank and presto. instant angle gages.If I get enough ideas, I might even be able to make something functional AND good looking! Thanks!
