I have not thought much about it, but i would think that it would not be difficult to do. Buy a connector for all-thread (the ones that look like a nut but are 1 1/2" or 2" long. Buy one for 1/4" or 5/16". Measure the length and drill a hole in your stock (needs to be wood) just small enough to make the nut fit snug with out splitting the stock and just deep enough to have it fit flush with the bottom of the stock. Next drill an over sized hole for your elevator to an appropriate depth for adjustments. Buy a carriage bolt of the appropriate size and length. Use the head for a foot or cut the head off and put on a rubber cap. Buy a wing nut of the appropriate size to tighten against the all thread connector. drive in the all tread nut and epoxy into place, be careful not to get the epoxy into the through hole or threads. You might be able to wax up the carriage bolt ( I use shoe polish) real good and run it in to keep the epoxy away from where it should go. That just gave me another idea - drill out the stock a little over size for the carriage bolt, fill hole with epoxy (I like JB Weld) and wax up the carriage bolt. Let the epoxy set and the back out the carriage bolt. Not sure if that will work - you would have to make sure the threads were de-burred well and a generous amount of wax put on it. The plus side is you could put a larger diameter bolt in. The nut I have been talking about gets a little large in diameter so you have to be careful about not getting it so large, it will break out the sides of the stock. Carriage bolts can be bought in 5" and 6" lengths usually. I am rambling on, but maybe it will give you some ideas of your own - get the noggin goin' a little. Good Luck and Good shooting
