I was thinking about perfecting the rest and then looking at making some for sale. I teach HS machining and we could always use the funds generated to go back into the program for more stock/supplies.
Next might be the prototype of a front only rest. Seems to me that would be what most shooters will want. The purpose of this one was that I want to see if I can lock a gun into it and take the human element out of the shooting. Basically find out how accurate the gun can really be. When I get the setup right, I want to be able to stand to the side of the gun and fire 5 shots to see what kind of a group a particular gun/ammo is capable of without ever shouldering the weapon.
