An assembly of ours consists of a worm mounted to a shaft. The two are held together by a roll (shear) pin. The hole diameter is .093" and the worm hub diameter is .50". Our best hammering guy retired a short time ago and the rest of the crew has trouble getting the pin inserted and pounded in. I was looking to find a way for the assemblers to open up the hole a bit (a couple of thousands would help). We use flexible hones on other items and they work well but it doesn't appear they are available for a .093" hole. The worm is hardened to 50 Rc which limits what would work and hold up. Any ideas?
