I use a couple coats of die spacer over the modified abutment, wax it with my normal wax and cast it with the rest. If it's alittle tight on the abutment you can rubber wheel the shiny spots on the abutment until it seats. Easier than reaming. Dont forget to run an inverted cone bur around the inside tip of the coping. That's aways a catch point. If it's a skinny stone die then expand the casting for sure!
