I was polishing a barrel I just finished up chambering this morning and was thinking what a pain in the ass this was then it hit me. Work smarter not harder! I put a 1/2 cratex stick (fine) in a spare tool holder set the speed to780 rpm, ran the saddle up to the muzzle touched off on the barrel and then engaged the half nut did three passes added 2k on each pass for a total of 3 passes. This took all of 5 minutes at the most. I then hit with a little break cleaner and done. This is with only a fine cratex stick with a extra fine stick which I didn’t have it would have been a lot more shiny. No mess to deal with or grit on the bed and ways.
