I'm curious as to why #8 dimple dies require drilling a #19 hole since the holes expand so much once dimpled. I've been drilling with a #20 drill to tighten up the hole slightly, but the holes are still huge once dimpled. I'm very tempted to modify my dies in the lathe to make the pilot smaller so I can drill smaller holes. I pulled one of the tank screws on my Rocket and noticed that the Czechs were cognizant of this and the dimpled holes are much tighter. Anyone besides me ever notice this?
