I seem to remember some years ago someone had increased the through-bore of the standard 3" 3-jaw chuck, but I can't remember where and didn't find anything in my search.? It may have been toolsandmods.com, but that site appears to be defunct now.
I was using the lathe last night and the 5/8" bar stock I was using had trouble sliding through the chuck bore.? It was really tight.? How big can you go without causing issues?? I know the screws holding the back cover on are already close to the bore.
