I don't think I posted that a H10 couldn't do a good job, it just ain't the quality of my 10EE. I do my chambering on my Clausing 6913. Somebody said they couldn't get their lathe slow enough for chamber reaming? How slow do you think you need to go. I have a Grizzly 0709 lathe. It is heavy and works very well, but is awkward for me to use.
