My perception is that MMC and Dorian are not an option for power checkering. Does anybody have any experience with the Hosford tool?

Thanks

No, they seem to be new; better get one before they go under like the other makers.

Michael Ullman, an ACGG member has purchased the manufacturing rights for the Doiron tool. He will be making them shortly. He now is making cutters for the MMC and the Doiron and cutters for the hand tools.

I haven't needed any tools but when I do I'll be contacting Ullman Precision

He says he will have a table full at DSC
