That is about the idea, but that lathe has a big enough footprint on the carriage to work well with the centered toolpost. > On the Holbrook Minor I made a special casting: > https://picasaweb.google.com/108164504656404380542/Holbrook#6237477947 >128358578 There, you did the opposite offset to what I have in mind, but again the carriage has a wide enough footprint. Since most QC holders will put the tool tip someplace off the left front corner when using either face for the toolholder, I need to move the QC's anchoring bolt to the right and possibly in or out. The mount to the carriage is such that I can drill & tap that 10mm hole off-center of the carriage, and pull the tool tip back (or fwd as the situation requires) and to the right far enough to put the cutting forces inside the carriages footprint on the bed. That "having it made" gives me an idea, we have a local foundry, making huge truck tire wheel inner hubs with the spokes. I might be able to scrounge a piece of scrap from them. First stop of the day in fact. Thanks Andy. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
