This looks like a nifty solution to parting tool chatter and suddenly digging in. Will your design with the dimensions on your plans work on an AXA100 Size QCTP mounted a Grizzly G0752 10 x 22 lathe? I tried their provided parting tool holder last night, very carefully adjusting the 1/8 wide x 1/2" cutoff blade I got for it, trying dead on center, and both just slightly above or below center. I was using a 3/4" dia. length of 12L14 steel, parting about 3/4" away from the chuck jaws. Running at between 90 and 150 rpm. With cutting oil. I kept having a problem of it suddenly hogging into the piece, even though I was barely feeding in. Chipped the cutter once, so I had to re-grind the end. Also tripped the shutdown on the variable speed drive when it dove in a few times. I've parted things off on my older 7x10 mini lathe successfully, so this is frustrating. I thought maybe your tool might provide a solution. I've got the cross slide gib nice and snug, and even tried tightening the compound gib very snug making it hard to turn the handle, but it is still shocking and a bit scary how much things move when it grabs like that.
I began to wonder about maybe using a rocker tool post for parting, just to get the load centered better on the compound slide. But I'd rather stick with the AXA if I can.
