I started with a Phase II piston type and didn't care for the feel when tightening the tool holder down so I sold that and bought the wedge type. Much better feel to it. That being said, I have a friend who did just the opposite. Bought the wedge style, didn't like the feel, so he bought the piston style and is one happy camper. My very first QCTP was for my HF 9x20 lathe. It was a Harbor Freight QCTP and the fit and finish were equivalent to a Phase II at the time. It worked very well for me. I'm not sure if the quality of the HF QCTP has changed since it's been years since I had the 9x20 lathe.

GREAT!! I like the price but what does he mean by machine to fit? Jerry. RE: BXA QCTP - EdK - 03-08-2012 John, That's a good idea to mill the large insert tool holders to fit right on the tool post. The tool holders didn't warp when you heated them? Ed RE: BXA QCTP - EdK - 03-08-2012 (03-08-2012, 05:55 PM)ETC57 Wrote: GREAT!! Jerry, He's talking about the T-nut that fits into the compound. All (most?) QCTP come with a blank piece of steel that you have to machine to fit your compound.

A QCTP is on my short list. Jerry. RE: BXA QCTP - DaveH - 03-08-2012 John, That is a clever idea to use large insert holders. (With regard the heating you just like to set fire to things ) That parting off tool looks good.

Parting scares the bajeebas(?) out of me. I like your version of parting tool. I may have to watch ebay for a large insert parting tool to modify like you did. Ed |
