Default Harbor Freight #42806 QCTP

Last week I was turning some small diameter stock, I want to use some small 1/4“ tool I had, the tool holders I have, would not hold tools that small. I worked around that with some serious shimming, but never felt secure about it.

Today, I happen on a Harbor Freight #42806, QCTP kit, it list for about $100 and my total cost was less than $30. The kit is designed for a mini lathe and is optimized for 1/4” and 5/16” tooling. I spent a good part of the afternoon, adapting it to my current lathe, a Jet 14 x 40. After I finished it up, I set it up for a 1/4” tool using a 21.51 CCMT carbide insert, and remade the parts I did last week. The parts are better and I feel better for that.

Will use this more than once a year, NO, was it a worthwhile , YES. If nothing else it was a pleasant afternoon in the shop.

Jack, how did you get it for $30. ?

Now that I'm getting older and have a small tool and limited funds, it's of interest.

The QCTP was a return, the list was $100, less the 20%, then at $80, then they knocked $50 as it was a return and a couple of pieces were missing (a couple of screws and the Allen wrenches, nothing too important).

That's getting close to suckage, right there.

Norm was here during most of the install process, he was watching parts of The Perils of Nyoka, when the best actor in the serial was the German shepherd, portraying Nyoka’s dog Fang. The rest of the cast were either cardboard or very wooden, but Charles Middleton (Ming in the Flash Gordon serials) had a staring role, good role for him, but the dog was better.

The QCTP was basically an afternoon lark, I was waiting for a series of emails (still waiting), so I had to be home. The cost was the real driving factor, the tool post’s ability to handle the small shanked tools, was also a benefit. This will be a tool that may be used once or twice a year.

Depends on the availability of your access to a milling machine, lathe and other machine tools. I don’t see them sold separately, at least not so far.

I believe I’ve seen some of the small stuff on amazon. I guess the next question though would be how or if they are interchangeable.

I had to do much the same thing. Get creative with the center bolt and compound and you're all set. I'm a low level machinist so it doesn't take much to make my happy.
