View Full Version : Lantern tool post out, QCTP in!

Well, I finally just did it. I took advantage of one of Enco's 20% off sales w/ the free UPS shipping and bought a wedge-style Phase II QCTP. I had been getting along OK with my old lantern-style tool post since making a threaded adjustment ring to support the tool in place of the wedge. You can see how I use it here http://bbs.homeshopmachinist.net/threads/59374-Tangential-toolholders-evovling-in-my-shop?p=852714#post852714. That is until I took a little too aggressive cut while parting off a larger diameter! Here's what happened:

You can see the ring warped, the threads failed, and suddenly it's only good for show-and-tell. . . . Luckily there was very little drama when it happened. The parting tool just dropped down. There was no binding or pieces flying or anything else getting broken, damaged, or injured. Lots of more experienced types said that this would happen, so thought some folks might be amused to see they were right!

Now I've got to tool up the QCTP past the 5 toolholders that came with the set. First up was a tangential tool to do turning and facing. Here's what I came up with:

I haven't had a chance to use the new tangential tool or the QCTP much yet, but it seems pretty functional. I did use it to make the knurled adjusting nut, and 3 more just like it. So far, so good! Next up will be another holder for a small boring bar, and a new clamp knurling tool, and a dovetail holder for my ball-turner, and. . . I'm off and running.

Looking good Jim! To me this is what HSM is all about. Being able to make whatever you want or need for yourself.:)

accept I thought the first project was grand, just needed a protective relief around the thread,
and maybe make from a prehard, for better resistance to deformation.

Thanks, Toolguy. You got that right--getting something new in the shop gives all kinds of opportunities for innovation. . . .

Material choice could have made a difference for sure. . . . I did make a replacement that I beefed up as much as I could. I was using a solid ring for parting after wrecking that first one, too! I guess I could've gone to a smaller size tool holder and then I'd have been able to make the ring thicker, but it was time to move on.

Oh, I'll keep the old stuff around--no doubt I'll get into a spot sometime when they'll work better than anything else.

That tangential tool holder is an inspiration. I may have to make one for my QCTP. Err, scratch "may" and insert "will".

Nice job.

That sounds great, Paul. I'd love to see it when you're done!

Jim, very nice work. Someday maybe I will be able to find the time to make some holders like that.

Well, it may be a while. My shop is still in storage.

But I will. And I will post pictures.
