Made this jig and new tool rest this weekend after seeing many designs at the AAW Conference in Raleigh last weekend. Made with 3/4” square aluminum bars and a 2” round piece to cut the groove in the tailstock yoke. The 2” pivot point has a draw bar to keep the yoke from turning in the quill.
The carbide cutter on the end was purchased from Cap’n Eddie on YouTube. That’s attached to a piece of 1/2” round stainless steel bar. The laser pointing device is from Ron Brown’s Best Collection.
The yoke with the morse taper took 4 hours so its not a good repeatable solution with my small metal lathe. I have a few ideas how to make the next one that attaches the morse taper to the quill much faster but I would love to here some of your ideas how to do this also.
Fun little project, now I have to make some more hollow forms and vases.
Thanks for looking and feel free to supply construction ideas to make the next one better or more manufacturable.

Wow! That is awesome! Having metal working capabilities sure comes in handy!!
I recently converted a “Pet Laser” to use a 5v USB power supply for checking wall thicknesses. That really save buying batteries.

Very cool Bob! I like these rigs a lot and this is one of the better designs I’ve seen :-)
For attaching the Yoke to the quill, if I understand what you’re asking, can’t you just buy a MT to threaded arbor adapter and drill/tap the mating threads in the yoke?

HokieKen, Great idea, much easier to buy one at this low cost. Thanks.

I didn’t watch your video yesterday Bob. But after seeing it, I realize you used a drawbar to prevent release. The adapter I linked does not have a thread in the back for a drawbar. Just wanted to point that out when I noticed.
That being said, my gut feeling is that the drawbar is probably not necessary. There are obviously lateral forces at play but I would be surprised if they’re sufficient to release the taper fit. Then again, I have been wrong once or twice before….

Very Cool! I’ve been thinking about something like that myself. Instead of using the tail stock and MT, did you consider just making a stand that mounts on the ways? (Maybe that is what the 4×4 in your pictures is?) I don’t have the tools to make that pivot. I was thinking that maybe I could find an old u-joint and adapt half of it to act as a pivot?
Kenny, You really need one of these for that new lathe you’ve been refurbing.

One of these has been on the list since my first beer mug Nathan ;-) Of course that was 2 years ago and I haven’t even started thinking about making one. I do like the simplicity and robustness of this design enough though that it may not be a lot longer before I get started on putting one together.

Just a thought. A pen turning mandrel has a Morse taper on it. Could you cut that off and connect it to your yoke?

Thanks for the ideas guys. I think I’ll just drill and tap a hole in the back of the yoke, then Loc-tite a 1/2 bolt x 3” into it, then cut the head off.
Then use a #2 morse taper collet with threads in it to use the draw bar concept.
Insert the bolt into the collet and I’ll be done.
Lazyman, I did think about building a separate stand but want to cut down on the number of parts and the time to fabricate them.
