I have made steel mandrels with screws sticking out to be able to mount things to turn. I had this dream about making one totally out of wood that you can just tap into the More#2 taper on the spindle so I made a few- 2 walnut and one mahogany!

I roughed out a blank and then turned the Morse #2 taper on the Southbend lathe with the taper shoe set at a perfect #2 taper. Then I tapped it in the wood lathe and laid out a pattern of 3 holes at 120 degree apart using the index wheel. I then mounted a round piece on the end that I put a screw into for use with Yo Yo’s and such things. The problem with my design is that the screws did not line up the center perfect so the screw had some wiggle when the round plate was remounted on it.The next try was with 2 dowels to locate the plate so when I drilled the hole, took it off to put the screw in, and then remounted it, the screw ran perfectly true .

The next thing is to cut some yo yo blanks.

Prior to this I made a mandrel that was half wood for the kids at school. The screws were going the other way so the heads were seated in the outer piece with the drive screw and it lined up perfectly when I installed the screw The plate was mounted on a 1”-8 hex nut.
Two yo yo’s were turned today at school on this one.

Cheers, Jim

Looking good Jim.

-- Bob, Western Australia, The Sun came up this morning, what a great start to the day. Now it's up to me to make it even better. I've cut this piece of wood 4 times and it's still too damn short.

Jim, nothing better than having a dream and have it come true. This would sure be a good teaching exorcise for the kids at school showing them there is a way. I believe you and the lathe make a good team. We all can learn a lot.
Now I may have to try something similar to free up a chuck.

Interesting approach. I’ve done something similar for turning refrigerator magnets. A much smaller one, but a screw chuck nonetheless.

When and if I get lathe some day I would have to review all of your lathe jig projects, there are many useful staff you’ve made.

Thanks you for looking and the nice comments.

Hi Lew, I’ll take a series of shots when I have the camera back in the barn and show you how I do the indexed drilling. Usually I do the center drilling in there to get the locations and then do the drilling on my drill press where I can control the depth better.

Hi Barry, I also do the Refrigerator magnets like that with a much smaller screw. This is a #8 screw and the magnets take a #6.

Hi Bambi! you won’t have to wait long!!

Hi Ivan, hurry up and get that lathe. It will open up a whole new avenue of woodworking!!!!!!

Cheers, Jim

metal lathe is sure handy to have in the wood shop. Opens up a whole new world of making tools you don’t have.

Hi Lew. I took some photos of my drilling rig I use in conjunction with the index wheel for doing hole layout.

This is the assembly that sits on top of the banjo at exactly the center of the spindle. It is an aluminum block with a top cap that clamps down on a piece of tubing with oi lite bronze bushings and that was bored to fit the sliding drill shaft.

The drill shaft is a steel tube that just slides out of the bronze bushings and it has a bearing in each end to support the center drill shaft with the chuck on the end.

It was not too hard to assemble but that drill shaft with the 2 bearings would be mighty hard to disassemble.
I typically do all center drilling in the lathe and finish the drilling on the drill press where I can control the depth..
I hope this help …...........Cheers, Jim
