Does anyone make a lathe center drive that will screw onto a 1/2” bench grinder arbor?

That question has my curiosity in motion. What size CONTRAPTION are looking for, and what do you need something like that for? There are things that can be used, but I personally need more info than your question poses. ............. Jerry (in Tucson)

Is this what you are looking for? Not many sharpen their tools on the lathe anymore but certainly doable.

Check out the mini-lathe article in Shopnotes #73. There’s a page about DIY drive centers that may give you some ideas. https://archive.org/stream/ShopNotesMag/ShopNotes%20%2373%20%28Vol.%2013%29%20-%20Mini%20Lathe#page/n21

Thanks Ken. That’s where I was going with this. I had a similar idea but this really articulates the “how to”. I already have the coupling nut, I just need to pick up the threaded bar and get cutting and grinding.

Not sure what you want to do but after reading Ken’s link going need lot more hardware.
What is the max RPM’s of the grinder going to use? Are you talking a about 1/2” x 12 or 13 TPI or larger grinder spindle?

While might find a malleable steel coupling to fit the thread of your grinder spindle not sure that’s the way to go about it! That homemade drive center doesn’t have much tensile strenght.

Good luck with it!

Thanks Bill. I have a coupling nut. I’ll need the threaded rod to form the center point (although the tolerances are a bit worrying). I’m going to start by lathing wood and plastics. For a metal lathe I think I would be better off buying one made for it.
I don’t plan on it being an all the time thing so a homemade set up should work ok. Should I say. We’ll see and I’ll try to let the group know.
Thanks again. This is one of the best groups I’ve ever signed up with.

Have your say...
