I’ve just gotten a new Grizzly G0766 lathe which has a 1-1/4”x8tpi spindle size. I have three chucks for my metal lathe which are 1-3/4”x 8tpi (one which is a very expensive, custom made for turning and boring tobacco pipes) that I would like to be able to use on the new wood lathe. I have searched high and low for a spindle adapter to take me from 1-1/4 to 1-3/4 to no avail. I could make my own adapter but by the time I buy the 2” rod stock, drill bit, boring bar, and cutter, I’ll have a buncha bucks tied up, so I would really like to find a ready-made if such an animal exists.

Is anyone aware of anyplace such a thing might be found?

OldCorpse, looks to me like you’re going to have to make an adapter, unless you know a machinist that already has all those things you say you need. It should cost you somewhere near 50 bucks if you have that friend.

Now, if your favorite chuck is a 3 jaw, you might want to rethink using it if you’re going to be making bowls. Wood turning chucks can be had for as little as 100 bucks with the adapter being about 18 extra.

If possible, post a picture of your chuck. ............ Jerry (in Tucson)

Oneway or Nova or both will make custom adapters, unless I’m mistaken.

Metal lathe chucks don’t always work well for woodturning and accessory jaws set may or may not be available. Some metal chucks just not safe to hold wood but not looking at what you have.

I like and own two Oneway chucks you might like them too! Nova chucks are also popular. I like Vicmarc but don’t want to spend the money.

Super Nova 2 will need a threaded insert or Titan2 chuck direct thread.

Well, it appears that I’ve had one of those famed senior moments that seem to be becoming more regular as the years roll along. Actually, the one chuck/jaw-set that I was wanting to be able to use on my new lathe was one that I had shop built for turning tobacco pipes. The unique thing about these jaws is that they contain indexing pins which allow a briar block to be turned, the tobacco chamber bored and then, by slightly loosening the jaws the block can be pivoted on the pins, thereby positioning it so that the stem/smoke hole can be drilled, precisely aligning it with the direct center of the very bottom of the the chamber. Here is a photo of one very similar to the one I built:

All the time I spent searching for an adapter and asking you good folks for help was completely unnecessary since, as I was moving things around to get my shop into a configuration accommodating my new lathe, I looked at the jaws and had an Aw Shi….rley! moment: I’m just coming out of a forced 2-year hiatus due to an ankle surgery gone awry, and had forgotten that the jaw set was mounted on a six-inch face plate. DUH… I have a 1-1/4 inch x 6” face plate that came with the new lathe, so it’s merely a matter of drilling two holes and bolting the jaws onto it and I’m in business.

I apologize for bringing my non-problem to y’all before I had taken the time to investigate my situation thoroughly. I do appreciate the time you’ve taken to respond to my request and for the suggestions you’ve made.

BTW: I do already have a Nova G3 which I had purchased for my midi-lathe. I love it, and will be looking into buying either a Titan or a Super Nova… as soon as my wallet says it’s okay. :-)

No apology needed some folks use their small metal lathes to turn pens all about the chuck that comes with the lathe. Think your face plate threads are 1 1/4” by 8 TPI so should be no problem getting what you need it to do!

Think in many ways other than minor differences our four jaw chucks modified for metal chucks. Of course jaw sets a lot different.

Good luck with it!
