I think you guys have convinced me to go the “Shopsmith” route to mount a chuck. I know there are thousands of Shopsmiths around, but it feels funny counting on that little set screw for the whole shooting match! I know I m paranoid.

Opinions on chuck brands? It won t see massive use, looking at Grizzly, Nova, Oneway. Any cheaper off-brands worth it? Oneway looks to be the standard, but pricey. But I guess buy once, cry once.

Anyway, thanks for the great discussion gents. As you all know there is precious little info available for these things. Which I didn t know when I got it from my dad. It s got more shop dings than wear, I suspect I ll be using it for a long time. So far I ve used the lathe and drill press, but I m planning a project for the band saw and jointer next week.

If anyone has any other tips on maintenance I m all ears.

If you go the Shopsmith route as you say, I can’t stress enough the “tapered flat” on the Shopsmith spindle. It’s a must. One also needs to ensure that the setscrew fits snugly into the arbor of the accessory being attached to the spindle. A sloppy fitting setscrew could lead to a disaster!

I don’t know if there’s a best chuck out there, but I have a couple of Nova chucks and have never had an issue with them. You need an adapter to mount one of these chucks on a Shopsmith spindle. Either the “F” or the “S” adpater. Both the Shopsmith spindle, but the “S” is the newer version and the preferred one.

GordonB I wouldn t recommend the Shopsmith in expanding to woodturning.

Sorry I wasn t clear. By using quotes: “Shopsmith” in describing my plan, I meant the Shopsmith mod, as in 5/8” shaft modified with a “tapered flat” in an R8 collet.

Ted, Thank you. I do hear you and understand, and GREAT pictures earlier in case I didn t.

I have seen a few Shopsmith accessories with 2 setscrews. But I cannot find a spindle adapter that way. Anyone seen one? Mostly thinking Shopsmith to 1” 8TPI as that seems to be the most common out there with the most options. Any downside to either adding another setscrew…or for that matter drilling the shaft to give even better bite? IDK, just wanting more security. Probably overkill.

I’ve had and used Shopsmith equipment for almost 40 years and have never seen a Shopsmith-made accessory that uses two setscrews to attach something to the 5/8” Shopsmith spindle. And, I should add that I have most everyting made by Shopsmith. There’s one setscrew that lines up with the Shopsmith “tapered flat’” on the spindle. One setscrew is sufficient.

Using the Shopsmith to 1” x 8 TPI adapter is fine if you get a chuck that has 1×8 threads without needing an adapter. There are a number of chucks like this that thread directly onto a 1×8 spindle. On the other hand, if the chuck you get requires an adapter to mount to a lathe (the typical Nova chuck) you’d need two adapters, one to get you from Shopsmith to 1×8 and a second to get from 1×8 to the threads on the chuck.
