Hi,

Did some one say photo?

Well OK, go here to see the 1" x 8 threads per inch one.

Photo was removed

The one pictured is from Penn State, at least the one I got had some issues. It is from China and the class of threads used for the set screw to hold it on the shopsmith were such that it wanted to come loose all the time. I contacted Penn State and gave them the information to fix the issue but I have no idea if they ever did. I did have some luck by buying a longer better quality set screw and some locktite like product that still allows the screw to be turned but seems to keep it from coming loose on its own. I still don't trust it so someday I will drill a second hole 90 degs from the first and tap for a standard setscrew and use that to hold it on... or trash it and get a better quality one.

Lathe Chuck Adaptor

Yup, as usual reible has set the "photo quality" bar high. I have a few respectable photos but very few that come up to this level especially when doing closeups.

But that is OK, about a year ago (maybe a bit longer) I was just learning how to post photos. If it had not been for my interest in this forum, I would still not know how.

Thank you ed for this photo. It makes it very clear what this adapter is suppose to do.

Other than arbor size and thread, are there any other types of adapters?

Are these all readily available or does one have to go to a specialty source (like Penn State)?

Three questions
The first for anyone. Does anyone know of another manufacture of adapters other than Penn State? I don't like the sound of that adapter as explained by Reible.

Second question to Reible - Instead of drilling a new hole or using locktite could you simply use a set screw with a nylon insert that would keep the screw from backing out?

Third question does anyone have a picture of the adapter that comes from SS when you order the Talon chuck?

I don't have the Talon chuck, but I bought the G3 from SS and here is the chuck with the adapter. I couldn't get the adapter loose from the chuck, but they all look the same except for size.

Yes but I don't recall where I saw them. See post from #4 from Paulmcohen and since he owns one maybe he can tell us???

The problem is caused by having the wrong "fit" threads in the adapter, and second the setscrew they supplied was short and "soft". I picked up a replacement that was longer and thus had more threads in contact and added the "locktite" like material because I had it. It is a metric thread, don't recall the size now but if you happened to have one with the nylon insert it might work as well?? I know I would feel better with a new hole and correct threads and would go to a stardard size hex like the rest of my shopsmith equipment uses... Now the way it is you have to have a metric allen wrench to use.

I now have a Nova G3 with the correct adapter from shopsmith so the 1 x 8 tpi adapter doesn't get used much. I could part with it but I would never sell it to anyone knowing what I know. I do hope to get around to trying the new hole and threading if for no other reason then to see how it would work.

Sorry I don't have a talon chuck or adapter to post pictures of. I see a picture of the G3 has already been posted which is the same thing I have...

How does your adapter connect to the G3?
To see the talon adapter.

After reading your post last night, I searched the oneway web site. I found this - http://www.oneway.ca/chucks/adaptors.htm But not knowing much about lathe chucks I decided not to post it until I could find out a little more. Wow! your response has been wonderful. Thought I'd just throw this in the mix for a little confusion. Looks to me like they have adapters for just about any chuck. They cover imperial threads as well as metric. If you don't have your answer by now - you could give them a phone call.

Thanks for that site Chuck. It was interesting and I found out that the adapters screw onto the chuck. So ALL adapters look the same one one end, the other end varies from no threads to the threads of your chose.

So to answer RalphTaff question, YES a OneWay brand will fit the SS, all you have to do is purchase the correct adapter. If you change to a different lathe, like a OneWay or Jet. It just needs a different adapter with threads.
