Re: metric gear help

Hate to ask a stupid question , but are you using the
clutch or the half nuts ? What lathe , 9 , 10 or larger ? If you
go to the files section for the group & use the search in
the upper right for metric you will see several things for metric threading . HTH animal On 7/22/2022 4:02 PM, Daniel White via

Sounds like the worm drive key is riding out of position when the saddle is moved, I had a similar issue with mine after stripping it to install new felts, you can check this with a torchlight and see if it jumps out after moving it, if it jumps out it will allow about an inch of movement until it jams up.

Re: Two and Three Point Steadies
mike allen
Depending on the size of the car that the rotors came off they should make a good steady . I've been thinking about getting one from a small car to use for a base for a micrometer stand . Good luck with that project & keep us posted on the project . These are the kind of projects I really like then ones that are way , way out of the box ! animal On 7/20/2022 7:10 PM, TIMOTHY CRAVEN

Re: Two and Three Point Steadies
TIMOTHY CRAVEN
That sounds like a good idea. I was at a Ford dealership about a month ago and saw two late model rotors in the trash. They just looked so useable for something that I asked if I could have them.. I’m thinking that they would make great repurpose as a steady. Especially since I think the rotor has a stamped steel center and cast iron brake friction surface. Remove the stamped steel center and it’s almost good to go. Anyway, great idea.

Re: Two and Three Point Steadies
I am thinking of using maybe a 1 ton truck disk brake rotor to do something like this.
Has anyone seen this done before? The rotors are cast iron and very strong.

The south bend fourteen doesn’t use flat belts. It has a Reeves drive for variable speed and a main drive belt that I believe is like a timing belt on mine.

Don't know about your area , but I found a company
that makes belting one day when I was in Reno . They clipped up my
belt that I bought at Tandy leather & also made me a composite belt for $10.00 for my SB 9A lathe . Check in your phone book if you can find one or do a google for industrial belting in your area . animal On 7/19/2022 3:54 PM, Andrei wrote:

Re: South Bend Fourteen Lathe Drive Belts

Have you considered a linkbelt for a v-pulley? Better power transmission and lower noise.
Otherwise, for flat belts there are a bunch of ebay seller who make custom lengths, either skived or wire fastened.

It is dual V-belt.

We may get my friend's lathe fixed.

Tried retensioning the belts, but no real improvement. I suspect the problem is the Vari-Drive belt, rather than the spindle belts.

I believe the variable speed belt is the same as the older 14’s before the above date.
