"Thrust collar"

Hi, just joined. I have an old 9" bench lathe, model C I believe. I need a replacement threaded/clamp ring which may be referred to as a "thrust collar". It is fitted to the LH end of the main headstock shaft and beds against a fibre washer. Not having a lot of luck at finding a replacement from Grizzleys or anybody in Australia. I have sought a price to have one made - very costly, but it may finish up being the only alternative.

The original, as SB users maybe aware, is cast iron. I decided to remove it in an effort to clean the area around the "clamp", but, alas, it seems to have been resting there with a fracture for some time. It broke about 3/5 around the circumference while trying to unscrew it. The machinist who has offered to re-make one has suggested that it may no reliably braze on such a small cross-section.

Hopefully someone may have a notion or even possibly have such an item in a box full of unusual and rarely asked for parts or know where to point me.

Thanks to anyone in anticipation.

Ted (@sblatheman) might have one for you. If you can cob together the lathe so it will work for a couple hours, you can probably make one.

Put a washer against the end, and wrap the threads in copper or aluminum strip. Wrap that strip in a hose clamp (jubilee clip). Make the part on the lathe.

Thanks Allan. Now that is very clever; well for some one that didn't think outside the square that far, meaning me, of course. It does answer the question as to whether the late can run without any real great concern. Once made, is there a known clearance to set it at - like may be 0.005" for example?

Thanks n2zon,

There's a challenge I could accept. How do I make contact with Ted? Still a bit new at this game of forums.

Hi Chet,

I tried both eBay.com.au and eBay.com. Put the number given into the search on both but couldn’t win on either. Is there another trick to this, or do you think it may have already gone. Jolly good price.

I have them, N.O.S.
Shipping will probably cost as much as the parts.
