Let’s use this thread to list the needs and links to sources.?

Hopefully we can find good drawings (if they aren’t in the files/photos already) and post them here too.?

I will start a 3D printing thread to help keep ideas and tips and files where we can find them.?

I’m looking for the dimensions of this tailstock part. So far, no luck. The threads are 5mm and 8mm x 1 left. I need the diameter of the area where the bushing goes and lengths of each of the areas. Also, there is a ‘bushing’ in there.?
If someone finds the drawings or can measure an existing set of parts it would be appreciated. I can’t find my original tailstock!?

Good afternoon,

I have my SL in pieces on the bench in front of me and have obtained the following measurements using digital calipers.

The part in question is 51.5mm long, being split 23.3mm for the M8 section and 28.2mm for the M5 section.

The M8 end is fully threaded. The M5 end has 13mm unthreaded adjacent to it's junction with the M8 section.

This unthreaded section is split up into 3 distinct parts. A 3mm long 4.5mm diameter section, a 7mm long 5.0mm diameter section and lastly another 3mm long 4.5mm diameter section. The central 5.0mm section is the part that fits into the bush.?
This layout can be clearly seen on the above photograph if I'm not explaining it well enough.

The bush is 11.6mm long and 12mm in diameter with a 5.0mm central hole.

I know a lot of the current threads are about CAD/CAM and 3d printing so I apologize for being a relic and just describing it.

Hope this helps.

That is perfect David, thanks for taking the time to do this. Good job!?

And, I got permission to post this drawing. It is from Bill at:



I was watching his video about the Unimat Tailstock and he produced these!?





Note the strange names on some of the parts in the original drawing.?

Thanks Bill!?

I will post these in the files section too.?

Strange names??

Yes, teasing in a way, but ‘guide pin’ for something that looks like a spacer bushing??
