Hello rdstars,
Darren has prompted me (not sure about being poked <G>) to comment on your S&B lathe. I have a Sabel which is essentially the same machine other than the QCGB and I have stripped and serviced it extensively. I haven't seen your other posts on this subject, so can you explain the problem in more detail? You say it has 'tight spots', that leaves plenty of scope for interpretation, but I don't think it should be a reason to sell the lathe. Is it tight once per revolution of the handle? That might mean a bent feedscrew or perhaps some minor damage to the feedscrew thrust bearings (plain face bearings).

The cross slide is pretty simple and I doubt that it can't be fixed. If it is tight at different positions it could be due to contamination and surface damage in the slide. It is obvious the cross slide in the photos is not original, it is too short and there is no top/compound slide, so there may be some other aspects that are non-standard, but I expect you can simply slide the cross slide off the back of the carriage. Slacken the gibb strip screws and just wind it all the way back till the feedscrew stops working and then slide it by hand off the back. This will give you the opportunity to check the feedscrew in isolation and have a look at the dovetails on the carriage and the matching area of the cross slide.

Has Darren mentioned the Yahoo S&B group? Have a look here:
http://groups.yahoo.com/group/smart_and_brown_lathes/

If you sign up there you can download a copy of the rather minimal manual for the machine and also the spares list which is useful as it has sectioned drawings of most of the machine.

Welcome to the collective :borg:

Nice job so far on the RD power valve. Got one of those in many many pieces. The engine is actually going into another frame eventually. Getting fitted into a Hawk GT (Honda Bros to you). What SSSA do you have on there? I can't make it out in the picture.

Hi Eric, Just wondering what is an SSSA?

Chears Richard,

Well the S&B crosslide or top piece is not original and the compound slide would be great, also the S&B takes up loads of room for how little it can swing. Been told it has a rare 3 jaw chuck on it. I dont have hardly any tooling for the lathe eather.

The slide is worn in the center, you can adjust the gib screws so its nice but then its a little to tight far in or out, adjust for the outers and its to loose in the middle. I skimed my ally faceplate that is home made and put a rule accross it and you can see light in the middle. Not sure if the saddle is say correctly as you can see when turning a little movement in the tool post.

I gess with a spair compleate sadle and everything attached it would be a great lathe. I have seen a friends Emco Compact 10 with full DRO and I do like that, or was thinking of following the Myford crowd as in the ML7. Seams like there is alot of parts avalible for them and also able to handle alot of work.
