    Grafting New Cross Slide Screw

    I suspect that single pointing the new thread will not be possible for me as the only machine I have is the one I am refurbishing. Any machining I do will have to be with the cross slide locked up and the compound swung round. Has anyone had any experience with the screw and nut refurbishment...

    Grafting New Cross Slide Screw

    That is a very useful and detailed set of instructions, thank you very much for taking the time to write them. One further question, I am based in the UK and 7/16" acme rod is unobtainable but I can get 1/2". I think I could use this if I tap out the nut to the larger size. I think there is just...

    Grafting New Cross Slide Screw

    Now there is food for thought. The suggestion by Texasgeartrain is the opposite of what I was going to do. I was going to completely cut off the old screw, drill the remaining stub and then turn down the new screw so it can be pressed or screwed in. This would mean that the graft could be a...

    Grafting New Cross Slide Screw

    I have been looking at various discussions about grafting on a new cross slide screw. Everyone seems to bore out the remaining stub and turn down the end of the new threaded rod to fit with various levels of interference and sometimes Loctite. Has anyone ever tried threading the components and...

    SB 9 Dial locking screw

    Thanks for the replies, at some point when I have reassembled my lathe I should be able to confirm the sizes. Here in the UK Imperial Unified threads although not rare they are less common than Bristish Standard Whitworth (BSW), British Standard Fine (BSF) and British Association (BA). The BA...

    SB 9 Dial locking screw

    Does any one have the details of the cross slide and compound slide dial locking screws and also the screw that’s locks the compound nut in place. Mine are all missing

    South Bend 9 Cross Feed Thread Conversion

    Two reasons why it might be worth doing. One financial and the other practical. Here in the UK 7/16-10 acme threaded bar is unobtainable off the shelf but 1/2-10 is readily available. I know I could import some from the US but that is still more expensive than the 1/2-10 stuff here. Larger...

    South Bend 9 Cross Feed Thread Conversion

    Did you make a new nut from scratch or did you modify an existing 7/16" threaded one? I was wondering if I could drill an existing one out to 1/2" which would presumably still leave some thread there and then run a 1/2" tap down it. Not sure about the accuracy of doing that.

    South Bend 9 Cross Feed Thread Conversion

    The current 7/16” screw is 10 tpi so I would replace with 1/2” 10 tpi so the dial should be unaffected.

    South Bend 9 Cross Feed Thread Conversion

    Just wondering if anyone knows if it is possible to change the cross feed screw from 7/16” acme to 1/2” acme. At first sight there looks to be enough room to me.

    South Bend 9C Tail Stock Disassembly

    Thanks that sounds like a quick neat way to get the alignment pretty close. Thinking about it overnight I now think I am going to reassemble the tail stock without the shim that I have found. That will give me a much better idea of the basic condition of the machine without any possible...

    South Bend 9C Tail Stock Disassembly

    Thanks I have got it apart now and found a 0.015" shim, so I am obviously not the first person to open it up. Once cleaned up I think I am going to reassemble with the same shim but it looks like I am going to have some alignment fun once the lathe is back together - which will be a while yet!

    South Bend 9C Tail Stock Disassembly

    Hi The complete strip down of my SB 9C circa 1942 continues. I have now started on the Tail Stock. I have removed the Quill and the feed screw but I am puzzled about how to separate the Tail Stock body from its base or even whether I should not do this. Any advice would be welcome. Thanks Bob

    SB9C Take Up Washer

    I have just started to think about refurbishing the headstock on my SB9C. Just wondering what peoples views are on replacing the Take-Up Washer with a new flat bearing. The washer I have just removed looks reasonable but a bit scored and is about 0.060" thick?

    SB 9 Leadscrew Bracket

    Anyone know why it isn’t just plain brass bearing

    SB 9 Leadscrew Bracket

    I had never heard of it but Wikipedia tells me that it was used as a cast-in-place bulk bearing material. The Leadscrew scored the bearing a bit as it came out as it was quite well jammed in Any suggestions about any remedial work required. Thanks Bob

    SB 9 Leadscrew Bracket

    I have just removed the right hand leadscrew bracket on my 1942 SB9C. The bearing seems to be very soft, does anyone know what material it should be? Thanks Bob

    Model 9C Reversing Gear Body

    Thanks for that. Presumably the lubrication system was modified when the reversing gear system was changed. Perhaps there were problems with the original design.

    Model 9C Reversing Gear Body

    I have now dismantled the Reversing Gear on my circa 1942 SB 9C. It is one of the old style with the square retaining bolt. The gear body seems to have just one oil passage instead of the 3 shown in drawings for the later design. Is this correct or am I missing something? Also there seems to be...

    What is the purpose of this bolt

    That seems to have been a more interesting question than I had anticipated. I know that you cannot really tell but mine looks to be factory drilled. I now have a question about the Reversing Gear Body but I will start a new thread about it. Thanks Bob
