    FP1/Alexander Next Question

    Both screws were only lightly tightened so I think I will leave them like that. Presumably similar screws are not present on the FP1 Bob

    FP1/Alexander Next Question

    There is one screw on each side but they are different diameters Bob

    FP1/Alexander Next Question

    I wonder if you can help with my next question. I have started to strip down the my Alexander Toolmaster/FP1 clone, it is in pretty good condition. I am currently puzzled about the purpose of the grub screws on either side of the vertical slides. I have left the allen keys in to help you see...

    FP1/Alexander Spindle Lubrication

    That sounds like a good explanation. Presumably the catch troughs are still replenished by oil splash though.

    FP1/Alexander Spindle Lubrication

    Hi Ross Interestingly to fill the pockets the operating instructions tell you to advance the head forward to the 1” position and to run the machine at 750rpm for a few minutes. I wonder if there are some shields to stop too much splashing and that at the 1” they are not so effective. My machine...

    FP1/Alexander Spindle Lubrication

    Hi All, I have an Alexander milling machine which I believe to be very similar to the FP1. I was wondering if anyone can explain to me how the lubrication system for the horizontal cutter spindle works. Here is a copy of the relevant page in the user manual. If I am reading it correctly, you...

    SB 9c Gibb Screws

    I need to replace the cross-slide screws on my SB9c. If my measurements are correct they seem to be #12-28 UNF. These do not seem to be available in the UK, presumably because they are so similar to 1/4-28 UNF. Has anyone else had this problem and is the solution to open the threads up to 1/4...

    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...
