    Great video. I really enjoyed and learned a lot. I am a subscriber now! Thanks!

    Good job, thanks for sharing the issue with the upside down video. I usually clean the front of an instrument with all keys and knobs removed, it is easier than polishing around all those pieces

      Cleaning while everything is apart makes good sense. Thanks for sharing.

    it seems your 355 is missing a circuit board that goes to that light blue slot behind the main heater fan

    Did you get this worked out? I also have a 355 and am curious how easy they are to work on.

      It turned out to be a broken switch (red and black on the main column). It required some disassembly, but repair was quite straigtforward.

    sorry, just to understand: it's the lathe lefty and the cross slide right? i have to buy a cross slide, but it seems that i find always opposite to what i need. i'm confused

    • @scottvance74
      @scottvance74 11 місяців тому

      The lathe is a left-handed lathe (as shown by the cross-slide) but is mounted backwards. So yes, it's confusing as posted.

    What kind of oil you use, and how much? Thanks.

    Hi, I have a Schaublin 65 and am looking for an index plate or headstock. Any ideas ? Many thanks.

    • @scottvance74
      @scottvance74 6 років тому

      The 65s are more rare. I see one about once a year appear on this site: www.machinio.com/?location=&search=schaublin+70#results. Another option is to place an ad here: www.lathes.co.uk/page3.html/ Best of luck!

      Glad that you found it useful! It turns out the headstock is probably early 60s I'm told.
