    The Clausing service center has most parts for most of the Atlas equipment. Its usually cheaper than Sears as well. ________________________________ From:

      Hi Guys,
      I have been in the group for a couple of weeks or so after
      buying two old Craftsman lathes, Craftsman/Atlas 101.07383 and a
      Craftsman/Dunlap/ Double A 109.0703. The motor looks original and it
      has a date code of "M 41". It came with an 8" Atlas chuck model 10-
      885-t which is stamped "4 47" on the front. So my 101.07383 should
      be an early 1940's Craftsman/Atlas. It has what I believe to be non-
      ballbearing bearings as described in my 1937 copy of the Atlas
      manual. My lathe has numerous oil cups on it at all the bearing
      places. I just bought it before joining and it appeared to have the
      original belt which disenterated when I turned it on. I bought the
      motor belt from Sears but they didn't have the second belt so I took
      the old to a store and got one the same length. I have not worked on
      this due to back problems but when I do I expect to find the sintered
      bronze and babbit by the headstock as described in the Atlas manual.
      Hopefully this will help with the discussion on bearings in the
      early ones.

      Mike
