    I can understand the problems with oil, the lathe behind the SB, a Prazi SD-400, gets a crunchy spindle when it's cold. But why should this lathe be any different from any other SB, who's spindle runs in the cast iron headstock bore (and I suspect that is the case, although it's purported there are exceptions, bronze bushings, even babbitt)?

    It isn't any different. Sometimes if a lathe with oil wicks sits for a long time it's hard to get oil flowing again
    The wicks in the apron are exposed to swarf ,chips and dust which oil works like a magnet to attract. If a lathe came from a really dirty environment new wicks could be a good idea. Considering its age. Just making sure clean oil gets to all the intended parts. Your lathe looks pretty clean.
    A lot of guys re-wick and clean oil passages to be confident it's all clean and getting oiled.. It's hard to tell if previous owners cleaned around the gits oil cup before lifting the lid to oil.

    Yes, and as I was going by the info.on lathes.co.uk, I thought there was the possibility of a different bearing type. Scared the daylights out of me! Nothing against babbitt or bronze, the nice thing about those types os they're replaceable.

    Thanks for all the enthusiastic replies thus far.

    Atlas/Craftsman gears aren't going to work anywhere in a South Bend.

    18DP....they "might" be the same as workshop series 9".....which are 18DP x 3/8" thick x 9/16" bore IIRC.

    9" gears will be too expensive. I'll investigate making my own, in plastic initially.
