Hi Ishima,
More often than not on ebay, the people who seem to make a living out of selling old watchmaking tools break everything up into smaller lots, I image they make more money that way, usually the collets are sold separately, the motor & control is split off, sometimes even the headstock, bed, tailstock & stand are split apart. To people like me (and I image most of the people here) its a crying shame. To build up a full set means buying separate lots over time, you always end up with a frankenlathe and the original precision of a set of mating parts is lost.
You do get the odd lot go up with everything in it, and these seem to be very expensive - usually though, they are not! work out how much it would cost to buy all the bits individually and you'll get a higher number.
In your shoes, I'd consider a few different routes:
Contact some of the ebay sellers and ask for a price for a whole lathe set BEFORE they break it up (don't end up with them making a frankenlathe out of their parts bin) likewise the secondhand tool sellers onlne Contact your local horology group, they may know of a whole workshop for sale Cosie up to your local professionals, Watchmaker/Jewellers, clockmakers, they may have or know of, equipment for sale Buy new
I realise none of these options are that cheap, but demand for these items seems high on the vintage tools market, so prices reflect that.
Do you have any specific work planned that you need a lathe for, or are you building up tooling in general ready to tackle anything(mia culpa!)?
