Sorry John didnt mean to rush you, especially as it might be a while before I get another bed. Although i must admit that the idea of a short but working lathe is growing on me. I might have to see if can use a freinds lathe to turn down the leadscrew, I normally wouldnt be to bothered but since this for maching ballscrews i need the thead cutting capability.

even if i dont start for a while I'm sure there are others who will benifit from your wisdom.....
thanks again
