The middle one is very dainty, do you want to see it......

Just ordered some delrin as a last attempt to salvage the leadscrews. Think I've got a worn 10mm lead, ballscrew kicking around that came with a motor I bought. Probably would be easier to rebuild that with new balls than mess around with delrin and leadscrews......
