    This one is 1/2-10 single start.. both nuts are delrin, one nut is self adjusting/spring loaded, the other delrin nut is non adjustable..

    in the picture you'll notice an 18" steel rule for reference.. overall length is around 11"..

    I'll take $25 plus shipping, I'll do flat rate USPS

    next up is a 5/8-10 lead screw, it has a bronze nut on it, measures about 16 1/2" long overall... This was sourced out of a piece of salvaged pick and place machine.. the bronze nut shows some wear and is a little loose, it could be split to make it adjustable like an old bridgeport mill adjustable leadscrew nut...

    the threads are in good shape, the small threds on the ends are a little wore, but this is the end that can be turned down for the zero backlash coupler.... the ends would need to be turned down for bearings and zero backlash coupler, would make a nice strong leadscrew..

    $20 plus shipping, i'll do usps flat rate..

    Looks like a good deal for someone Bruce. I'm switching over to belt drive on my new CNC though.

    I'm going to use belt drive for Z as well. I'll continue to use the gear drive for the A axis though.
