    Overall length is about 1100mm and I think from memory its about 1" dia. I haven't been able to measure it closer than that atm as its all wrapped up in bubble wrap. Some time ago I offered it to a bloke who had bought a metric Nuttal off ebay but it all must have become too much for him to organise the freight and its been sitting here for a couple of years now all wrapped up.
    If yours is around that length I'm happy to unwrap this and take some more accurate measurements.


    For those with out a qcgb something like this might be worth considering. Theres a lot of this sort of thing out there apparently. It might be cheaper than making/sourcing gears etc

    Evening Bollie, not sure if Eweee's pm'd you re the Nuttal ls. I measured mine - it looks to be 1400mm x 22.2m. I'm interested in your electronic ls - has anyone on the forum trialled this? Mark

    Thats a fantastic offer Bollie
    As Mark said though its a bit short and i have cut all my gears to suit my metric screw. Its really not a big problem, unless i want to thread right down the RH end of the bed, i jest need to pin it together somehow so the endplay is sorted.

    As far as the ELS, i like the idea hence my looking into an EFS (electronic feed shaft) but i somehow feel better when cutting threads knowing that the screw and spindle are mechanically linked.....silly isn't it?

    Cheers,

    No problem mate. re pinning yours. I reckon the right grade of Loktite, applied correctly would probably solve your problem.
