    I have an old atlas lathe and would like to fit it up with a 4 jaw chuck. The Atlas
    lathe has a 1"10tpi spindle (yes an odd size). I found an spindle adapter to convert it to a more usable size but I see the chucks have another adapter to go to the chuck threads. Is this asking for wobble or worse?
    If this is OK what chuck do you recommend? thanks jim

    Jim,
    If your lathe has a 1" x 10 tip headstock spindle, and you are interested is using one of the chucks on the market, make sure that you purchase one of the lighter chucks. For instance, the Oneway Stronghold chuck, at lbs. would be too heavy for that size spindle. Whatever chuck you purchase, the manufacturer can supply the adaptor to fit your chuck. These are made to center the chuck body and allow it to spin on the lathe spindle with virtually no wobble. Usually, the adaptor supplied by the manufacturer will work optimally for the chuck you purchase.

    In your post, you mention a 'spindle adaptor'. I get the impression that what you mean may be a 'spindle extender'. If that is what you mean, then be forewarned that these kinds of adaptors can have a problem with run-out (wobble) because what they do is to place the chuck body or faceplate at a distance of 2" or 3" from the headstock. If the spindle extender is really well made, you might not even notice the runout, but it will be there.

    You can get more information chucks and spindle extenders on a variety of chucks at these sites:

    I hope this was helpful to you,

    Hi Matt,
    Thanks for the reply. The problem I'm finding is the chuck manufacturer don't offer an adapter that will mate to my 1"10tpi spindle. I just emailed to the links you send to see if they offer any they didn't state in there literature.

    the spindle adapter was just to convert to a more common size. thanks jim

    Teknatool (Nova) makes a 1x10 insert for their chucks (Insert C). I would stick with the G3 or standard SuperNova-2 chucks, vrs the Titan or Midi

    OneWay makes a 1x10 insert for their Oneway/Talon chucks (insert 0229)

    Vicmarc makes a 1x10 insert for VM90 and VM100 chucks (insert V00515)

    Personally I like the fact that the Teknatool has their jaws are designed to fit any of their chucks. I also like that Vicmarc has probably the largest variety of jaws.

    Hi Jim,

    Try this link to the page on the Oneway site where they list the stock threading for their adaptors:

    http://www.oneway.ca/index.php?option=com_virtuemart&page=shop.browse&category_id=97&Itemid=2

    If your chuck does not receive the adaptor for the Talon or Oneway chuck, you can go to this page to contact them and have them make a custom threaded adaptor:

    Merry Christmas,
    Matt

    Personally, I would pick a chuck that has the correct threads for my headstock. I would only use an adapter if I have an existing set of items (faceplates, chucks, etc) that are all the same size.

    The reason is that anytime you had an extension to the headstock you induce more vibration and the possibility of "off center"
