    I have had mine for a few years and find it a very handy tool to have around...I originally had a 3 jaw on it but have now put a 100mm 4 jaw on it.. It just consists of two opposed tapered roller bearings on a Mt3 arbor with a backing plate a slip fit over the bearings...

    I saw this posting and thought of the Lodge and Shipley Oil Country lathe that one of my former employers had. It had a 12 1/2" bore through the spindle with a big 4 jaw chuck on each end. It was really good for large hydraulic cylinder rods and cylinders up to about 12 1/4" od.....On occasion we would have to put a table some distance from the rear chuck to support the rod we were turning.

    Been using mine for over 7 yrs for misc pipe from 1.5" to 12"

    It is real useful to have around.

    It's called a chuck center and Royal and a few other sell them at a huge price. They're easy enough to make from an old drill shank and some bearings and plate. That is, unless you want real spindle bearing performance; then you have to be fussy.

    I have a 4" three jaw and a 6" 4 jaw I use for chucking on the tailstock end. I bored a 60 degree conical taper in the back of their solid solid back plates to take the live center. Works good on the rare times I need one or the other.

    When I first saw your subject, I thought "Sure, I do it all of the time" But after reading your intro, I realized that I was thinking on the other plane.

    I have a small 4" chuck that I will often chuck up into my larger 11" dia chuck. I use this when I don't want to change over to the collet chuck but I need to grab something small in diameter, which the larger chuck will not close down to.

    But I had not thought of using a chuck like you had mentioned. All sorts of new projects now come to mind.

    Alistair & Mark

    I have seen a rolling tailstock chuck employed to part off a long piece of bar that was greater in diameter than the lathes spindle bore, a fixed steady was employed twixt the two.

    regards

    Thanks guys mark as you know, I already have a rotary table with a built in chuck .I was thinking of between centres but as has been pointed out here,it should not be fixed but must rotate.thanks guys so far.Alistair

    trouble is i cant think of any posibilities in a lathe tailstock.
    what would you do with it Alistair.
    a better use for it would be in a rotary table I think....or if you could some how get it into the main chuck of your lathe ..then you could tranfer the work over for further machining on the rotary
    all the best.....mark

    I believe what you are looking for is often called an armature chuck. You see them on eBay fairly regularly.

    Are you talking about a revolving chuck or a fixed one?

    I've had a revolving one for about 3 years, there was a spate of them appearing on ebay from E. Europe & I fell for one. Used it no more than three times but two of those times I'd have struggled without it. I know fixed ones exist but not sure what you would do with one?

    two chucks on a lathe at the same time ???

    I recently have been impressed with a small scrollchuck 3 jaw not a jacobs but full size chuck with a mt3 taper shank which would fit neatly in my tailstock allowing numerous possibilities has anyone tried or heard of this is it a gimmick or neat tooling accessory?Alistair
