Model Forum / General / Models / February 2009tailstock chuck dilema
Hello group, Due to illness I have been forced to reduce the scale of my engineering activities, thus this is my first posting to this group. I hope it is relevant! I have purchased a very small second-hand lathe (it has no identifying manufacturers mark). It appears to have been manufactured to imperial standards. The tailstock id fitted with a dead centre which is in a parallel bore of 0.75 inch with a keyway and a thread which protrudes from the back of the tailstock for adjustment. I would like to replace the dead centre with a chuck (preferably at least 3/8 inch capacity, but all the tailstock chucks I can find have a morse taper fitting. Does anyone make an adaptor or is there some recognised way of overcoming this problem. In case it becomes relevant, the height of the dead centre point above the bed is 2.5 inches and the top of the bed on which the tailstock runs is a dovetail 2 inches wide.

Does the picture at the top of <http://www.cartertools.com/specific.html> show your lathe? In any case, they make Jacobs chucks with a variety of threaded holes to fit onto hand drills. One of those is what you need, 3/8-24 if the lathe is a Taig/Peatol. And plan to spend an evening browsing around the www.cartertools.com site, a treasure trove of information about the lathe. Tove Hi Tove, Thanks for those links. My lathe looks similar in principle, but older in style and less closed in. I will try and get a decent photograph tomorrow. I am at a loss to understand how I would attach a chuck of the type you describe, unless I got a 3/4 inch mandrel made to replace the one attached to the dead centre.

On ebay is an item described as DRILL CHUCK ARBOR 1/2" STRAIGHT SHANK x 3/8-24 THREAD but I would need one 3/4 inch dia.

JT6 on the end or similar to suit the chuck (better than the threaded types)and parallel turn the rest. Bob Not too sure about the accuracy of my turning skills! Plus, I don't have the motor set up yet, trying to sort everything else whilst it is accesible on the bench. Peter >> I think I have found something similar to what I need.

The dead centre itself turned out to be on a MT1 taper fitted in the parallel-sided "carrier" so the imminent purchase of a chuck on aMT1 taper should solve my problem. No doubt I shall be back with more problems before long!
