    Default What chuck is this?

    After decades of woodwork infidelity, I am returning to my first love and dusting off my old Tough lathe, originally purchased (bed, head and tailstock only) from Western Australia maybe 35 years ago.
    While cleaning off the accumulated grime of the ages, I found my old chucks - a Peter Child Coil chuck, a Nova chuck with Cole jaw accessories, a large expanding dovetail chuck, based on a single machined circle of spring steel for outboard use on large bowls or platters and another one, pictured below, which is my problem.
    This chuck has four alloy dovetail jaws that separate over a cone as the chuck ring is tightened. It is multi-function as it also works as a compression chuck using a two part split ring as well as a screw chuck when the two halves of the split ring hold the cone in place with a screw in it.
    I seem to recall that the expanding dovetails were retained in approximate place by a rubber band.
    Does this description remind anyone of any particular chuck? If so, can they remind me of the correct way to set it up?

    I agree with the rest, it's a PC2000 (or variant). I also agree there is lot's missing. But then again it is capable of being adapted into many variations.

    PCC2000 Chuck Parts

    I've got one in the garage but can't remember the last time I used it. I do have a manual I can copy if no-one else can direct you to an online copy.

    Hi, You have a piece of history in your possession. I can tell you a little about the chuck as I was associated with a business that imported a number of these units from Craft Supplies (UK) in the 1970-1980 era. There should be about 50 or more of them lying around in sheds.
    Peter Child was an English pioneer woodturner/teacher/designer/author in the 1970's. The chuck was the forerunner of most of the modern woodlathe chucks on the market today. It was quickly superseded by a Precision Combination Chuck manufactured by Robert Sorby & Co. and subsequently a lot more improved designs. Peter Child may have been the designer/inventor hence the name. A spring coil was introduced in design revisions to hold the jaws in place. What you have in the photo is complete except for a "C" spanner and a centre screw.
    The basic chuck worked well and there should be no reason why it could not be used again as long as you have patience in assembling it.
    Simply fit the base on the headstock,fit the centre cone,hold the four jaws in the outer locking ring with the aid of a rubber band and assemble it on to the threaded base. As you tighten the locking ring ,the jaws expand and lock into a dovetail recess prepared on the back of turned work. Very effective!
    A second function of the chuck used the two locking collets instead of the jaws and centre cone.
    A third function was to use the centre cone with a long woodscrew fitted from the rear held in place by the two collets and locking ring.
    I may have a spare "C" spanner out in the shed, but it would not be difficult to use a short piece of round mild steel inserted into the holes in the outside of the locking ring.
    Hope this helps.

    ps A fourth function was to use the base plate alone with three woodscrews inserted from the rear.

    I believe I also have one, fairly complete, still in the wooden box it came in.

    'Twas given to me by Rodent (also on these forums) and, from memory, includes a parts listing for two or three different models/sets/whatever.

    Sadly, I'll have to get home to check... got a few spare months to wait?
    I may be weird, but I'm saving up to become eccentric.

    I have a Masterchuck that was designed by Peter Child that I bought in about '92.

    The one that is currently called the Masterchuck looks a bit like that one.
