  • A small 4 jaw chuck

    I am in need of a small 4 jaw chuck. A 2 to 3 inch diameter would be close to perfect. I bought a 4 inch from CDCO and it was cheap, delivered on time and equal to the quality needed but it is huge. I looked at Shereline but they were out of stock for a chuck with independent jaws.

    The chuck will be in a non-powered situation for faily light loading. If you have one for sale that might meet my needs send me a PM. If you have other ideas share them in this thread.

    Thanks in advance

    I have a chinese 3" 4 jaw that I picked up somewhere a few years back for cheap. It's a little rough & sticky but usable after cleaning & lubing. It looks like this one:

      IF you do the EBay, there are a few meant for Unimat and one for a Compact 5 that looks to be quite a bit "thinner" than some I have seen...IIRC the Emco chucks can be a bit more compact

        Pete after posting I realized it might look like as if I were trying sell my little chuck but I'm not. I was just linking to that one to try to help you. Sorry if there was any misconception.

        If you need any measurements or weight of mine, let me know.

          I already bought it's sister. It is too heavy. Thanks for the input, I knew you were not selling. Hopefully somebody has/knows of one for sale. For this project it would help if it wasn't "Gold Plated".

          Thanks again

            Pete,
            Would a spider like used on gun barrels do for your needs? Just 3 or 4 bolts for jaws.

              The Taig 4 jaw is well made and reasonable price-wise. http://www.taigtools.com/c1030.html

              I have just completed some finicky jobs using it on a 4" rotary table.

                grab a unimat 4 jaw from ebay. They are well made and you'll be able to sell it for what paid for it if its a temporary need
                .

                    To try to answer all the input. 1) It is a keeper not a one timer. 2) For what I am doing a spider will not work. 3) It would be nice to have some dimensions as to thickness of the various offerings. If you have any of the options presented could you give me a quick set of measurements.

                    There are two things I don't want to do, One I don't wish to buy another of the wrong size and two I don't want to build one.

                    I appreciate all the help so far.

                        Thanks for the info. That looks like it could be the ticket. The 1.25 measurement is much smaller than the one I bought.

                          Those Taig chucks have always looked weird to me...... littl body, and huge outsized jaws coming off it.

                          Maybe the new ones are not like that?


                          Looked at the link.........I'm thinking of the three jaw....... The 4 jaw looks fine,

                            Pete,

                            Any good to you?

                            I had a look at one a year or so back, the jaws moved very nicely.
