      The part on the right is not related, it looks like a keyless chuck with a #2 morse taper.

      Default Mystery Machine tool part... What is this?




      I found this item recently and have no clue what it is. The part on the right fits a tapered collet in the part on the left. There is a knurled knob on the back of the part on the left which tightens the collet. Looks like it was made to be used with the T slot facing up, since there is an oil fill on the top.
      There, I told you it didn't make sense.

        The BP collet is bored for the 11/16" tail of the horizontal arbor. The #2 morse taper will just happen slip into it almost all the way but that doesn't mean it is supposed to go there. I doubt someone made a #2 morse tapered bushing.

          I think the tapered thing is a Collis(?) tool holder. You put your drills or wehatever in a special tool holder and pulled back the knurled collar. Insert the tool and release the collar and the tool is locked in.

            Yes, the leftmost item is the lower part of a Bridgeport arbor support, these parts are used with the right angle attachment and long arbor.
            I have the top part.
            If you could send me your part, I only need to find the right angle attachment, an arbor and a Bridgeport mill.
            Regards

            PS, I don't know what the other bit is but I don't need it.

                more photos

                I have tried to attach some more photos. The one item does seem like a live center sort of thing. A plastic plug was installed in it, but I tapped it out. The taper end has threads inside, and it has bearings.

                  I got these from your profile pictures. Then copy the URL and use the image icon to show it, like this, but without the spaces:

                  I had to click on each picture to show it full size, then right-click, select "properties", and copy the full URL as shown above. It shouldn't be this difficult, and it is easier if you use your own image hosting or web space.

                    So it's a live center that has lost (or never had) the actual center part.
                    CNC machines only go through the motions.

                      Looks like what I did wrong was have an extra bracket in there. Thanks for posting them for me.

                        I decided to put both parts up for sale on Ebay. Got a bid on the support, none on the live center. 171175851113 171175808384 item numbers. So maybe the member who has the missing part can pick this up.
