  • ID mystery objects please

    got some things to id
    the first is some sort of adjustable motor mount .. its about 10 inches x 8 inches



    view from underneath ..it's a very presice mechanism that moves it over 1/8 of and inch for 2 inches travel of lead screw ...feels very well made.



    Second item is some type of motor ..stepper maybe ..
    no markings or id on it ..theee pins on the plug..but only two wires come out of the plug ..no idea what voltage ..nothing its about 2 x4 x 3 inches






    sugestions for alternative possible uses welcome

    all the best..markj

    The small motor thing looks like the headstock for a small lathe. Meant to plug into a power supply. The three prong plug is for keeping polarity correct.

      What does the tag on the green thing say?

        I'd hazard a guess that the first item is used to give variable speed with a constant speed electric motor. Motor pulley is spring loaded on one side so as the tension knob is tightened or loosened the center to center of the drive and driven pulleys changes and the one half of the pulley can move in and out against spring tension giving a variable diameter pulley. The angle of the slides should match the angle of the pulley so the V belt is kept in alignment.

            Do you know what the worst thing is .

            i paid a £1 for that motor drive unit

            I now realise, that i picked up and examined the rest of the lathe...which was in its component form ..just looked like bits of plastic extrusions to me ..spread out in other areas of the car boot stall....no way did it look like a lathe to me

            2 weeks ago ./..will be very lucky if the guy turns up this Sunday ..and he still has the other bits and peices....crossing fingers.

              That green mounting base is a nicely made unit!!

              Thanks for posting these very interesting objects.

              we need a "What the Heck Is this" thread.

                Mark,

                I had one of those Unimat lathes in my hands a few years back, it was brand new. And about the nastiest thing I've ever come across. Plastic slides that jump & jerk, handles too tiny to wind - really, I couldn't think of a single use for it. I tried checking for burrs / plastic casting flashes, lubricated it, tried adjusting the slides, waste of time.

                Too insensitive for anything small and accurate, too sloppy for anything bigger. The bed, headstock & cross slides slip out of alignment, hopeless. Probably best used for gathering dust on a shelf somewhere.

                If you meet the guy again, give him the headstock back...

                    Would the headstock be any good as a toolpost-mounted milling attachment for a real lathe? on the lines of the 'Quickstep'? Or is it too flimsy even for that?

                        That 66 Watts might be the stumbling block, you wouldn't cut much metal with that. Maybe tiny endmills would be OK.

                          If it was kept within it's limits it would work just fine.

                              Are you sure it was a Unimat? I have a very old one, the DB200, and it is a very nice little machine when used within its limitations.

                              This is it with a 1/2 hp variable speed DC motor transplant.



                              It turns steel using a carbide bit quite nicely.
