  • OT. Any info on what this is?

    My Father wasn't a mechanic but he was a car (hotrods) guy and had enough tools to service and maintain them. He's not here now and helping my Mom reorganize her garage I came upon this. It looks to me like it's something to wind motors with. The part that is puzzeling is there is no way to introduce anything clamped into the chuck as there is no crossslide but sort of vice that mounts to two rails. The vice I'm guessing stays in place when being used. On the other side of the motor is two post marked - and + like you would hook up a meter to take a reading. So any thoughts?[IMG][/IMG][IMG][/IMG][IMG][/IMG][IMG]

    I wonder if it was a bench dynamometer for testing starter motors.

      Could be but it has a degree wheel on the end with a pointer that rotates with the drive. It has foward and reverse as well as a throttle type lever too. I tried to look up the maker online but had no luck.

        I think it's a generator tester

          Or for a magneto or distributer or generator?

            What's it say on the left front of the base (far left in first photo) and on the black part attached to the uprights (top of first photo)? Can you post a closeup of those two areas?

            SUN had red and black test equipment for starters and generators in the late '40s, so I think that's a good possibility. Something for generators would likely be belt-driven, though.

            Seems like most of the starters had end bells over the Bendix drives, so only the Ford 'longshaft' style would fit in that tester, if that's what it is. All of those are the same diameter, so you wouldn't need to adjust the height of the chuck.

            Is that a drag motorcycle in the background of the first photo?

              The chuck floats up, down and side to side. I can and will take some more pictures in the morning and post them sometime after. On the tag on the uprights in the center it says manufactured by WEIDENHOFF. Another tag says JOS. WEIDENHOFF. There's no date on it anywhere.
              Yes Sir, that's a dragbike.

                That machine looks like a distributor tester to me. I can't figure any other function for the degree wheel and the tachometer.

                  Jospeh Weidenhoff were (are?) manufacturers of magneto servicing equipment in the 1940s, it would seem that it's a magneto test bed of some type, this page has some of their wares - it may help you in your quest.

                  Also have a look at the Model 36 tester at the bottom of this page, it looks very much like your item.

                    Second the distributor machine. The lever on the motor adjusts the brush holder position giving variable speed. Variable speed is used to set the mechanical advance. They three jaw chuck grabs on to the shaft for the oil pump.

                      Third a Magneto/Distributer tester, Modernish Mags also had Advance units.
                      Probably a spark gap somewhere on rig. Mag coils go South if Spark can't jump out of HT leads...

                      Adjustable mounting to hold many sizes types of Mags. Most of which have Square or Rectangular Bases, See Clamp....

                        Gavin has it! I think it's the same as the machine shown in that ad.

                          I think that it's a device for winding coils. The "tachometer" is not for counting revs per se, but for counting the number of turns on a winding of some sort. I have a coil winder that is eerily similar...but not exactly the same. would work for any type coil on a genny, starter motor, mag, whatever.
                          There is no shortage of experts, the trick is knowing which one to listen to!

                            It says on the face of the tachometer "Revolutions per Minute". It's not a revolution counter, it is a revolution velocity indicator aka a tachometer.

                              It is if you've got a watch.
