    Witmer Coach in Lancaster PA Wheel Building

    in Technical

    Posted · Edited by mikewest (see edit history)

    I was in Lancaster PA today to pickup some castings at Cattail Foundry and a set of wheels at Witmer Coach that the made new. I took with me a set of wood wheels that had I wanted different hubs installed. Here is the big wheel lathe he uses  to grab  the outside  and  remachine the center to a larger ID. The machine uses the compound like any other engine lathe with a tool post  motor. He has a long end mill in the  compound and opens up the center slick as a mink. The machine is well over 100 years old. Ive never seen one. tHE JAWS on the face  plate are reversible  like any other  face plate.

    The coil was added by my grandfather eons ago. I recently got the car started after some preservation and it seems to run pretty good. The coil has a bracket with a capacitor but it has no wire.

     

    A friend helping with car thinks the spark is anemic, could be because of the lack of a capacitor?  How would I determine the correct one, if it is needed, and to hook it up?

     

    Thank you,

    Thats a GREAT LOOKING MOTOR! Keep a eye out for some period hose clamps will make it even better!!

    1910 EMF Ring and Pinion Backlash

    IMO 0.007 to 0.010 is a good ballpark to start with, then look at the pattern to confirm.  Just as important is keeping the backlash in the 0.007 to 0.010 range as you rotate the ring gear a full 360 degrees.  If there is too much variation, check the back of the ring gear and the mating flange on the differential for burrs or other high spots that keep the ring gear from fully seating.  You may have things apart multiple times to get it right.  Don't loctite or safety wire the ring gear bolts until you have the pattern and backlash set to your satisfaction.

    Good information!

    I am in the process of setting up the thrust washers and ring and pinion gears on the 1910 EMF. While there is some adjustment on the pinion gear (bearing assembly is on a threaded nut), I would like to get the spacing close with the right thickness axle thrust washers. My initial thought is to shoot for around .015" backlash. Does anyone have a feel for what the range should be on a new set of gears? BTW these are straight cut bevel gears.

     

      Thanks

    Andy, You need to get some white lead compond(use can use other things as well)  and pattern the  gears. Its quite easy.  Look on line and see what a correct o pattern looks like when the pinion is adjusted  correct , use a bar or some wood to load pressure on the crown gear and then rotate the pinion. The pattern wants to be not too deep in the crown gear or not to far out on the toe of the gear. Ive used plumbers pipe dope for black iron pipe seal before It works ok just to give you a image of how the gears are meshing. Make sure you clean the dope out of the gears  . Good luck
