  • Power House Generator Question

    The judging standards talks about three different styles of Power House generators. The two earlier versions had 5 brushes and the one later version had only 3 brushes. I've been asked to look into having the black bakelite brush holder plates made. I've talked to one of my sources and he said that it would be no problem making it. Before we spend a bunch of time on this project we have a question about the earlier 5 brush holder plate. Was the only difference in the 2 earlier versions the location of the cutout? Basically I'm trying to figure out if there were only 2 different brush holder plates (1 for the 5 brush generator and 1 for the 3 brush generator) or 3 different brush holder plates ( 2 for the 5 brush generator and 1 for the 3 brush generator). I'll be contacting the archives for the prints but I just want to make sure I get all that i need.

    Also, does anybody see a problem with this plate being a different color than black? We will be making it out of a high temperature plastic, and the only sources we have found are not black. I figure this is an internal part so color really should not matter as long as the brush holders, and mounting arm parts fit and all of the slots and holes are in the correct spots.

    Any thoughts or comments before we begin on this?

    Thanks

    Jeff

    The differences are all external, the brush holders are interchangeable and will never be judged for number of brushes or color.

      Jim is an extraordinarily reliable source of info.
      And thanks Jeff for supporting the hobby the way you do!

        Will the new brush holder include all the metal parts in place, or do you plan on only making the Bakelite part and have the customer remove and install the metal parts?
        If all the metal parts are included, then I can see several sales coming.

          These are going to be just the bakelite part, but it will be drilled for mounting all of the brackets and hardware to it. I just don't see enough of a market in this to invest in the stamping tooling for those parts. As it is right now this plate looks like it is going to be approx $40 - $45

            That poses another problem. Attaching the metal parts without cracking the bakelight. I already have one with a rivit missing and no way to attach without braking it. Rod

              This also brings up another question. Will the proper rivets and rivet tool be included in the price?

                Rod, I have never worked on a powerhouse. Could a 10-32 or 8-32 panhead screw and nylock be used instead (do not know if there is enough clearance).
                Your issue is a huge reality of a problem.

                I just bought some window crank knobs for the Stude project we are working on and they needed to be peened over to attach them. I queried guy making them and he said the plastic would take the slight pounding required, he said the metal stem was not that hard. I put a micro-fiber over the backing plate and gingerly did the peening, expecting everything to go all to hell, but he was right, it worked fine.

                Maybe Jeff could comment on this, since his part will be plastic and not bakelite, which cracks just by looking at it

                  I'm asked quite often about brush adjustment and how they work, so hopefully these pictures will help.

                  by CarlR82A
                  Have any of you found a 3 brush powerhouse generator with a side adjustment bracket like mine? Field coils all original for 3 brush, screws never touched. Adjusting bracket screw also have never been removed or added. The generator is now on this late March or April 1929 car. ...

                  Third brush adjustment question
                  by Supergnat
                  While visiting a friend today he said his generator wasn’t charging and asked about adjusting the third brush on his generator. He had the band off and the brush could be easily moved to change the adjustment. I told him I would stop back tomorrow so we could make the adjustment. I read the tips write-up but have one additional question. After the brush is adjusted is there a way to secure it or...

                  Identifying Your Generator
                  by Tom Wesenberg
                  Over the years generators have been swapped on the Model A's, so now days you can normally have 1 of 4 different styles. First came the 5 brush powerhouse, then the 3 brush powerhouse, then the long generator known as the Autolite style. After Model A production ended and the Model B began, the generator also changed slightly, and now many B style generators can also be found on the Model A. People...

                  Generator adjustment
                  by camper#1
                  Generator puts out 18 amps driving speed. Third brush adjustment makes no difference. Discovered third brush wire shredded and disconnected. Soldered on new wire, new bearing, new brushes, same results. Third brush all the way up and still a study 18 amps driving speed. What could the problem?

                  Easy to do Preliminary Generator Tests
                  by Tom Wesenberg
                  I have a powerhouse generator to test for a club member. I came home to record snowfall, and it will take some time to shovel my way into my building with my generator tester. I figured I'll do a few preliminary checks to see if the generator needs to be repaired. First I connected my 6 amp 6 volt battery charger to the output stud and mounting bracket. The generator motored in the correct direction...

                  generator armature taper differences
                  by thom
                  I took the generator off of our '28 Coupe to the local shop to be repaired, and the guy is experienced in Model T & Model A generator and starter rebuilds but he ask me a question that I could not answer so I will ask it here.
                  Will Model A generators with the two different tapers interchange if you use the complete generator, pulley included? The armatures will not interchange from one...

                  Generator Question?
                  by Afordman31
                  My brother came over today and asked me to show him how to move the third brush to set the charging rate. I tried to move the brush and it wouldn't move. I looked at one of my spare generators and it moved like I thought it should. I then found a screw on the end plate that had to be loosened then the brush would move. Is this a early generator or maybe not Model A?

                  Name That Generator
                  by gdaquilina
                  This is the generator that was on the car when I received it in 1993. It has performed well, and I am trying to determine its origin. It has the oilers at both ends and two wires coming from the grommeted hole where the stud to the cutout is usually found. One of the wires is connected to the cutout, the other is a ground to the one of the cutout screws. The pulley is two piece, riveted together,...
