Yes that is correct. George Jacobs in 1907 did perfected the enamel insulation for the magnet wire. There is a slight conflicting historical notations between Mr. Jacobs and AC Gilbert company. I'm thinking perhaps AC Gilbert may be the first to actually patent it in an actual motor and history gave AC Gilbert more historical visibility in the model train world?
This is one of your best Doug. I have a question on the two monster motors, Where did the builder of the motors find or cut the worm shaft which has to be longer too reach the bull gear on the rear axle. If they just cut and drilled and threaded two worm shafts together how does the worm shaft not unscrew itself? I would like to build one for myslf.
You may not need a monster motor per se. Size is not the only determining factor for a more powerful motor.. If you use Gilberts standard motor wire, then a one inch motor is more powerful than the Gilbert Big motor (which comes in both 5/8 inch and 3/4 inches). Using an upgraded wire ( as mentioned in the video) in the 3/4 inch size can produce the equivalent of the one inch motor torque. As for the worm gear drive, one builder used the latest and last model 3/4 inch armature shaft (motor with the round commutator) which I believe have a slightly greater length. For the real monster motor necessitating a special elongated shaft, he "brazed" together enough length and then must be "trued" on a mini-lathe Producing one of these mothers requires a bit of good experienced skill. Not for the average DIY Hope this helps.
Great video, Doug!
Keep them coming! 🚂
Thank you. Glad you enjoyed it
George Jacobs is credited for enamelled wire.

Suggested wire to use would be the high heat double coated polyamide type.
