Milwaukee bi-polar electrics EP-2 .
Re-motoring two of them.
They are by Custom Brass. I painted one about 4 years ago. The other was already painted by the previous owner.
With conversion to DCC, the open frame motors need replacing.
Some brass sheet stock used for making the motor mounts.
Each electric has two motors. Some large tin snipes to cut the brass.
The kid's old workbench vise used to bend the brass stock. A hobby hammer used to get a good 90 degree bend.
Dividers used to transfer motor holes to brass stock and dimples put in to guide the drill bits.
Pilot holes drilled in the brass mounts.
The motors took 2.0 mm screws.
The large center hole had to use about 5 different drill bits, increasing in size until desired hole was attained. Using just the needed large size bit would have damaged the thin brass metal plus accuracy is highly diminished.
Brass motor mount drilled/tapped into base of the electric's frame using 2/56 screws.
The motor just fits inside the super structure.
One set done.
