I know this is slightly off-topic, and I'm ready for the accusations of
heresy, but is there anyone here interested in vintage electrical
machines? I have quite an enthusiasm for them.
I'll include some pictures of one of my latest projects, and my current
favourite electrical machine. This is a 2.5 hp electric motor built in
1931 by Laurence, Scott & Electromotors Ltd. I rescued it from a
demolition site last year. Overall it's in good condition. Just needs
new brass pipes for the grease cups, a good clean and a few coats of paint.
The motor and data plate:
I estimate that it took about 3 tons of force to remove the pulley so
that I could dismantle the motor:
The inside of the motor and the hand-made rotor:
After stripping the paint and coating with "Vactan" rust treatment:
After the last photograph was taken I stopped work for a month or two,
and I noticed a few tiny spots of rust appearing through the Vactan rust
treatment. I've found this treatment to be good in the past, but I
wasn't very pleased about this. I can't decide whether to strip it again
and re-coat with Vactan, strip and coat with red oxide, or just paint
over it and not worry. Any thoughts?
By the way, the motor is destined for a rotary phase convertor for
workshop tools. Should be done by the winter I hope.
