I need to fix up an old lathe before I "loan" it to a friend who's lathe-
deprived.

I need a CHEAP 3PDT drum reversing switch with positive center OFF.

The old one has crapped the bed, and I'm certain it cannot be safely
repaired.

Need 3PDT, because this motor has four reversing leads. 15A, 110V is all
it needs, and it need not be pretty.

Some ChiCom units are on Ebay for under $30.00 including shipping, but
they're NEW, and they just won't "look right" on this old beater; if you
know what I mean.

I think that I sold all I had that I did not need.

If it is a single phase motor you can achieve this using 2 switches;
one double pole double toggle switch to select the direction, and a
single pole single toggle to switch ON and OFF.

Select direction of rotation prior to staring the motor.

Yes, Wolfgang, yes. I even understood how to do that when I hooked up
the original in 1971. I just wanted a replacement switch that sort of
matched the vintage and look of the lathe.

Wolfy, MOST folks who are on this group understand basic electrical
wiring, 'cept maybe that lamer who keeps asking things like, "can I hook
up lights in my new garage by using the metal studs as the neutral
wire... I only have one strand of #14. Oh, and can I run 4000W of lights
off that one wire?"

Whenever a Liberal utters the term "Common Sense approach"....grab your
wallet, your ass, and your guns because the sombitch is about to do
something damned nasty to all three of them.

Thanks, Gunner...

ACTUALLY, I sort of "forgot" that I own a couple of lathes G.

It took a bit of work to chuck up the oddly shaped drum itself, but after
figuring that out, I was able to re-machine the contacts with REALLY
light cuts so as not to break the phenolic substrate from cutting forces,
much as you would a commutator (but more delicate work). Although I only
left about 0.015" of metal, I think it's fine for 15A at 110V. The
switch was originally rated for 30A. The wipers took up the slack just
fine.

So, thanks all (even Wolfgang), but it's fixed and works.

Sure, put them all in series, and connect them to the 7200 volt line
at the street! ;-)"Lloyd E. Sponenburgh" wrote:

Most lathe motors do have 4 leads from the motor to the reversing
switch.

And most of the conventional reversing switches are 3PDT. Just a
unique configuration that most do not recognize as such.

Iggy,

I seem to remember that you were once tearing apart old BEST
brand UPS for parts.

Do you by any chance still have the keypad assembly which came
with some of the larger ones? Usually it pulls out of the front at the
end of a coiled cord with an RJ-12 (6-pin) modular connector at each
end.

Thanks,
DoN.

Ayup... but specificity is everything in requesting parts.

McMaster has four pole switches, and they are not outrageously
expensive.
