After doing some running around today with SWMBO, and mowing the lawn, I
got a few minutes in the shop. I really hope I get an hour or two
tomorrow, because I need to make forward progress on my WW project(s).
I put a tool together. It's electric.
My great-grandfather bought some machine tools. I never met the man; he
passed away before I was born. Anyway, he had a lathe and a drill
press. The lathe made it from my grandfather's house to my father's
house in 1976, where I played with it a bit. It is currently at my
brother's in-laws. I was up for a visit last month, but didn't have
room for it in the car.
The drill press made it from my grandfather's house much later; it only
got to my dad's house after my grandfather passed away. My dad had no
use for it, so he said I could have it. He thought the motor was bad.
And the power cord definitely had seen better days. Anyway, on the
visit I mentioned before, I did have room for the drill press in the
car. So it came with us, all wrapped up in burlap, four separate pieces
(head, motor, table, and stand).
I tested continuity on the (paired) winding; showed an ohm or two. The
switch showed resistance off the scale of my multimeter when open, and
less than an ohm when closed. The leads on the multimeter show about a
half an ohm resistance when shorted together, so I think the switch
closes well enough. Didn't find any shorts from any of the switch or
motor contacts to the switch or motor frames. So far, so good.
I walked to my local hardware store, and spent $10 on a 25-foot, 14
gauge extension cord. Cut it in half, and wired the half with the
three-prong plug up to the switch. Plug it in, no surprises. Throw the
switch, and the motor purrs like a kitten. Only the other end of the
motor shaft dug a little divot into my table saw's side table. :-(
The name plate says DELTA MANUFACTURING COMPANY MILWAUKEE WISCONSIN USA
in a triangle, with the point down. DP 220 is in raised letters on the
side of the casting. The motor is a 1/3rd HP Induction Repulsion motor.
Seems to be in good shape, but there's a little lash in the quill's 3"
throw. Turning the handle moves the pointer 1/8th inch, but the quill
itself doesn't move. My dad suggested the machine was bought in the
1930s, and it has a sticker listing patents that protect it; the newest
one is from 1935. The photos on owwm.com suggest this is a 1940s logo
(i.e. could be the same logo as this one, identified as "1940s"
http://owwm.com/PhotoIndex/detail.asp?id55 , and
definitely is not the same logo as the round red one on this drill
press, identified as a 1937:
I need to put this on a mobile base, and make a fence for it. But it's
