the same issue regarding motor size.? I'm not an expert by any
means but I'll share my opinion for what it's worth.
I own two lathes, a Clausing 12x36
model 111 late 1940's lathe and a Dalton B-4.? When I purchased
the Clausing it came with a 3 phase 1hp motor and two broken bull
gears.? When I restored the lathe I looked at the original
literature which called for a 1/3hp motor.? That's what I put on
it and it works just fine.? Now, if a 12x36 lathe called for 1/3
hp then a Dalton which is much smaller should be fine with 1/4. In
fact that's what I put on my Dalton and so far I am well
satisfied.? Perhaps you can't take as meaty a cut but you won't
break anything either.? You said the motor you have draws 5.8
amps.? I believe a 1/2 hp motor draws about 4.2 amps so that motor
may be bigger than you think it is.
As far as a period correct engine goes
there is something to consider.? I bought an old 1930's cylinder
honing machine at an antique shop just to get the motor.? It was a
'Sunlite' 1/4 hp motor and after a bit of cleanup it ran just
fine.? However, this motor did not offer access to the start
winding.? The start and run windings were tied together deep
inside the housing.? This means it would be difficult to make it
reversible.? I don't know when single phase motors began using
start windings that could be easily reversed to change motor
rotation but you would want a motor that could be easily reversed,
especially if you want to cut threads and don't have a thread
dial.

My lot 5 came with a late 60s/early 70s GE 1/2hp 1725 rpm motor.? Think it's probably well suited functionally but I'd like something a little older in keeping with the style of this old girl.
