Craftsman industrial not getting up to speed

[Jan-willem]

Need some help with getting my lathe set up
Just bought a craftsman industrial 12” with qcgb and super happy with it.
the previous owner had put a 20a 110v connector to a very short lead out the motor. But the drum switch was not connected. the motor runs but the lathe is not coming up to speed and in high speed it has no power. Could it be that it needs to be hooked up on 220v?

Indeed, that is what it sounds like ---

How would I know?

Any time you have the chance to use 220v vs. 110v you should. Since it's a Dayton motor there should be a reference somewhere online to confirm the hand written note.

Welcome to the forum, this is definitely the place to ask this and any other questions you have.

They usually have a wiring diagram on the nameplate showing the connections for high and low voltages. Sometimes it was a paper diagram pasted inside the wiring box cover. That motor really looks nasty with all the corrosion inside and out; think about replacing it. One thing, is that the centrifugal starting switch inside the motor could have corroded points, this could effect the starting of the motor, but from your description, it sounds like it is wired for high volts.

No there are no diagrams. What is the best place to get a new motor from? And what hp rating should I get?

I bought a Baldor 3-phase motor and a Teco VFD for my Seneca Falls Star lathe and couldn't be happier. With the VFD you can adjust motor speed with a knob which is very helpful if you're lazy like me and don't want to look up what speed/feed you should be using.

There are plenty of surplus houses that deal in this stuff plus eBay of course. Lots of info on the forum about it too.

Cheers,

Thank you. I will check on that.

Try googling dayton 5K318D wiring diagram. Lots of references online. Rewire it for 115v.

how much power difference is there with the 110 v vs the 220v?
