I want to rewire an old Craftsman table saw motor

[dpantle]

Hello,

I'm new to wood working, and just inherited a vintage table saw from my Father in Law. It has a motor on it which is a 115/230V that is currently wired for 230V. I don't have a 230V circuit in my garage to handle it, so I would like to rewire to 115V.

I opened the terminal cover in hopes of finding wiring instructions, and the only thing I can find is a diagram for reversing the motion. Needless to say, I can't find a manual for the motor, and haven't been able to source one through Sears or internet sites such as vintage machinery.org.

The model number is 115.19250, and it's a 115/230V 1hp capacitor start type. Does anyone here have any ideas where I could find a wiring guide, or know which winding terminals I would move?

Hi, could you post the diagram you have?

Thanks, Rod.

Here's the label underneath the terminal cover. i really appreciate any help here.

Oh boy! I just looked a little closer to the diagram once I uploaded it. I guess I just move the jumpers from 2>3 to 2>1 and 3>4, correct?

Remove the jumpers between 2 and 3. Put one jumper between 1 and 2 and put the other jumper between 3 and 4.
Connect 115V to 1 and 4.
Oh, unplug the saw first.

thats what it looks like to me

a couple of pics of before and after would be a good reference for others

how old is the saw?

[dpantle]

Sure, I'll do that tomorrow when I get back to it.

Believe the saw is mid-60's Craftsman 100 series. Nothing fancy, but more than adequate for a beginner such as myself.

Here's what it looks like before and after.

that's a nice setup for changing voltages, most are some combination of moving wires around

the old craftsman saws from the that era are far better the "small" saws available today, they have quite a following on owwm.org

my shop and worktruck are both equipped with old beavers from the late 40's, there's nothing wrong with old equipment

[dpantle]

Yeah, I was expecting to swap winding leads, and was glad to see that jumper setup.

I was really happy my FIL gave me this unit (as well as quite a few more older power tools). I had to drag this stuff more than a thousand miles back home, but it was well worth the trip. I totally agree that older tools are of far better quality than the Chinese made junk that's out there today. The fact that it can last 50 years and be as functional as the day it was built says a lot about the quality of build.

you should post a couple of pics of the old stuff in the powertools section, there's quite a few old tool nuts on here and craftsman stuff is not nearly as common here as it is stateside

there's also tons of info and stuff on vintage machinery, well worth checking out
