I recently acquired an older Diamond Star 10" slab saw that has been sitting in a hot garage for 20 years. This saw is the precursor to the PF10 by Barranca Diamond. There is a 3 way toggle switch wired to a plug on one side and the power feed motor on the other side. The power feed motor wasn't turning, so I took everything apart, unpluged and separated all the wires from all of the components and now have the motor gears soaking in dish soap (the old grease had become solid, not allowing the gears to turn). But now I have no idea how to rewire everything back together properly! Is anyone familiar with how to rewire this and can walk me through it? I'll be replacing the power cable as well. I found the manual for the saw: www.barrancadiamond.com/pdf/manuals/lap/pf10_manual.pdf, but there's no diagram of how to do the wiring...

You will find the answer at the top of page 11 of the PDF you linked to (BTW you have to remove the comma at the end of the link to get there) It's not a wiring diagram but it explains the switch positions. A 3 position switch is simple to wire. Hook your supply to the center pole, then thw things you want to power need to be attached to the opposite pole from the switch direction you want to use to connect it. From your description it sounds like the blade motor wasn't wired in? Or does your switch box have a power plug on it to plug the blade motor into like a Raytech?

Does the switch have six terminals?

Lee,
The switch box has a power plug that the blade motor plugs into. I'll take some pictures tonight, that might help.
Par, yes the switch has 6 terminals, but no indication as to which wire goes where so far as I can see.
Thanks!

Don – It’s a double pole double throw switch.

The now discontinued PF10 had a 2 pole, double throw switch. Like Lee said switches opposite handle. Imagine the toggle handle as a lever. Throw switch to left, other end movers right. One position connected to blade motor, other position to blade and power feed, center off. Assuming standard cord, wire incoming black to both center terminals of switch. Wire white incoming to white to power feed and white to blade motor (or neutral terminal if a receptacle or female plug). They used a double throw switch to enable manual cutting/trimming without power feed running. Connect green ground wires to ground screws or box screws. If I remember the BD version switch went toward operator for manual cutting, in direction of feed for power feed.

On my Star Diamond, the switch goes toward the operator (away from blade) for power feed because there is a linkage that pulls the switch forward to turn off the saw at the end of a cut.
If you're not able to get it wired let me know and I'll try to get a pic of the inside of my power feed box. It might take a few days, though.

Chuck is right about direction. Auto shut off would not work as my fuzzy memory described. How old is the Star Diamond? The originals had vise on right then changed later to left of blade.

Thanks for the help guys. I need to study up on my basic electrical wiring.
John, The vise setup looks identical to the PF10 photos. If it's been discontinued does that mean the parts are cheap...?...hmm....

Ok, I've got something wrong here. I have 2 black wires coming out of the power feed motor, a black, white and green coming from the power cable, and a black, yellow and green coming from the power outlet that the blade motor plugs into. I had all the black wires twisted together and all the white wires together with the green grounds attached to a screw on the motor casing but when I powered everything up, the circuit breaker went off.

I've started over, here's what I have now:

If the power feed motor has two black wires hook one to the switch. The other (if one is ribbed use it) hooks to the white from power cord. Power cord white, motor outlet neutral (check the outlet wiring) and ribbed power feed wire all wire nut together. Switch center hook up to power cord black (jumper to both terminals). Motor black to each side of switch outer terminals, power feed "black" to one outer terminal. Hope this makes sense.

Thanks John. I got it sorted out last night, turns out my switch was bad as well. So after replacing it and re-wiring everything my saw is up and running again! yay!

The manufacturers tended to use barely adequate switches in lap equipment. I like to use at least 15 amp switches for everything, larger on 1+hp motors.
