    Rockwell 12-14 Table Saw Value

    I have a chance to pick up a 12-14 but have no idea what the value is. Looks to be in working condition. Three phase, 5 or 7.5 motor. (can't find a info plate but it is BIG ) I have a 3 hp TEFC motor, 1 phase that I could put on it. Would that be enough motor for 12 or 14 inch blades? Thank for your input on these questions.

    Depending on condition, 1000-2000 but closer to the bottom unless a really good fence, a couple of blades, miter gauge, etc. Then towards the top. Keep the motor and buy a vfd. $400-500 and you are good to go with full power and likely a very good motor. Those saws new were several times the price of a Unisaw and several times the build. They tend to sell for short money due to size and phase but well worth the top end of my range. Dave

    I just paid $600 for mine. It was in very good condition having been rebuilt by a prior owner. Be aware that the pulley can not be replaced for a reasonable cost. if you change the motor you will need the correct frame size (182T, 184T or 213T), shaft size and speed. I tried to replace my motor and after buying two that were incorrect, I gave up and went with a VFD. There are some 1ph input 3hp VFD's out there. 5hp is tough to find and 7.5hp is unobtainable. What I found is that you can use a 3ph input VFD and supply it with 1ph power. The VFD will need to be derated when you do this. Generally you'll lose 50% of the output, but verify this with the manufacturer. In my case I'm using a 10hp vfd that would support a 5hp motor. Now some will put a larger motor on the vfd and use it's built in limits to protect the unit. For example, they'll run a 5hp motor on a 3hp vfd or a 7.5hp motor on a 5hp vfd.

    Jack Forsberg, who frequents the Canadian Woodworking forum, sells VFDs with single-phase input up to 15hp. I've never dealt with him, but I frequently hear him mentioned as the go-to guy for larger VFDs. The miter gauge slot on a Rockwell 12-14 is larger than the standard slots in 10" saws. So you'll want to either make sure the saw includes the miter gauge, or see if there's an after-market one available to fit it.

    Jack does a good job with the vfds . Miter guage is rare and goes for about 150 as a used accessory. Dave

    How much are they asking for the saw, and what kind of shape is it in?

    If it has a 5 HP 3 phase motor you can run it just fine with a TECO FM50 3 HP VFD. I've been running my saw like this for over ten years with no problem. Yes, it does derate the motor, but then again, I'm not ripping railroad ties all day long, either.

    The main advantage of the 12/14 saw isn't necessarily the size of the motor. The saw was marketed to school industrial arts departments, cabinet shops and "light industrial" use, where most of the material being cut ran from sheet stock to 4/4-8/4 material. The big advantage is the size of the table, making it much easier to break down sheet goods than using a regular 10" saw. This was long before euro sliders (or tracksaws) were around.

    Two on my local Craigs List. A 12/14 for $2k, and an RE-35 with factory sliding table for $3500. Both 3 phase, and the slider looks really clean.

    Well, first off, thanks for your replies fellas. The old saw is still under a lot of stuff at the estate sale so really don't know lots about it. Can't get down and look under the motor for a tag. None showing from the little I can see from above. Has the original fence and miter gauge.Will be going after it Mon. morning. Bought a Delta 14" band saw and an OLD Delta scroll saw that must have a 24" cut all at the same time. Price was reasonable is all I will say about that. Will let you know how it all shakes out when I get it home.

    What is so special about that pulley? Modern Vee belts can handle 7hp with a single belt these days.
