I have a 1950's Unisaw with the oval cutout in the cabinet. It came
with a new motor and a dead 'old' motor. I've had the old motor rewound and bearings replaced, and am ready to install it. [Side story: when I went to pick up the old motor, I paid and the couter person rolled the motor out on a cart but said "want a minute, Mr. Jones (forgot the real name) wants to talk to you. So the older guy in the back who actually does the rewinding comes out--althogh he recognized it as coming from a Unisaw, apparently my motor was unusual enough that he wanted to see who had brought it in. He told me appreciatively "they don't make them like that anymore" and "it should last another fifty years now". Thought you guys would enjoy that.] So I'm trying to put the old motor back on, and the pin won't go in. When I got the saw, there was a bolt through the motor and carriage, but I dutifully replaced it with the 'correct' Delta pin. I put the motor down, and sure enough, although the pin is a snug fit in the carriage, it's too small for the holes in the brackets on the motor. I could try to find a smaller pin, but that would just be loose in the carriage. I think the easiest 'fix' would be to drill the holes in the motor brackets to fit the pin, but I thought I'd consult the wisdom of rec.woodworking before removing metal I can't easily put back... Anyone know if there's a difference between the pin diameter on the new versus old Unisaws? Also, my 'old' motor is missing the inspection caps and junction box cover, so if anyone has a set they'd like to sell, please email me. Thanks, Heath |

They told me that my 1 hp repulsion-induction motor would outwork any 1 1/2 hp capacitor start-induction run motor. Perhaps that is the case, but I will never get the chance to try a test. Jim |

Must be... ![]() Mayhaps the motor wasn't the actual motor from the saw itself if the pin fits the carriage but not the motor brackets? Although, I suppose they could have had a two-sized pin... Don't see a problem w/ the drill-out scenario assuming there will be enough material left after you do so. |

I have no problem drilling it and if I screwed up I just weld another piece and drill again. |
