picked up an older Unisaw a few months back and have just had the chance to start cleaning it up an tuning it up. Had a couple of questions since this is the first time I have attempted this.
1. My pulleys are close to a 1/4″ out of alignment (pic1), best I could tell to re-align them I need to loosen the set screws that hold the motor pulley in place, re-align and re-tighten…. these set screws are located in the “valley” of the pulley (pic 2). My concern here is the motor pulley is already flush with the outside edge of the shaft. Is there another way I should be approaching this?
2. The motor is currently set up for 220V – I believe this can be changed to run on 110. Is there any downside to switching this? I have the saw set up in my house at the moment while I am doing my kitchen renovation and since my electrical skills are somewhat limited I thought changing the motor would be easier then getting 220 service to the saw. Any thoughts or advice? Attached a pic of the motor details in case that is helpful.
Thanks,
Sean

Looks like the wiring diagram is right there on the motor ,just take the cover off where the power cord goes in and the connections are right there , you will need a dedicated 20 amp circuit to run on 115 v. I'd put a blade in it and see if it viberats to much before I muck around with the pulleys, it might just run fine the belts are probably worn to the misalignment.
My unisaw is my favorite tool of alltime
good luck

You may already have 220 somewhere close. Do you have an electric range or electric oven hook up in the kitchen? Is there a electric dryer hookup close by?
thanks for the replies -- much of my electric has been demo-ed already including the old dryer hook-ups, if I recall they weren't 220 though. I guess I could have the electricians set a line up for me, I will eventually be putting one in the garage/shop.Rik -- I tend to be an "if it ain't broke don't fix it" kinda guy so I think I'll take your advice and leave well enough alone until I get the saw up and running and see what it sounds like then.thanks
Consider picking up a copy of "Care and Repair of Shop Machines" by John White, who I believe is the Fine Woodworking shop guy. Easy to understand without leaving things out - great for tuning up or refurbushing old machines. I took a $100 Ebay Delta joiner and turned it into a great machine with the help of this book. http://www.amazon.com/gp/product/156158424X
Consider that at 110/19.2 amps you'll be pushing the limits of even a short dedicated 20A circuit (which you probably don't have in the old kitchen anyway), but at 220/9.6 you'll have plenty of margin of error.
Some places require a 220 in the kitchen eventually anyhow.
I've been told saws 'run better' on 220, though I don't know how much of that is the 220 and how much of that is the better saws that can run on 220.
