Hello everyone and thanks for taking the time to read this!
I’ve been getting setup with a few tools to make some speaker boxes and take care of some projects around the house. Craigslist has been a great resource for quality tools when you know what to look for, but sometimes the best deals come with a few repairs to be done.
I started with a Delta 34-670 I got for $50. I replaced the ribbed belt and gave it a through cleaning, lube and tune up. It turned out to be a great bench top saw, but it’s loud, small, has a universal motor which I fear won’t last too long and the fence leaves A LOT to be desired.
Recently I found a 34-410 contractor’s saw for the same price and I intend to fix this up and sell off the smaller saw to recoup some $. The issues it has are the arbor bearings (I understand this is a common problem and relatively easy to fix) as well as some motor problems (maybe).
The problems with the motor are:
1. The pulley won’t stay straight when I tighten down the setscrew. It seems to push it out of true by about 1/16”. Both pulley’s were replaced with browning cast iron pulleys by the previous owner.
2. The same thing happens with the setscrew on the motor’s fan. It also goes out of alignment when tightening the setscrew.
3. The motor makes a hissing noise when it comes close to stopping, I think this may be part of the starting mechanism but I’d like to hear more opinions.
4. The bearings seem to be making a bit of noise. I took it apart to check and while they aren’t “bad” they don’t seem to spin like new bearings should.
What would you all suggest? I haven’t used one of these since HS wood shop so I don’t know if I should be worrying. Is this small amount of run-out on the motor pulley an issue? It’s not vibrating badly, but I don’t want to have the motor break because I ignored the problems. I think right now my options are to run it as is and hope it last a while, buy a pulley set and new motor bearings and try to fix it myself, or take it to a repair center if these problems need to be corrected. A new motor is a little out of my budget right now and would cost 6 times what I paid for the saw.
