So a little over a year ago I replaced the old rubber tires in my bandsaw (NIC brand, same as the Grizzly G1019 and HF’s 14” bandsaw) with new urethane tires. Well, the urethane tires are a little thinner than the rubber tires were, so that, coupled with the fact that the top wheel was routinely near its max vertical travel combined to make it so that the top wheel scrapes against the upper housing whenever I try to put enough tension on the blade. Granted, the spring is the original, 30 year old spring, but a blade of a given size requires the wheels to be separated by a certain amount to get a certain tension regardless. As far as I know, I have three options: 1) remove the upper arm and shim up a fraction of an inch, 2) grind down a little bit of the upper housing, and 3) just buy the 92 1/2” Olson blades. Number 3 is most decidedly the easiest, but I don’t want to be stuck buying an odd size that has limited width and tooth options. #2 seems kind of destructive and #1 seems to be the best long term solution.

I tried removing the upper arm last night and the bolt simply will not budge. I also noticed that the blade guard that runs on the left side of the wheels wouldn’t be long enough to support an extra 1/4” or so of height. I guess my real questions are:

1) Any tips on getting the bolt that holds the upper arm to the rest of the assembly loose? Should I look into a breaker bar with appropriate socket?

2) Any ideas on what I could do the either modify or replace the blade guard that would be too short if I do shim it? I have the possibility of using some simple sheet metals tools (brake, shear, etc.) to fabricate one, the issue I see there is I don’t have any welding equipment. This piece shouldn’t see a lot of stress, so could I just epoxy some aluminum tubing to it to slide over teh support bolt things?

I would love to shim this guy, so any advice or suggestions would be extremely helpful. Thanks in advance.

Impact wrench will break the most stubborn nuts loose, but make sure your’e goinig in the right direction. They have been known to break studs, bolts, etc, as well. DAMHIKT.

I think if you took a measurement with a flexible tape measure to have a few new blades made. I’m sure that would be better than shimmin, or grindin.. I think I’d start by gettin factory rubbers like cr1 said

Well, I ended up shimming it last night. It wasn’t very easy, but it is running so much better. I didn’t get the factory tires because I heard all the great things about the urethane tires, I just wasn’t aware that the saw was already almost out of travel. Oh well, it’s working better now. Now I just need me a new tensioning spring.
