After you do the straight edge thing most of your bearing problems will be resolved. To adjust the upper wheel, grasp the top with one hand and the bottom with the other. Then push the top and pull the bottom. What you are doing is straightening the tension arm back to it's original place. DO THIS TWISTING GENTLY!!!!!!! Too much is bad.
The arm has gotten in bad shape (twisted) from leaving tension on a blade for too long of a time. It is best to not over tighten blades and to relieve tension once you are through sawing. At one time we were cautioned by Nick Engler that the more often we do the bending of the arm, it will lose it's stability. So hopefully you only have to do this once. Relieving tension when the bandsaw is not in use is the best procedure to preserve the tension arm.

I knew it was something along these lines in solving the problem. And, yes, there was a "reminder" in the adjusting instructions, about loosening the tension after each use so as not to "set" the blade and wheel...this tire is showing an impreesion in the original tire material, where the blade has "set". I'm attempting to upgrade it with urethane tires, but first have to get the "bugs" worked out...again, these suggestions have been very helpful in me making my adjustments, and I thank everyone for the info...
I can't get back to the saw until a couple of days from now, but at least with the information I've gathered here I now have a "fighting-chance" at working through the problems...

Blues revisited...
It is July 20th, 2013...and it's 11:48 p.m...and I have just finished my rebuild of my band saw. I will attempt some picture during the "test-run" tomorrow.
I replaced the tires, bought and placed, a "new" 1/2" band saw blade, tensioned everything and worked mechanisms by hand, rolling over-and-over approximately 25-30 turns, watching for any slight problems...and guess what? the blade is actually following the roller bearings, LIKE IT'S SUPPOSED TO !!!...hurray for me !!!
Like I said, I'll show some pictures tomorrow and I'll want some opinions, okay?
Did anybody else think that replacing the "old" tires with the "new" tires was a real "pain" job????...the old tires were a bitch to get off.

I visualize that would indeed be the case!:eek:
THAT is why I have not done so even though considerable cracking etc. is evident on the 'older' one.

A caveat here!
Adjusting(bending) the arm this way runs the risk of warping(bending) the wheel.
Our resident guru(Bill Mayo) recommends applying torque to the arm by placing a pipe over the shaft and pushing up on the end of the pipe while holding the arm in place(pulling down). That will be my method in the future!

Yes, removing the old tires is a job that I did not enjoy, particularly getting all the little scraps of rubber and glue off. In the end I put a flap sander on the quill, took the wheels off and flap sanded off the glue/rubber bits. As bad as that job was, getting the new orange silicone tires on was a frustrating struggle too. But once the job was done, I too found the blade tracking better in the auto track bearing groove.jtevans wrote:It is July 20th, 2013...and it's 11:48 p.m...and I have just finished my rebuild of my band saw.

It looks good from the camera angle, but the upper guide backup bearing should barely CLEAR the back of the blade, and only contact it under cutting pressure.
Interesting tire 'color'.

tire color...
Tires are from a company that supposedly makes these "exclusively", found the link on Ebay. I'm attaching a copy of the ad where I bought them...JPG40504 wrote:It looks good from the camera angle, but the upper guide backup bearing should barely CLEAR the back of the blade, and only contact it under cutting pressure.

Brand new set of 2 BLUE MAX Heavy duty urethane band saw tires to fit Shopsmith and Magna band saws.
Our Blue Max Brand Urethane Band Saw Tires are the newest and most advanced band saw tires available.
After years of testing we developed our own formula to make Blue Max urethane specifically for band saw tire use. Blue Max tires will outperform and outlast the standard conveyor belt orange urethane everybody used in the past to make band saw tires. We have formulated the Blue Max urethane to last year’s longer and the surface finish of Blue Max urethane was designed to repel even more saw dust then the orange conveyor belt urethane that was not specifically designed for use as band saw tires. Blue max tires are not affected by freezing temps for those of you who may run your band saw in an unheated garage or shed.
Blue Max band saw tires are a registered trademark of the Band Saw Tire Warehouse and only available from us.
Made in the USA. LIFETIME WARRANTY!!!
Consistent .095 thicknesses across the entire width of the tire for precise blade tracking...
Update your band saw with a set of new urethane tires. No messy glue needed.
No need to damage your wheels with a screwdriver trying to stretch them on.. We include a custom installation tool and instructions with every set so you can mount the tires without removal of the wheels from you band saw and without damaging your wheels.
Our free lifetime warranty is the best in the industry. If your set of Blue Max band saw tires ever just send them back to Band Saw Tire Warehouse for a free replacement. Regardless if you purchased them from us or one of our many distributors. We are the ONLY mfg. making Blue Max tires so no receipt or proof of purchase is needed.
