Just moved to the San Fran Bay area and the movers didn’t crate or even really secure my band saw. Parts fell out all over the place. It’s not really broken, it’s disassembled by vibration. the upper wheel tensioner assembly is not at all assembled any more. If I could figure out how to compress the coil spring and still get the parts in place I’d take a shot at it my self but I haven’t been able to figure it out. Does anyone know a tool repair person near San Francisco they would trust to fix a Griz 17” Polar Bear band saw?

Can you compress the spring in a vise then hold it in compression with some small gauge wire to get it in place then cut and remove the wire to release compression?

I bet you could find an on line parts breakdown for this saw and assemble it yourself.

Head over to OWWM, there’s probably some old arn heads over there who would be willing to help you put it back together. It’s a simple mechanical process. Compared to the old stuff they do, a modern, fully documented project should be a piece of cake for them.

Don’t even think about compressing a spring in a vise!
That’s a segway for injury or worse when the spring breaks loose and flys like a bullet.

Only way I can think to safely compress a spring like that in your own shop is to put a high grade threaded bolt and nut in the middle and compress. But it doesn’t help on how you get it back in the setup on the saw. I own that saw, and I would hate to have to try and compress that.
I’d be taking it to a machine shop to let them reassemble.

How about contacting Grizzly and asking them for advice. I am certain that they know how to do it.

The first step you should have done is contact grizzly. They should be able to help you with that.

Wow, a bunch of negative Nancys!

TO compress the spring grab 2 chunks of steel plate, about 3/16 – 1/8” thick.
Drill a hole slightly smaller than the ID of the spring. put your spring centered over the holes with a piece of steel on each end then put a full thread bolt through the holes and the spring.
Cut a slot from the end of the steel to the hole that will allow the clamp to be removed.
Compress the spring by tightening a nut down on the bolt you installed in the previous step.

When the bolt is compressed put a good clamp on each side and tighten them down. If a C clamp will work, use it, If you need to find another type of clamp, do that.
If you cannot find a clamp that works, just wrap baling wire around each end of the clamp many, many, many, many times.
Remove the bolt in the center, very carefully, and be ready to flee the scene. (I use angle iron when I’ve had to do something like this, it’s a bit of side protection).
Now that the spring is compressed, the bolt is removed, put the spring in place and cut the wire after you put the knob back on.
Remove the steel plates and Waa-Laa you have just completed your fix.

I probably forgot something here, but it’s really a simple process that anyone with an IQ and common sense above that of blade of grass should be able to accomplish with no problem.

More than likely, doing that will get you tarred and feathered as they prohibit the discussion of anything other than vintage american made machinery.

Post a picture.. without seeing what you are talking about (and not having that particular saw), it’s hard to imagine why it would be so difficult to put a tension spring back in place.

Either your not making sense or your on Wackey weed.
You said “compress the bolt?”
Maybe “compress the spring?”
Then it gets even more weird after that.

Dallas’ solution may work. Even if he is a dick about it. An auto parts store might rent you a variety of spring compression tools.

Gee, sorry I mentioned anything.

I have noticed many mistakes in writing on this board but never mentioned it. Tell me JimC, why wouldn’t this work?

TheFridge, in what way am I being a ‘dick’ about it? I gave instructions, albeit, with a mistake that should be easily figured out.

I did not insult anyone, I did not condemn anyone and I did not mention your name in anyway when I spoke of a blade of grass.

Please tell me how I am wrong in this assessment of the abilities needed to accomplish this task, although it seems that jim C may not come up to those standards as he also took umbrage to the statement.

Dallas my friend, do not rise to the bait. There are those who have nothing better to do than troll looking for any excuse to insult and condemn others. I have noticed that they rarely offer constructive advice but are quick with their superiority in all issues. Never apologize or respond to these holier than thou anal sphincters, they are not worth your attention or time. If they do not get the attention they crave they eventually take their attitude elsewhere and avoid the pain of being a nobody in a group of friends. I have a degree in English and yet I am prone to spelling and grammatical errors just as much as the next person. The fact is that I was attuned to your explanation and had to go back and search for the word usage error in your post. I do completely comprehend your concept for compressing the spring so maybe I am also as ignorant as a sack of rocks. Illegitimi noncarborundum! ( Don’t let the bastards grind you down)

mudflap4869, Thanks, I let my self respond too quickly. You are correct in your thoughts.

I usually take more time, especially because I do pride myself on my writing, syntax, sentence structure and word usage abilities.

My mother was a tough task master and would have done a Jethro Gibs to the back of my poor innocent noggin if she had seen that faux pas.

For about a year during my college time I did proof reading for the local newspapers. I was promoted to teaching the incoming interns and employees how to watch for mistakes. A dubious honor at best. I am just glad I don’t have to do it nowadays. Spelling, as well as sentence structure and the basic tenets of journalism is atrocious!
