Topic tags/keywords: band saw tire fly off bandsaw shred bandsaw tire fly off band saw shread bandsaw

Hello, need help with a reoccurring problem I’m having with my Laguna Tools LT18 3000 Series Bandsaw.

I’ve recently replaced both tires on my 18”, 8 year old band saw, the bottom drive tire more than once. Each time I replaced the tire I tried using a different adhesive and meticulously set up the blade to track in the center of each tire using the specific # of tension for the blade prior to setting up the upper and lower guides. I cleaned each wheel carefully with a wire brush and acetone after each failure. Tried using both a 1” re-saw blade as well as a 3/8” blade, am getting the same result. Also tried both urethane and rubber tires, each time it took a tremendous effort to wrap the tire around the wheel (soaked in hot water prior to wrestling it on). With that much pressure around the wheel, seems like cement wouldn’t even be needed!

My last effort I used what appears to be a quality rubber tire replacement from Woodworkers’ Tool Works. They recommended an industrial high tack rubber cement, Fastik to bond the tire to the wheel which I did. I let the glue cure for a week while I was on vacation before I turned the saw back on. Again set the alignment up carefully and ran the saw for 5 minutes without issue before I pushed any wood into the blade. I re-sawed one 5-1/2” tall board and started on a second one when the new tire blew up. I’ve also tried using Barge Cement with no success.

I’ve got a fair amount of experience with setting up band saws and other equipment to run well, this has got me stumped. What would make a new tire with adhesive come off? The machine does not vibrate and the wheel bearings feel pretty tight with little play. Any help would be appreciated!

Are your hearing any slap or ticking before the tire goes kaplooey? The glue is failing and quickly. Heat is the enemy of glue. Since you’ve tried 2 different glues, it would seem like something is putting extreme pressure on the tire causing heat build up quickly; and that would have to be the blade, I would think.

So you are saying that the tire basically is thrown off of the wheel?
What happens to the blade?
Is it only the drive wheel that fails?
Is the tire cut, then thrown or does it just come off in one piece?

One thing that could be happening is blade tension is too low, those factory built in gauges are usually incorrect and read low (very low).

Best bet is to tension the blade by ear/deflection measurement/tension gauge.

Another thing to look at is what the wheels do when you have it all set up and ready for a cut. Spin the wheel by hand and see if the blade starts to wander or if something is contacting the tire.

Most places recommend 3M 1300 adhesive. I’ve also seen people use epoxy as well as 3M 5200, but those are a beast to remove if you need to replace the tire again.

Cheers,

I used 3M 77 on mine, time will tell if it is good enough.

I had to retire a Laguna bandsaw.It took several attempts to get the tires to bond with the wheel I think it was epoxy.
But the saw ran like poop it threw the wheels way out of balance. Think I went thru three sets of tires plus glue.Very expensive lesson.
So I gave up and brought the wheels over to Dailey saw service in south gate.
There I met a friendly old timer that told me nicely in aloud voice you just can’t put tires on and Hope for the best.
They did a fine job of crowning and Turing the tires to run perfect with the center if the wheel.
The saw ran better then new.

Not hearing anything before the tire hits the fan. Only one board through the saw before it shreds wouldn’t be too much heat I would think.

Could be tension, will check. By the gauge on the saw, I dialed up 1/2” tension for the 3/8” blade, a little over 1” tension for the 1” blade thinking a little more = better than not enough….

Also, the tires were more-or-less shredded into relatively small pieces, not much left.

Thanks AJ, do you mind if I ask what did the cost of the crowning/turning cost? Was it tough to take the wheels off of the band saw?

Taking the wheels off isn’t that hard.
I remember Dailey saw offered two different tire options one was Vulcanizing or rubber glue on.I chose the rubber.
You’ll have to call them for a quote.I only remember 125 but that might have been per wheel.Its been too long.
Good luck.

Actually less tension is better then more as long as the blade tracks straight when cutting. BUT there are so many facts and opinions out there on that and how to set tension. I go by the 1/8” diffraction over 6”, and then adjust a titch either way as needed.

When you put the new tires on… did you crown them?!?

Did not crown the tires, there is a slight rise in the middle of each wheel on the saw, no evidence of needing to crown the tire in the owners manual. By crowning the tire, what do you mean?

Thanks for your help!

If you can find a rubber company that does Vulcanizing, go that route. I had my bandsaw tires done back in 1983-4, and I haven’t had any problems since. .................. Jerry (in Tucson)

personally I do not think it is tires at all ….. look for other problems with saw …... ie: bearings ,guides ,all moving parts
