    Unhappy Don't install RUBBER bandsaw tires this way......

    Well, I finally got round to putting the rubber bandsaw tires on the Phoenix, or I should say I "Tried" to install them.......

    I followed the instructions that came with the tires, I cleaned the rims of the wheels REALLY good with Lacquer Thinner, just like it says.........

    Once I had the rims really clean, I stretched the tires on, then I put a 1" diameter steel rod between the wheel rim and the tire........
    Attachment 10909

    I got the glue ready, with some rubber gloves.........
    Attachment 10908

    I made up an applicator and put some glue on it, and proceeded to spread the glue as the instructions state, on the tire and the rim...........
    Attachment 10910
    ..messy job. After I'd done that, I had a fair bit of squeeze out on the rims, and as the glue is this black sticky stuff, I thought it would be a good idea to clean the glue up, while it was still somewhat wet, so I got out the lacquer thinner again and cleaned things up................ BIG MISTAKE

    I left the wheels with the newly installed tires on them for about 40 hours, as I was busy doing other stuff.

    Tonight I tried to "Crown" the wheels, but they had turned to sponge

    They would not sand, I tired, I was using some #80 paper, then some #120, no change, the tires are S-O-F-T

    Attachment 10914
    They are now sticking out over the rims in several spots, and to show you HOW soft..........

    Attachment 10915

    That soft.........bad words were said, lots of them

    Attachment 10916
    The tires were 1" and 1" is 25.4 mm, so they should have fit just fine.

    Oh, this is the way I drove the top wheel to try sanding it.........
    Attachment 10911
    .....this worked well, too bad I was trying to sand sticky sponge. Several times the wheel would grab the sanding block and whip it out of my hands......

    I'm don't know who to blame for this, they say in the instructions to use the Lacquer thinner to clean the tires too, but I'm of the opinion that the Lacquer thinner is what made my tires go all sponge like........... What woud you guys do........

    Boy I feel Stu-pid tonight

    Oh well, time for bed

    Well they have been removed, and pitched into the corner bin.

    They say the tires are 20% smaller than the wheels, and they were new, but now, tugged off the wheels they are bigger than the wheels

    Back to the 1/4" wide strip of tape on the center of the wheel and the urethane tires

    Sheesh, that's UGLY!

    Are those the ones I recently forwarded to you Stu? Can you send the seller these pics and ask..."what the hey"!

    I was thinking of getting some for my saw, but now.....

    geez, I hate it when that kind of thing happens. You have my entire sympathies.

    My band saw's still broken... the part isn't in stock. I'm using it anyway, but it makes me mad each time I use it...

    Thanks,

    Bill

    That stinks Stu! It looks like the adhesive attacked it - I don't think wiping it with lacquer thinner would have softened the entire tire. Maybe the surface, but not all of the way through. But having the adhesive in contact over time could soften the tire. Either way it sucks - to put it bluntly. The adhesive that recommended to me was a yellow almost contact cement like, FWIW.

    My sympathies,
    Wes

    Stu, I don't have a "definite" answer to your problem, but the adhesive shown in your pic looks like the same kind of adhesive that is used to install windshields in cars. If so, it is basically a liquid rubber, and when dry acts and feels like regular rubber. When we had windshields installed in vehicles (in the car business) they asked us to keep ANYTHING liquid off of it for 24 hrs, and if there was any excess that needed to be trimmed or cleaned off after that time period, we used a razor blade to trim it off. A lot of rubber products do not like Laquer thinner and will soften and swell after contact with Laq Thn, but if you "Must" clean rubber with laquer thinner to get wax or oils off, the rag should only be damp and make a FAST pass over the rubber with it, never let the liquid get on the rubber.

    My suggestions, (if you try to do it again), are as follows; Install the tire on the wheel, then use electrical tape and stretch it around the wheel so it laps over just enough to cover the outer faces AND the thin edges of the wheel, then slip your rod in place between the tire and wheel. Now, punch a small hole in the SIDE of the applicator tip, (instead of the end) and then squeeze a small bead onto the "center" of the wheel under the tire. Don't worry about trying to get it on the tire, because as you work your way around the wheel, the tire will press down on the adhesive bead and spread it across the wheel AND the tire. DO NOT clean anything until it has completely dried up and SET, except for excess adhesive on the tire and then only use a dry cloth, (you will remove any other when you sand it to crown the tire). After it has cured, you can then take a razor blade and make a slit between the tire and wheel's rim and this will let you peel off the electrical tape and any adhesive that has squeezed out on top of it, and it will give you a nice clean edge and finish. Try to work around the wheel as quickly as possible so the adhesive doesn't have time to "Skim" over or be disturbed after the contact of wheel and tire is made.

    Good Luck, and hope this helps.

    (I know you had to be MIGHTY frustrated when that happened).

    I would certainly agree with you, Steve. If the new tires are the proper size, they should be more than tight enough to hold them in place and work properly. The only way I would ever use adhesive is if I had an old set that had "Loosened up", and couldn't get new ones for a while. (Besides, I'm not as energetic in my old age, and getting kinda lazy in that respect and wouldn't want the hassle of getting them off again later and cleaning up all that old adhesive).
