Removing Rubber from Old Rims.....

[Nick Goodall]

I've got to the point that i'm nearly out of B3 rims and rather then having to find any on Ebay etc, does anyone know of an easy way to get Tyres or just scraps of rubber from old rims?

I must have 100 sets with knackered tyres on so would really love to be able to use them again (including the Foams)!

In the old days we would boil them for a while in a pan, then pull off as much of the tyre as possible but would still have to file away the small bits of rubber left on the rim which took ages.... surely there must be an easier way??

Look forward to hearing what you all suggest....

Thanks.

acetone. - get a sealed tupperware type container that you can lock the lid on and get a air tight seal. works great.

Hey Jimmy, where can i get acetone? Also, do you have to completely submerge the rims, or just cover them in it?? How long do you need to leave etc, and do they just pull off after?

[jimmy]

you can have the acetone a couple of mm deep if you want and do one side at a time. or totally submerge them. I think you MIGHT even be able to get them off with just the fumes but that might take weeks!

they will just pull off with no effort..
Yellow and blue schumachers dont get damaged by it, greens do if you leave them in too long (they go hard).
Foams in my experience don't really get effected (the foams I use) people tend to claim they do - but these people don't get all the acetone (and glue) out of the foams, they need to be totally wringed out. or even washed in some clean acetone after..
The thing that ruins foams is washing them whilst they have the aceton/glue still on them. the water hardens the disolved glue. they do baloon up larger than normal in aceton but shrink back down when dry.

a veg steamer the ones with timer are also spot on

i agree with jimmy use acetone

I would normally cut the tires off jeaving jst the beading pull the foam off meaning more wheels can go in at once. leave them there overnight and the left over tire falls off.

the only time i put the whole tire in is if its worth saving normally when the foam has split otherwise the tires are normally shot and not worth saving

Acetone is a mild carcinogen, I found out a couple of months ago after 8 years of contact.

been banned @ work for ages on the refinery for almost 15 years now due to the the above.

but it can still be had if you know the right people @ work

Nick, I've used acetone on genuine B3 rims before with no probs. It was tesco value nail varnish remover though (cheapest I could find) Takes approx 2 days to remove the glue with the majority of the tyre cut off. Highly recomended

Not wishing to bore anyone but i would strongly recommend viewing the material safety data sheet on this chemical (Google, msds acetone) Although it does not appear to be listed as a known or anticipated carsinogen it can be extremely hazardous if not handled correctly.
As an overview it is an extremely flammable liquid & vapour, the vapour can cause flash fire (sensitive to static discharge) Harmful if swallowed or inhaled, causes irritation to the respitory tract and effects the nervous system.
Use only in a well ventilated area, pref outside, away from ANY source of ignition & wear gloves (not winter wooly ones) & safety goggles. t is a skin irritant and splashes to the eye can cause corneal damage. Prolonged exposure can result in liver damage.
Sorry to go on but as i am employed as a H&S engineer feeling a bit guilty as i posted where it can be obtained from. (beauty wholesalers will sell the real Mcoy if asked for)
