Default Foam Donuts??? Did the Police eat them all?

Ok, only kidding about the Police eating all the donuts.

Does anyone sell foam donuts anymore? that is all we used to by and remount them to our wheels, can't seem to find them anymore. What is everyone doing with all there wheels, just tossing them out when the foam is gone? Not that i am a big tree hugger...but what a waste.

Thanks,

Scott

May be a bit of a waste; but I'd say most tire mfg. now have better gluing systems than the average individual can do by hand. Thus, the tires are more consistent and faster this way.

I do remember having the donuts, mounting them, truing them down and shaping them. Took a while, was messy and the glue-jigs weren't that great.

I'd also say for *most* folks, having a set of good wheels to put them on would be hard to find (at the club level). Since wrecks happen and the wheels get nicked/distorted.

Yeah, i agree about the glueing and truing...messy stuff. But, what about those with older RC cars...specifically any serpent using the OS1 wheels, i have been told by several people that the manufactures are discontinuing them.

some places still have them.. but the cost is too close to a new set with wheels IMO

I'm also running a 950R and figure it's only a matter of time before the supply of OS1 premounts dries up. I'd also be interested in donuts, since the wheels can still be had pretty cheaply. Worst case, I'll have to buy the tires premounted on the Kyosho/Mugen wheel, soak 'em in thinner to remove the rubber, and remount them on the correct wheels.....brings back some messy memories.

man, that sounds like a nightmare and a half.


I was thinking about buying a large sheet of foam rubber and using a hole-saw or something to make my own donuts.

Then selling them to people like us for an insane profit.

just kidding.

I don't think a normal hole saw would cut it, would need to be a really fine toothed one i wuld think. I think a normal one would really tear up the foam.

Yeah, i was thinking that if you could solidly hold a sheet of foam and use a new & sharp hole saw spinning in a drill press at pretty high RPM's.. if you drill down slowly, it would make a clean cut, but i honestly dont know i have never really cut foam before.

its really the ID that i would be worried about being cleanly cut as the out side dia i would turn in a lathe to get rid of any roughness or runout/true up

it seems like you could even stack layers of foam to make your own multi-ring donuts too.

So, if they still sell the wheels, why can't we buy donuts! I really don't even remember what brand we used to buy.

You need to look for a hole saw that has grit instead of teeth. It's what you would use on tile or plaster.

Default ........I miss the smell of nitro ( can't wait for spring )

Calandra (Team CRC) should sell donuts (medium shore std rubber). With my ol' ReflexNT , I had attempted to experiment (with little success), multi-rings-kinda like what Ellegi used to sell. Back in 2003 , had bought two(2) pairs(fronts) from Bruckner Hobbies(Bronx , NY)........good luck, mounting your own foams jus' may be to your advantage on the track.
