Trimming foam to fit wheel weights?

[0lllllll0]

Got some new TSL swampers with foams in them, I would like to add a bunch of weight to the wheels. The last set of wheels and tires I added weight to, the foam seemed to fight me quit a bit. Do you guys trim your foam on the inside to get them to seat better? Seems with all the extra space the weights are taking up you should trim the foam a little.

Any pics showing this would be great!

Thanks

i always just jammed the foam over it.....

Yes, you should trim the foams. I use either a dremel with a sanding drum attachment or an air die grinder with a sanding drum attachment. It will make the foams perform properly and reduce the bounce from over stressed foams.

Does anyone have any pics of this process?

I use the plastic wire brush thingy that came with my dremel to notch the foams.

Usually I just do two runs around the inside of the foam to cut the edges, spaced apart and just deep enough to let the weights fit. Then its just a matter of pinching the foam and tearing it free. Easy peasy.

Do you turn the foam inside out when doing this? Or just cut the inside the way it is?

Pics of this would be awesome

I cut the foams as-is.

I'll see if I can get some pics for you later today.

I layed my wheel with the weight on it on top of the foam marked it with a fine point marker and cut it out with a razor blade. I don't have any pictures of any of it but I don't really know what you would take a picture of anyways. The memory foams were alot harder to cut than the foam ones but if you take your time it works out good. I just wish they would hurry up with the dual stage units for the Claws.

I got pictures! Honestly! I'll get them up tonight, I promise!

I made myself a hot-wire cutter that sliced through foam like a ....hot knife through....butter??
I found myself needing to get some larger diameter foams and also found myself in a state of impatience and wanting another project, so I made the hot-wire cutter as a sort of lathe set-up. Used a power source box, some nichrome wire, various plumbing fittings for the arm, abs plastic board as a base to work from and started cutting. Used an old camping mattress that used memory foam as a sort of self-inflating set-up. Not the best stuff, just what I had lying around.....
Admittedly it won't give the neatest finish, but it did the job for me. Got exactly the O.D I wanted, and by un-doing the wire, passing it through a small hole in the centre of the foam, I got to cut the I.D so I got a foam ring without having to glue any joins
With all this in mind, I'm sure notching the foam to star-cut, add cut-outs around weights what-ever would be easy. Not neat and all professional like, just easy.

Here's the dremel tool I use, its a plastic brush.



And here is a foam that I grooved.



I've done it on memory foam, Rover foam, Nova foam, and F400 foam. Works great.
