track retention wall suggestions plz. Rail

[GiantScale]

I bought 65 foam mats from sams club & built a oval track in the living room. 26' x 10' . Im looking for a good retention wall to keep the 1/18th cars & trucks on the track & divide the middle.

Any suggestions on a wall that stays put & is easy to take down & store? vinyl gutter maybe?

Thanks.

1.5" PVC split down the middle. It stays put fairly well and is cheap to buy.

Thanks. But 3/4" is not enough to retain a 1/18th truck or car.

I bought some vinyl down spouts & a heat gun & will try to slip one end into the other & bend some nice radius corners. Not having much luck slipping one into the other yet though.

I kept our RS4's on the track... but a truck would prolly hop right over. how are those foam mats with traction? Do you run rubber ot foams on you on-road cars?

At our local races, my rc18T drives right over 3" tall vinyl gutter. So I need something with a flat tall wall to work. I run pink foams on the mat which I had to clean well before getting the traction I wanted. Never tried rubber yet on the BRP. But the RC18T's rubber tires seems to hook up nice with enough slip not to traction roll it.

After a bit of practice the joints for the square down spout look good & are very tight since one was pulled over the other. I slid them in about 3" after heating.

I have some large radius steel cylinders at work. 8 foot, 4 foot etc. diameter. I will try to heat the down spout , & pull a nice radius corner over them.

A idea always looks good on paper. When I tried to bend it over a radius,when it was hot & soft. Its kinked and looked like crap. And I really want a radius corner! I might just have to make relief cuts all along the corner & bend it around using the mat (radius cut) as a flex guide. All strength would be lost though & Id have to glue material over the relief cuts. Or live with a square track

Its finished now. It took a bit longer than expected, but worth the wait.

Now I dont have to wait til race day to run some laps!

Looks great! How long does it take to set up and tear down?!

[GiantScale]

Thanks man..

It took 20 minutes to tear down & store in the basement. I figure it will take no more than 40 min to set back up.
