Being a maintenance man for a few years, I worked with this stuff a lot. If left as is, it will peel and pill up when friction is exerted on the surface. A good coating of something else (like rhyno liner) would keep that from happening.

yep, but it's a good thing to lay down to get the right shape. and would hold the weight of a crawler pretty well. but you would need something over it to prevent it from coming apart (every tried crawling on bare styrafoam.....I hope you've got a good vacuum!!)

Hey
This is a buddy of Casey's. He is at the MN nitro series in Duluth MN. Just talked to him today. He is pumped up about this and will not be there for this one. But he said he will make the one on the 15th. I will be meeting him there to hope get into this also as i'm a truggy racer. And hope to add this to my belt also. Later Scott

I am still coming up with ideas for this. It will not all be artificial, there will be some natural rock and some landscape objects. I would like it to be long enough to be a course, not just one crawl. Ideally, I would like to have a few GTG and/or comps at my house over the winter.

Any more ideas? I will be talking with Jerry and Jerry Jr. at Jerry's RC pretty heavily about this over the next couple of weeks. Then it is on to designing and building.

Thanks,
Casey

RC-ROCK-ON · 10-16-2006, 09:31 PM

Well Casey,
Package will be here Wed. UPS. So plan on having one more 2.2 running in the indoor this winter. I will give you a call sometime this weekend to see how things are going???

freetimecrawler · 10-17-2006, 05:05 AM

Casey, if you want any help on building this? Just put a shout out in the MN thread and I'm sure theres plenty of guys willing to help. We've got a great group of guys here.
I'm going to be in Chicago this coming weekend with Probeater (Oct 20-22nd) for the I-Hobby show, crawling on RCP's artificial track. Theres some pic's of that in the general crawlers section under " anyone insterested in crawling at I-hobby"
I will get some pic's of that course also for reference.

Scott, Welcome to RCC, post some pic's of that new 2.2 in the "any crawlers in Mn thread in the GTG section when u get it. Most of the MNRCRC club hangs out/posts in there.

Also, have any of you MN/Wi guys checked out the new MNRCRC forum at EtypeR's Turtlecrawler.com yet? I know the IL and Ia guys are posting up in there. There's a post about this with a link in the MN thread.
We have a 2007 MNRCRC rules discussion going on in there. We'd like to get as much input as possible. We will also be having a MNRCRC club meeting sometime in early Nov. The info for that will be posted in the MN thread in the gtg section.

Also check out the Howl Krawl gtg on Sun Oct 29th in the GTG section. We've got some great trail running and also some crawling going to take place

madscrambler · 10-17-2006, 02:52 PM

I would use expanded lathe used for laying tile then form it how ever you want to and mix up some thin set nice and thick and smear it all over the lathe you will have to put some braces underneath it so it can handle the wieght but it should work great . Thats my plan for my garage anlong with a nice pile of real rocks .

Im plannin on doing that exact same thing.....

rockmike · 10-19-2006, 09:53 AM

well ive got an idea on this topic go down to the local foam shop and buy some 4'x8' foam boards .Ive senn them in a variaty of thicknesses.You could cut them down to 4'x4' for easier moving.But anyway glue some together to get desired hight,you could stair step them or whatever.When youve got youre basic design then take a small chain saw[might whant to do this outside]and start carvin,cut in gullies and crevises dips bumps whatever youemagination would permit,leave some spots uncut for sharp steep edges.Then coat it with the bed liner or automotive under coating[cheaper]and while doing it make 2-3-4 of them make them modular so you put diff ones together,it would be easy to move them around,you could change the coarse easy enough to make it more difficult when needed,also easy to load up and take to a budties place or aparking lot.Just my 2 cents whatcha think.later mike

Etype R · 10-19-2006, 10:10 AM

Some time this winter I want to try laying some thick fiberglass, or maybe just some thick cloth over some foam and covering it with resin. Once its cured, cover it with a bed liner.

Rockpiledriver · 10-19-2006, 11:26 AM

You can spray the bedliner material directly over the foam. It goes on at about 120 degrees, so if you keep a distance of about 3ft when spraying, you shouldn't have any melting problems.

I used standard white styrofoam 4ft x 8ft sheeting for the RCP Crawlers display.

rcracer · 10-19-2006, 07:21 PM

Just wanted to add what I did, used great stuff on a 4x4 board, used plastic containers for filler and then more great stuff over top. finally coat it with herculiner and done. it took 1 gallon and 1 pint to coat so ending cost was about $100.

hotwheels000 · 10-19-2006, 07:38 PM

I was thinking about this ...What if you used a hoppergun for spraying texture, loaded it with grout or cement, to get the consistancy you wanted use elmers glue instead of water. It would be a great binding agent and the surface would be more of the texture of the rocks. Sprayed on thin enough to be light but thick enough to hold up to the abuse

run2jeepn · 10-19-2006, 11:20 PM

All you need to do is get some cheap roll on Bed liner. Most the cheaper Bed liners have alot of sand mixed in it. So you got the bed liner holding the foam down. Then you have the texture of the sand for that insane grip.

It would cost like 100 bucks to do that.

or buy 3 cans of the 1000x expansion cans. it works well at filling in key holes in peoples front doors, but i wouldnt know from experience

wrightcs77 · 10-20-2006, 02:10 PM

Thanks for all of the input and ideas. I want to be able to do the whole course for a few hundred dollars, so spending $100 on a 4x8 sheet probably wouldn't work too great.

I am thinking maybe taking some chicken wire and shape it the way I want, put a plastic tarp over it and then put some thin cement (quikrete) over it. Do you think the quickrete will adhere to plastic tarps? Just a thought. I like the idea of the 4x8 sheets of foam, make them somewhat modular, so you can re-use them from different sides and in different orders.

Thanks,
Casey

It sounds like a fun project to do I wish I had the space to do somthing like that here in Alaska. Here are a few links to fake and imitation rocks that might help you.

Ok, all this talk but has anybody built anything yet, let's see some indoor coarses.

rockmike · 10-31-2006, 10:23 AM

so has anybody built anything yet lets see some crawlin coarses,ive started a test piece,with some spray foam,cardboard boxes,ill spray it down with ruberized under coating,and weel see if its worth 2 squirts or not.trying to keep it on the cheap,cause im that way.

jetboat · 10-31-2006, 01:00 PM

Ive been working on mine since the weekend, almost have it done, check this post, Ive got some pics on it and discussion on how Im building it Man-made rock obstacles any info ?
