|  Chassis idea
Im think im going to biuld a rock crawler for fun, i did some research but my chassis idea is a toatly new way. Could i use a wooden chassis? I wood make 2 pieces of wood come together with a plate under it to support a tranny like an e-maxx tranny with revo drive shafts. like this but wood and the frame a little longer, like a v with 2 lines (-v-) http://www.rccrawler.com/forum/showthread.php?t=125445 |

Ummm...... There is usually 2 reasons something hasn't been made before... 1. Its so new and radically awesome that no one was ever smart enough to thinking it up 2. Its gonna fail, everyone knows its gonna fail. So no one even thinks about trying it. |

You'll never know if it works until you try it. I say go for it.  Atleast it will be different.

joe, you forgot number 3, everyone thinks it will fail, so nobody tries it.

Go with number 1. Composite wood construction, multiple layers of very thin 1/32" or 1/16" laminated and molded in the shape you need for a chassis of a unique design. Mike | |

The problems i see with a wooden chassis is,if it gets wet it will swell and be bigger than comp rules allow,or get wood rot, or infact just float away alltogether!. And if you run into a beaver out in the woods it wil eat it,or even a woodpecker could attack it! But give it ago,just spray it with insect repellant,that might help. |

I used wood when building my first chassis to kinda map everything out and mock it up, it's a pleasure to work with. Once I had it laid out ok I mounted everything up to check it out. It was originally just going to be a mock up but I got impatient and began running it. It held up remarkably well. As long as you have some bracing side to side I think it could last just fine, I used my braces in between my shocks to help provide maximum support. Especially if you use some better wood than what I used. Mine held up great crawling, but finally broke when a friend picked it up by grabbing both top rails and squeezing. I don't think it would hold up to some of the stuff I've put my car through since - I didn't take the woody off of any big drops or anything. My friends gave me all kinds of grief about it, but I think they were surprised how well it held up. Termites, beavers, woodpeckers, carpenter ants, floating away in the rain, etc. The bottom right chassis is the one that I ran:  |

My initial thought when I read the first post , and noticed it was his first post I pictured a chassis made out of a 2x4 with nails pounded in it. Why would anybody want to use wood? was my next thought. Then I remembered a lot of guys don't have metal working tools, I don't know if this is the case or not. So... can you make a nice chassis with wood needing only common hobby tools? We make nice planes and boats with plywood so I think the answer is yes. The fact that the material needed is flat will make it easy to come up with number of different composites using plywood epoxy and fiberglass. The only obstacle is the beavers and wood peckers which I have no answers for. Mike |

well here is a quick chassis draw up, i will be using i think a e-maxx tranny, savage shocks or t-maxx, and x-factor axles or axials, and revo drive shafts. I will cut my chassis out of wood tomm and sand it in school. Is this a good design?? How long should the chassis be?? There is a pic without a side brace do i need on or dont matter? http://i454.photobucket.com/albums/q...8mt/mo2001.jpg http://i454.photobucket.com/albums/q...8mt/mo2003.jpg http://i454.photobucket.com/albums/q...8mt/mo2004.jpg |

Hey, Build you rig...... axles, shocks, tranny, links, lay it all out like you want it, then build a chassis to fit. Last edited by Mike Poulson; 11-07-2008 at 03:29 PM. |

I'd say you need more substantial TVP's than what you have drawn up.

I have a stack of denim here that I was planning on making a Micarta chassis from....maybe it's time I get started on that  Quote:
The lamination/resin will give it much more strength. | ||

You can laminate wood into all kinds of shape and size!! Go for it! Let them laugh, but it'll be lighter than a delrin or aluminum tvp plate. Just won't be as strong, but hey...innovation!!

Woods cool i use it for almost all my prototypes due to the fact that its alot cheaper to work with. I made a baja chassis for my stampede out of wood and a 4x4 stampede chassis out of wood even my first crawler chassis. (this was before i ever had a company lol) Woods cool but durability in normal conditions isnt what a metals is. still cool though so go ahead and make it |

I think wood alone is alittle troblesome for durability. What you need is some light weight fiberglass for covering and reinforcing. Go to the airplane area in your local hobbyshop and look for "sig cloth" and an apropriate epoxy to go with it. One or two layers of this stuff should provide the strength and stiffness needed.

Chassis will be plexi-glass cut with jig-saw, here is the 3-d setup. Will it work?  |
