|  Chassis design for the bodiless 2.2 class Just something I threw together for a possible 2.2 bodiless rig. All the measurments meet the rule requirements for '08. I don't really want to attempt a tuber yet so this seems like the next best thing. I plan to cut it out of derlin first then get it cut out of aluminum or carbon fiber once i get all the bugs out. If it's aluminum, I'll run cf body panels and visa versa. The skid will stay derlin. As you can tell, it's somewhat based off of Offroader5's "manta" chassis.  I'm not sure how the angled shock mounts on the front are going to work out, but it looks promising.  my build thread -My wk build so far... Last edited by smcurry83; 02-14-2008 at 08:23 PM. |

| Here's an idea of what it'll look like with body panels. Hopefully the holes in the hood will give enough clearence for the shocks. (all the colors are just to differentiate between parts)  My build thread - My wk build so far... Last edited by smcurry83; 02-15-2008 at 01:17 PM. |

| That is going to look sick when you get it done. I havent even got my WK yet (in mail 20th-22nd) and already went out to get supplies. 1cutting board, 6-32 althread with lock nuts and some tubing to go over. To extend what rod ends do I need? Thanks for all your info. you really inspired me to jump right in. |

| Thanks. I was actually going to start building the prototype out of derlin today, but just I smoked my SECOND dremel in a month this morning!!! I've found that 4-40 allthread with stainless steel tube is plenty strong enough for anything and it looks great. That's what I'm using for my steering and lock-outs. When I get another dremel and start this build I'm definitely going with 4-40 with stainless tubing. |

| I would be curious to see if it fits into the tube/ rod frame rules. I think you will have to run a body on it as it is, it's not tube or rod. But I'm not up to date on the rules for 08. |

| I think it looks pretty cool, i hope its legal for you. Do you have access to a band saw ? they work really well to cut delrin. |

| A jigsaw with a fine metal cutting blade in it is as smooth as silk in acetal.  |

The rules for '08 added a "one year test" bodiless chassis group. I believe the intent was to allow rigs like this to compete legally.  I drew it to meet the specs, so hopefully there's no issues. If they cut the bodiless group next year, I'll just throw a body on it. Actually, by then hopefully I'll have a few more chassis' by then... 2008 rules - http://www.usrcca.com/rules2008.pdf Last edited by smcurry83; 02-17-2008 at 07:48 AM. | |

| Any one have any ideas of how to go about finding a fabricator to build this chassis for me? Even someone on-line. I've looked up a few shops in my area and it seems that they only do large scale, high quantity work. Anyone got anything? |

Sweet, thanks a lot. I just don't have the time or resources to build a chassis out of aluminum. I'm trying to break down the wife to let me get a mini mill. I found a sweet mill/lathe combo I want. | |

| Update: I decided not to angle the front shock mounts. Instead I will use allthread and stainless tube straight across. This way I can adjust the angle of the shocks by placing wider spacers between the chassis and the shocks. The chassis drawings have been handed over and are getting water jetted. Can't wait to see the finished product. In the mean time I'm going to work on the body panels and braces. I'm really hoping to get some nice cf for the panels. I think I have a hookup on resin and cf off a roll, so I should be able to make some nice custom panels. |

| Well, it's been a while, but I just got my aluminum chassis plates in the mail today. They look awesome!!! I'll try to post pics soon. I've been pouring $$$ into other hobbies for the past couple weeks (motorcycle, jeep, fishtank) so I'm short a lot of supplies to start this build. I was planning to have all of the all-thread, stainless tubing, new shocks, wheels & tires, misc nuts & bolts and a 3ch rx / tx by now. Hopefully I can at least get ahold of the allthread and the stainless tubing this week. Stay tuned... Last edited by smcurry83; 03-25-2008 at 08:36 AM. |

| I need opinions... Should I just leave them finished like they are, or polish them? I would like to polish them? I think it would look pretty sweet, but I think I would pissed everytime I scratched it and had to repolish. |

| For my aluminum chassis, I like the brushed look, and like you said...it's going to get all scratched up anyways. I use a rubber sanding block with 400 grit in it to dry sand my pieces first, then use 600 on the block to wet sand...and they come out shiny, but not so much they look polished. On the other hand if you want the polished look, and If you know anyone with a tumbler or shaker, you could have them throw it in there with some abrasive stones and have it cleaned up to a mirror shine. |
