maddies drive way 1 ton rover build

[madcrawler girl]

Ya it probably over kill but i guess if it make james sleep at night knowing i wont die its worth the extra 3 pounds. I really want to climb suicide hill and prichett is one of my favorite trails and james wont let me try them if i don't over kill it!!

I like the way you and James think! You need to be around to wipe the drool off his chin when he turns 90

Just remember, more tube does not always equal more strength.

more tube in the right place = more strength


I'm no expert, I'm just trying to keep you safe. Oh, and if you use pink tube, it's 10% stronger


Here's a great article I found on roll cage design:

plus we have one that's a sticky here on RME.

Thanks Steve your awesome to help!!! I was thinking of purple tube to match james would it be strong then?

 

[sixstringsteve]

yeah, purple is 1% stronger than pink, so 11% stronger than black.

While your physics may be true Steve, I do have to point out that you never pushed on the corner of an X, like you did in the picture labeled "cross bracing in the right place", just in the side of the X.

Or that you pushed on the corner of the very bottom of your series of pink squares (the one that looks like a sideways Y)

Or in the corner of the pink square with the sideways "V" labeled "strategic" places...

Just had to throw that out there, that with every design, you will be able to push somewhere and make a bend as you described haha

I tried to find a picture on Pirate that I had seen of a yellow TJ that rolled on its side, and he didnt have enough sideways triangulation just as an example but A: I figured it wasnt necessary and B: I am only on my phone and it was taking too long ha.

i am mostly worried about impact from the top .. i have told her no suicide hill.. but i know she's going to try it. and i know she can climb it.. but its a nasty hill and there isn't much difference in the perfect line and the your upside down line.. so the way she has it designed i think will work great at spreading the load from the roof.. the ^ in the windshided and all the triangulation behind her head should do the side to side just fine ..

the triangulation above her head (not there yet) should also help alot with the side to side impact.

right in the door area isnt too strong but the lower part/slider is 2 1/4 inch .480 wall so i no its not going anywhere haha ( 33 feet for 119 bucks )

the roof will probably be pretty think .. i think mine is 1/8 maybe only 16th i cant remember


i just really don't want her to get hurt

there has been alot of bad crashes lately.. wayland campell and matt from trail gear come to mind.. and scare me i'd hate my self for getting her into this if she got hurt i would blame myself forever

thanks for all the help and input guys i'm not around during the week much to help her so i really appreciate you all being so nice and helpful thats why rme is great!

Steve I don't think they have a roll bender to do that bottom tube

just bend a few degrees every inch. but this build doesn't have time or patience for that fancy stuff im trying to make her race in the trail mod class at w.e. rock dirt riot in april lol

You're exactly right (and you knew this all before). I wasn't trying to say that design B was better than design A in all situations. I was trying to illustrate the point that cage design needs to be based on the loads each part will see, not on a magical shape. We're on the same page.

To the beginner designer (not aimed at anyone in particular), there's no magical shape that is perfect for all loads or all rigs. A lot of people just throw triangles everywhere hoping it'll be safe without anticipating what forces each point will see in a roll-over. I hope my pictures helped illustrate how to think through a potential load and design for it.

Yeah x2 they're some good stuff to think about. Also fwiw if you do need help I'm laid-off right now due to weather so I'm schedule-less and if you do need help I can.

James, Maddie wants her pants back.
(I think those pants rock)

Congrats on the new shoes, those are awesome!

 

[toyota rockhead]

this thing is looking sweet!! good job maddie im impressed! it will look sick once you get the front end narrowed in a little bit

 

[sixstringsteve]

it's crazy how much more motivation you get when you have the big tires sitting next to your rig.

[Max Power]

Looking good.

 

[zukijames]

no more jack stands (shock pressure still needs to be adjusted

 

[sixstringsteve]

Lookin good! Are those hood/fender skins attached, or just kinda sitting there?
