Ok thanks John

I appreciate all your help

Sure you can self fabricate it...it's not an over elaborate design and is easy enough to do with simple tools. When I fabricated the prototype of this chassis, it was out of acetal plastic, and was done with a jigsaw, drill press, a dremel, and some files.

Those link lengths - is that eye to eye?

Yes, that's eye to eye.

What Baja Shell is that Offroader5?

Ya know...I'm not sure. I bought it as the complete uncut baja from another member on here. It was even painted like you see it when I got it. It came with a piece that goes inside the cab that looks like a driver (kinda like the Wild Willy)...but I took it out. I originally thought it was a Sand Scorcher body, but after seeing it close-up, it isn't. It's real thick, probably about another half again thicker than a standard lexan body.

This was a great read thank you. I plan on starting my wk build soon At forst i was thinking of trying the manta but now im leaning towards the widow thanks for sharing the templates

offroader5 can you tell me what is the weight of it?

With the 8 cell 1500 pack onboard and dressed as you see it with the alum chassis & wheels...it came in at 5 lbs.-12 oz.

I know this thread is a bit old, but I've printed out the widow template and skid... I have plans to make it out of some cutting boards.. I really have no idea what a good thickness is for cutting board material chassis... I am also wondering if the factory axial bent lowers and uppers will work and allow me a decent WB?

I have only ever seen cutting boards that were like 1/2" thick...and to me that would be overkill unless you were scaling the chassis up in size and making it a super Maybe some that have built these out of cutting board can chime in and verify if they found any thinner than 1/2". I have always used 3/16" material...but that was acetal which is more rigid than the HDPE or UHMW plastics that are primarily used for cutting boards.

Not sure on the eye to eye lengths of the stock Axial links, but I can tell you that the links I made for my Widow were only like 98mm long eye to eye to give me a 12.5" WB.

Depending on how you have your link mount clamps on the axle, you could possibly use the Axial links ??

hi from the UK.
i'm new to crawling after recently buying a WK with crawler conversion off a mate and getting hooked.
i downloaded your .pdf's for the lp Widow chassis and Mantra chassis and they're great.
i'm gonna build up both to see which i prefer.

I was playing around and decided to make a chassis from a cutting board I bought from Kmart for like 2 bucks.




I'm not sure of the exact thickness, as I'm at work right now..lol but it seems to be a little less than a half inch. I'm having a friend "supposedly" milling me a chassis from aluminum once i get a design I'm happy with. If the cutting boards are strong and cheap I think its a great idea to test a design out on them, if you like it - create it from aluminum, if not - do another....at 3 bucks you cant go wrong..

i know this is a way dead topic. but I built the black widow LP and assembled it now i have a problem. the rig folds in halve when i hit the gas. i dont know if its the links of the shocks but i need help

What your experiencing is called Torque Twist. There are quite a few different things you can do to reduce the effect. Just do some searches in the "newbie" and "general crawlers" section

[myblack89yj]

i mean that the rear axle catches up with the front axle. from what i understand torque twist is lifting a tire under the torque of the driveshaft

[guywithhat]

your rear axle is swinging under the chassis and yer tires touch? if thats the case.. your link ends need to be re posistioned... if thats not the case.. just ignore my drunk a$$...

[myblack89yj]

thats what i been figuring but my wheel base is a 12.5 and that where i want it. could it be my uppers? how can i tell? maybe my shocks? what shocks should i get?

[guywithhat]

your lowers and uppers should be more or less parrelelelelele.. sp....
if the axle end or the chassis end of the rod ends are mounted too close it will act as a pivot and roll the axle under... hope that makes sence...lol..

[myblack89yj]

well where the links are mounted on the chassis i would say there close to parralel. but on the axle side i have a four link mount that i made and i'm still using the original shock/lower link mount for the lowers.

This is an awesome tread bro' and thank's for posting it up for all of us to see as well.
