F4i wnb stunter -build

[Petomaani]

Spent few hours at the garage yesterday, just fabricating front mount for passenger's seat:








Some random pic under subframe: battery tray still missing (it's quite ready, needs to weld it on) and passenger's seat mount needs to find it's place:




Crash cage's bottom bar - it's too wide from the bottom, I think I'll bend a new one:








Sorry for bad picture quality, next time I'll take my DSLR with me...

[Petomaani]

I fixed the crashcage's bottom bar by opening lowest bends littlebit and cut it half from the bottom of the engine:




Here's a pic of the bottom joint -> I didn't want to make any flanges... There's thinner tube inside this joint: other end has been welded into crash cage's right side's tube and other end has been locked with these two bolts to the cage's left side. We'll see if this joint will be strong enough:




Rear view:




Motormount tubes has these thinner sections which goes inside the frame's motormount pits:




Here's two pics of the nearly finnished subframe. It still needs undertray, plates for all electric crap and mounts for the rear pegs:

Wow, you put a hell of a lot of work into that subframe! Good job, I cant wait to see how this build turns out.

Looks good! Make sure to bring that beast to SMASH 2012 in Estonia.

Thanks for the invite I've heard those are THE killer parties

I made rear brackets for the cage yesterday, still needs horizontal tubes and some welding - looking good!

i cant believe is still see NONE of the f4i cages made like i had them made: with a crossbar between the headers, with a lip that goes into the place where the motormount spacer normally is. the cage gets fuckin rigid like that, 10 times stronger then with a big ass loop and way better looking. my cage lasted 4 years!!

This made me rethink my cage desing - I wasn't aware of this kind of solution you've used with your cage and I think I'll follow your design!

da Liks, i`m rebuilding my f4i right now and i wanted to see your design.

Have pics?

Petomaani, nice build, i`ll throw mine too in another topic
