more pics before i start long bar is so i can line up both chassis



cut chassis

spigots turned down so can tap inside tubes for tight fit before welding 7 of these reqd


spigots in place

chassis tubes to extend chassis 18"


turned drilled and taped inserts for rear chassis tubes to take rear bumper


rear inserts in place

this saves alot of work with hack saw


all tacked together after a lot of checking and double checking


pic with rear axle in place to check its all square and true, the tubes next to it are for the next bit of the chassis to stop flex and to give a bit of side impact protection which you will see on the next lot of pics
thats it for now.

is there not a way of making a pivvoting chassis so the front and rear can flex a bit all be it not independatly left and right, just back and front slight movement from the center part of the chassis?
it will give it that slight movement these need to not be lethal imo.
even if its just some rubber that compresses a bit over bumps to allow movement.
if i wind my r1 suspension up rock hard it skips about and handles crap, if its got movement its perfect
