It isn't a seven replica, but a rear engined car (R1+50Kw motor).

Here is a bit of cad:


Bought the steel:


48.3x2.9mm round tube
30x60 thickness 3mm rectangular tube
33,7x2,9mm round tube

Freaking heavy ! (and expensive)

Lets bend some tubes :



Yes, that is a Citroën C5 in the back:



Time to use the templates:





Roll over cage :




The pink tape is from this:

Did the same, but with CATIA V5R19 and cut the tape with scissors

Rear all spot welded:



Chassis FULLY(well almost) spot welded:


Cheap gloves only lasted 3 weeks:



Chassis out of the welding room(with some parts not attaced to make it look pretty):



Chassis took me "3" weeks to be built, which means about 75h of work.

Next step (Wednesday), is to steam pressure wash the grease off the tubes, then paint it.

I was thinking about buying regular paint from my hardware store to prevent rust.
Look like this:

Rust prevention for 5years of so. I don't see the point of buying expensive paint chassis.
Idealy I would need to powered coat it, but I don't have a giant oven to bake it. Same goes with real paint, no room to bake it. Cold galvanisation looks bad (from what I have seen), no room for hot galvanisation. Epoxy maybe.

All the tubes aren't in place, but I have to paint it. Because I am doing it at my university, they want a good looking project(and clean), so I must paint it, I told some that is stoopid. But whatever.

If you want more pics, feel free to ask.

Cheers

Looks good, took me alot longer than 3 weeks to have mine fully welded and it was fairly simple ha

I like your fabrication techniques mate, but IMO that chassis looks in serious need of triangulation! Nice design though

Edit: Also out of interest, how'd you stop the pipe from kinking with those benders?

Hell of a workshop you have!!

Why do you bend tubing on the floor?

Have you tubemitre?
