do you have any spare gearboxes for the renault?

volvo is probably a better bet, indestructible.

No spare boxes... yet!

Some slow progress, will clean it up this weekend.

~ 9kg removed in underseal, redundant brackets and general dirt!

Ace work chap! Where have you fixed to the chassis at the rear with your roll over jig?

Cheers! I fixed it on the rear panel, near the lights there's two M8 holes already.

I'd only want to do this if it was a shell mind, the alternative was to weld something temp into the roll cage. Kiz opened up the rear chassis legs, which is a good shout, but it's part of the rust that I need to repair.

Shell is light enough you can pick it up either end, I'm no Arnold, so it's not that heavy  ;D

Many hours spent to get the remaining sealant/rust/paint off the floor, can start welding next week I think.

Pushed outside for a good blow down:

Then back in the garage to have the remaining paint removed:

Some of the nastier pieces:

Left me with this:

Be nice to start adding bits back after 3 weeks of removing them!

Cheers

Completed a good portion of the stitch welding now, utter pain with the cavity wax, despite a hot air gun and blow torch for hours, it still comes flowing when you start to weld...!

Penetration shots:

Ground down some of the less beautiful welds, and dressed all others so they're smooth.

Then started on the interior, not much to do here, only a few seams (previously did all the others when cage was fitted):

Got to flip it back over to do the other side, then make some repair panels for the crusty chassis leg, and sills. I've also got a load of laser cut plates coming to weld in over redundant holes, saves me cutting individual shapes out.

My plan is to etch prime the underside, I'm not done with the fabrication, but I can weld through the etch, and should offer some rust protection whilst it's bare metal.

All for now!

Cheers

Last week or so has been spent cutting out rust, welding in new steel, and plugging holes. Not very exciting, I'll be glad when it's finished.

Started with some laser cut bits:

Untitled by Peter Strange, on Flickr

These were to cover various different holes, some factory, others done by myself over the years of bolting many different things to the floor!

Welded both inside and out so there's no path for water to enter, etch primed before welding, which isn't as clean as welding to fresh steel, but hopefully provides some corrosion protection:

After that a good wire brush down, panel wipe, and spray with etch prime:

The panel on the right of the picture above, is the OSR floorpan. I twatted a barrier at Oulton Park a good few years back, the 'bodyshop' who repaired it at the time, decided the bent floor was best left and undersealed over... chassis leg had subsequently rusted as had the floorpan. The rear towing eye mounts here, so I've replaced both the floor and chassis leg with Zintec, and will buy a bolt on towing eye.

Additional work, but I want the chassis to be as rust free and solid as possible. Fuel Pump wiring hole plated over too as the pumps will be mounted on the tank.

And finally the spare wheel well, several rust scabs that i'll be cutting out and welding fresh steel in, I need to decide if I use a steel panel or a carbon fibre one.

Fairly boring update, next one might have shiney bits in it... maybe.

Cheers

No more heating?
And does the wheel well add structural strength? If so, how are you going to handle that with a carbon fibre plate?

Correct- Heated screen going in  ;)

Wheel well is an interesting one, something I'm still working out. The area is clearly behind the rear axle pickup points, and the body is well tied together around the rear axle mounts (roll cage helps too).

Having been crashed into in a Mk3 Polo, the wheel well did nothing (crushed the spare wheel), and previously with a 2mm steel plate when I hit the barrier at Oulton, I still bent the floor.

Guess I'm saying I'm not convinced a 1mm steel plate offers any benefits over carbon fibre, it does mean I can put jerry cans etc ontop of it though.

If you want to see examples of cars without anything behind the rear axle, many Auto Test competitors literally lop the back of the car off (roof and all), whilst their cornering speeds aren't as high as a circuit car, they clearly maintain enough body rigidity to have consistent handling characteristics:



Slightly extreme example granted!

So, been a while since I updated this, boot floor is now almost done, just needs a plate putting in place, but the hole is useful for access currently.

Chopped the rust out and welded fresh steel in (the laser cut plates):

Then once I'd done that half a dozen times, it was looking a little better:

The towing eye to chassis leg was all replaced, rather than re-make the steel U-clamp I opted for a JDM/racecar strap, so made a mount:

Then a lick of etch prime, and welded the remainder of the rear panel back on:

After that I needed to set the rotisserie bob on level:

Decided a while back I wanted to put some pukka sill stands in, makes working on the underside much easier. Something like this:



So, some CDS ordered for the female recievers mounted in the sills, I can also make the stands out of this, will order some bar at some point to make the pins from.

Decided to use the roll cage feet. Not FIA/MSA approved I know, but this is by far the strongest/neatest solution. It's a pain to drill straight, but taking time (about 3 hours) and lots of measurements gave a good result:

Outside (small hole is from the side skirt):

Poking through:

I've left them a little long, as I'm going to make a side skirt incorporating the arches/floor. I'll take 0.5' as a result!

Have to make some 3mm plates, plate the tube, then weld it all up. Oh and do it another 3 times...

Cheers

I wanted to ask this for a while, but always forgot to type it out. But did you put your car on the scales before and after the gearbox conversion for comparison in weight increase and weight distribution?

Put on 25kg with the box, most will be NSF
