Mounted fuel and air pump system and fuel tank. Both are mounted on anti-vibration bushes. You are probably asking why I made 3 fuel tank brackets? Well, the right hand one was easy to measure but the other side wasn't so I made a rough one blind which allowed me to see where it was too long/short and then make one that fits. This worked fine. However, when it came to rounding off the edges and lightening I picked up the test bracket by mistake! Before everything is fitted permanently, I will be tidying up the boot and giving it a light coating of matt black paint.

What's the air pump for? You could have lightened the fuel tank by drilling lots of holes in it

Martin from MJS Fabrications came over and finished off the parts of the roll cage that we couldn't get to originally due to the floor and sills being in the way. Also added a bar between the rear uprights, stiffening wedges in the top wishbones to compensate for the sections I took out to clear the damper pushrods and the driver's seat bracket supports. I can now crack on as the floors, which were holding up the installation of the dash and rear panels, can be installed.

No sloshing as tank is foam filled. Sideways movement is restricted by filler, return and feed pipes. However, once bolted down I will assess whether additional support is required.

Now there is a phrase that I am pretty sure most of will never use!

Gluing in passenger floor.

Roll cage has certainly stiffened up the chassis. One arm of the lift isn't doing anything :-)

Gluing in driver's floor. You may notice that I have only drilled holes in the passenger steet bracket supports. This removed 70gms, or 10% of their weight. They don't form part of the structural integrity of the roll cage, but are acting as seat bracket supports as well as additional support for the floor (they are glued to it) I had the driver's bracket supports welded in before I decided to drill holes. As they are not glued to the floor I will probably leave them as is.

Still quite a large hole to fill :-)

Tyres...bloody tyres, still trying to work out the best combination. I thought I had finally cracked it after years of searching with the Michelin TB5s. However, the size options for 15" rims are restricted and the smallest size for the front is a little high on the aspect ratio (50) than I would like, the 225mm width option is only 5mm smaller in diameter than the 285 rears I planned to use. Pirelli do a P7 Corsa Classic in 305/35 and 235/45 with diameters within 1mm so similar difference but they come in three softness grades. What I can't find out are the Mu values so I can compare 'stickiness'. One of my main tasks at the NEC in January is to discuss this problem with both Pirelli and Michelin to see if I can resolve my (potentially expensive) dilemma as the tyre size dictates wheel width as this has to match the footprint width in order to wring out the maximum grip.

Seats fitted. Driver's is very rigid. Passenger seat (the one I made out of 2 layers of carbon fibre) is a tad floppier :-) The bum part is pretty good but the back section could do with a little support, which I will sort out. However, I won't be siting in it much so no rush :-)

Looking good Shame a Millington Diamond block is so damn expensive ! Would save a lot of weight ....

Are those wooden rear wing support struts a bit high? Are they balsa wood for lightness too?? Seriously... all the best for 2017.

However, at around £4500 - £6500 plus cost of engine rebuild, this can wait until my existing engine needs attention or more power :-)
