what mm ali to use?

[deezee]

I've used a 2mm 5251 H22 for the floor (210MPa Tensile Strength). I then used 1mm 1050 H14 (Half Hard) for the tunnel, behind seats, sides (100MPa Tensile Strength).

If your bolting your seats into the floor (as per the book) You want a beefy grade of metal, plus your going to stand on it. I think the book actually recommends using 2mm aluminium for the floor. 1mm to 1.2mm for other panels. If you want to enter you car into the 750mc race series, it needs a steel floor.

when sheeting your floor etc do you have to cover the transmission tunnel from the underside or can you leave it open. also i take it you use ali rivets?

Some folk cover the floor & tunnel, others have just done the floor.

I used 2mm alloy for the floor ( Left tunnel open ) & have bought 1.2mm for all of the rest ..... Rear panel done, went round the corners a treat
Side panels & interior next

I bought a full sheet of 2mm .... Had enough left from that to make my fuel tank

Yes alloy rivets, the sealed type if possible .

Went beserk with my rivets ..... Every 25mm .... One thing for sure, the floor don't bend when I stand my 14 stone on it !!

I like to leave the tranny tunnel exposed, comes in handy for a quick inspection, refix handbrake switch or speedo cable or adjust handbrake.

Personal choice though.....AndyH

That was more or less my thinking Andy

I also felt it would be a nice collector of every lump of garbage that comes its way

when fitting the rear ali for where the seats are. do u just cut to size and pop rivet as it is, or do you have to do something to the edges (clean them up/round them or sumit)

[twinturbo]

How many sheets do you need and of what size for the floors?

And howmany to do the tunnel?

I got all the interior panels and floor out of two 8x4 sheets easily and have a good piece spare

I used 1.8mm for the floor but a strong grade (cant remember which) it feels plenty strong enough when you stand on it anyway!

Got these prices from my local stock holder.

2m x 1m x 2mm ally tread = £34.20 each + vat
2m x 1m x 2mm ally plain = £29.80 each + vat
2m x 1m x 2mm galv sheet = £26.20 each + vat

Half the price of metals4u...

Think I may pic up a sheet of tread and plain next week
