Alu rear panel
I'm going to (attempt) to make an Alu rear panel for the car.
Has any one any info on how to go about making this for a book chassis, i.e is there a basic guide on this any were on the web or is it detailed in
any ones build pages.
UNDERSTEER is when you hit the wall with the front of the car.
OVERSTEER is when you hit the wall with the rear of the car.
HORSEPOWER is how fast you hit the wall.
TORQUE is how far you take the wall with you.

AshG might have one. He had a decent walk through in CKC magazine.

Get some lining paper from B&Q, some thick stuff and start with a template.
We riveted the one side and worked around, go slowly and be gentle.

have a look on my photo bucket there are some pictures on there
http://s707.photobucket.com/albums/ww75/ashgardiner/
basically i went and got a roll of thick wall lining paper from the decorating dept at b&q
wrapped it round the back of the car cut it to shape transfered it on to the ali sheet. cut it out clamped it on the back of the car then knocked it
over.
edit.. by the way it took the best part of a day to get it spot on. i used 1.5mm ali but if doing it again i would use 1.2 as it was back breaking
bashing the 1.5mm stuff round such tight curves

I clamped one side onto the rail and gently bent it round, clamping it in places, a few rivets once it was all bent round, trimmed it down, then bent
and annealed the top so that it was a nice fit, then removed it, trimmed and filed the edges, before getting it powder coated.
I think the end result was pretty good, you need to make sure your top rails are round if you want to do this, else it will crease.

My new rear panel is 2mm, and very easy to deal with, the thin 1.2-1.5 alui will tear if not treated well, also the thin stuff will resonante/vibrate
on the car,
hence one reason to change it
I did not make any templates (either time) measure twice, cut once, dont forget to allow sufficent overhang top sides and bottom to loop around the
tubes
Hold the alui in place wih g-cramps with wood to protect the finish,
gently pean the edge over /round the tubes, i used a small rubber mallet, , cut slots/triangles were it goes round bends
DONT cut them to deep
Taking your time, and clamping/re clamping allong the edge will minimize noise, and distortian
when finished, a VERY satisfying job
well the second one was !!
first one 1998, second one 2010

I made a template from a large sheet of paper.
Drew round it on the 1.2mm ali. Cut roughly with the grinder and then tin snips to do a nice cut.
I then had *a lot* of help actually doing the metal bashing. But they wanted to stay anonymous so I won't 'out' them here.
The main thing I remember was that we did each side on 2 different weekends. One was a cold day, the other warm. The difference was amazing. On the
1st (cold) day the ali was really hard to work. On the warmer 2nd day it was much, much easier to work.
HTH,
James

As said above, do it in cardboard first. I never did get the measurements right, and made a big mess of it, so get another piece of ally ready just in
case!
Mine is actually three pieces, but I don't highly recommend that - it was difficult and didn't turn out very well at all. The pics
don't show, but it's a right mess on the top surface around the corners. That was my motivation for making a boot cover.
