Post Photobucket Reboot...........
I remember that when I made the wooden tool tray for my Roadster that it was a challenge, and I nearly gave up.
And so it happened again yesterday when I was on the edge of giving up...................
This time though the raw material was aluminium. I pondered this for a while, whether to go for wood again, of a mix of wood and aluminium, or full aluminium. Clearly aluminium gives a bit more depth than wood which has to be thicker for strength.
So first I tried my wooden cap piece for size.
This method was the basis for the Roadster wooden tray, but in the end I decided to try a single aluminium panel, so I didn't use this piece of wood. The aluminium chosen is 1.2mm thick and quite a challenge to bend on a large piece.

This is how it started. I had to run the Morgan onto that piece of wood to hold the aluminium down so that I could bend it. The remainder of the bending was either in the vice or hammered over wood.

The edges were turned over to provide a flange to attach the sides to, and to give rigidity.

38" is the maximum width.

These measurements were the basis of the cut out for the diff, but the hole was extended to the right as the diff housing is offset.

Initial fit. A protruding bolt in each rear corner makes it a tight fit.

It was at this point I nearly gave up, because it had been really hard to get this far.
Then I removed the protective film............

Next came the side panels. There's really only one way to do this without a fancy cutter........

UPDATE - note that I later replaced these tin snips with some much better items.
More to follow.............
