Hi David

I now appreciate the magnitude of your repro problem....... why the H&^%* would they design it like that in the first place...... I am sure it gives the whole side piece more ridgidity but short of a die stamping operation it's a night mare to replicate...... the top part could be done in three pieces and tig butt welded but what a night mare.....doomed to warp with heat.....

How un-original would it be to do a flat top bend like other boxes of the period.... sure glad my 2B1 is stupid simple...... and I might cheat by using one gauge lighter all around..... after all I don't intend to over load it.

Good luck with the rivets and don't forget to show us how you made out....

It should be possible to make the sides in one piece without much trouble . I can email better pics if you need them. Make a up a die former out of a length of pipe and use a press.

QUITE OFTEN i CAME ACROSS A ROAD BLOCK, when building the 1a1 BODY... i WAS TOLD " NO WAY TO DO THAT " BUT YES, IT COULD BE DONE .... MOST OF THEM WERE TOO LAZY OR NOT INTERESTED IN FOLDING UP STUFF. i ENDED UP doing some myself and the complex stuff .. I found a great place at Morwell who were very good .

Hi Mike

Thats the one David ..THANKS

My first C8 was Z4544183.. close to that one pictured

David in Texas: To make the sides , you will have to make up a small press using scrap metal and a auto bottle jack ... bolt this to your bench .

First , fold up the sides and for the top edge , fold in the basic L shape as per the drawing , but without the curved section .

You can make a simple die from a 12" length of hardwood , or metal, your choice ... It only needs to be 12 " long as you go along and press down onto it slowly astep at a time along the whole lehgth of the side panel.

Slide the die into the L section you formed in a folder, and go along and press a short length of pipe down onto the die .... the pipe needs the correct diameter for the curve .

After its done, hit over the short edge per the drawing , again you can use the same die , if its made to the correct dimensions .

As its only 1.2mm guage your using , its pretty easy to do this job
