guys, will 18swg half hard alli be any use for a bonnet? too thin? too thick?

got a chance on some cheap.....

I made my bonnet from 18 gauge standard [not half hard] ally , anything thicker will be more difficult to form.
Paul.

Sounds ideal to me

You need the clever stuff as thick ali is ....well thick!

just checked , and its 18 swg 5251-H22 (NS4)

2m x 1.5 m for £10.65....

I seem to recall in the Tony Weale book that the Lotus 7 bonnet was only 20 swg.

"Add Lightness" as The Blessed Colin said.

mine is 20 swg

That's a bargain, snatch their hand off, and send me 4 sheets while you're at it.

Ditto that comment on the price, I'll be interested in 4 sheets if your able to order a large amount.

ATB Dan.
