How I got around an expensive trip to an engineering firm.
When I was building the first Midge, it occurred to me
that there must be a way ( nay, a cheaper way ) of putting
louvres in the engine side panels without resorting to going to
a machine shop.
My hero, John Cowperthwaite, had a method involving the use of
a chisel to cut the slot and, I think, beating the aluminium over
a steel bar. This, I couldn't bring myself even to attempt.
The solution was a hardwood former and dowels - soft enough not
to mark the panel.
I ended up with John including the advertisements in the plans he
sent out.

Many Midge builders will recognize this photograph.
It was suggested in the instructions that people practise first!
I had orders from all over the world and letters of thanks. I was able
to supply formers for a wide range of applications - even doing
some multiple louvres for Lotus Seven copies.
Below is a poor quality photograph of the front panel that
I added later to the Midge.

Another view of side panel.

I was forced to make a new side panel on the new Midge ( for those
of you not paying attention, there will be a test at the end ) and I
now know that it is even possible to use the former with one hand -
just.

The crinkled appearance of the louvres is a fault in the digital photograph caused by -- I don't know what! Resolution perhaps?
I have had to make a new valance for the new Midge. Somehow I 'forgot' to put on a coat of self-etch primer before the undercoat, resulting in paint flaking off. So while I was at it, I put a set of louvres in.
Now, given that I had not bought in fine drills nor fine saw blades and I have not really got around to using a cutting compound, a man on a galloping horse wouldn't notice!
