Nick,
What are the dimensions of the Mk III box? Looks like about 9" x 4" x 2".

Thanks for sending the picture of the inclinometer...

Hi Rob,
It's smaller than that at 5-1/4" x 3" x 1-3/4"

Cheers, Nick

Naw, Rob, your ratios were dead on. I think you used the wrong average rate of growth on the wood sample is all <G>

Ailerons all finally finished after getting the copper roves and little 1/16” rivets.

Some progress with the engine cowl. Originally they would have been spun out of one piece of metal but these days you can’t get a sheet big enough to do that as the Snipe cowl has a 44” diameter and is 17 1/8” deep.

After getting the front part spun I added a 7 inch extension to it. This was done by rolling a joggle for an overlap and then welding. A local young welder did a great job of it.
I then rolled the cable groove in the rear of the cowl using some profile rollers I had made.

Then the truly scary bit, having to cut the bottom section away and roll it around some 5/16” steel tube

Next job is to rivet all the panel locating slots, reinforcement ring, hinges etc

Cheers, Nick
