. The picture of your left wing stub I see somthing just above the
> main spar that looks like it must be some kind of opening for cabin
cooling.
Yup it's a home grown NACA duct for cabin ventilation, I think i've made it
too big though, time will tell.
I just marked out the shape on the 3mm ply sidewall, and cut out the rear
section with a jigsaw.
Next I cut the front surface where it bends in with a sharp knife to just
cut the top ply and bent the cut out piece in, the rest is made from 2 bid
which was just laid up flat on my workbench then cut to size and shape and
glued into position.
. Also did you make your own engine mount? I am installing an 0200
Did you have some kind of jig to make you mount? Any tips? thanks Jim
Yup made the engine mount myself too from some drawings kindly supplied by
Jeff Scott.
It was a lot easier than I thought it would be!! I made a mock firewall with
the holes drilled to the engine mount pattern, and laid it down on the
bench.
Then I made another template for the bolt pattern to suit the O200 from some
1/4" scrap ply.
Next I cut four pieces of 2"x2" and nailed them in position to space in
between the two, so the engine template sat 12" above the mock firewall in a
position to put the thrust line in line with the top fuselage longeron.
Then it was just a matter of building the engine mount between these two
flat parallel surfaces.
I used a mig welder to tack everything together so it didn't get the ply
sheets too hot and burn them, and then I removed the mount from the jig and
gas welded it all together.
I've added a couple of pics to my yahoo photos page so you can copy the
plans out if you wish, or if you send me your address offline I'll send them
to you.
