KR> cowl hinge mounting

[Tony King]

I have a Fisher FP202 Koala with hinge pins holding the upper cowl on (the
lower cowl is held on with screws).  They work great - takes about 10
seconds to get the cowl off for an engine check, and about the same to put
it back on.  One pin down each side and two much shorter ones across the
front.  They're about 20" long but they just slide in - no need for tools
or equipment.  Each pin has a right angle bend at the end to make a kind of
handle, which makes it much easier to slide the pins in.  There's also a
small stud (basically a screw head sticking out about 1/4") in teh lower
cowl that the right angle bits clip into to stop the pins from sliding in
flight.  It can be nasty if the pins slide out into the prop - and the cowl
coming off is not the worst bit.

Cheers,

Tony

KR> cowl hinge mounting

[Richard Kaczmarek]

My KR and several other aircraft I own have the wire hinges for the cowl
and I have never had an issue.  Take a look at how Van's does theirs. It
makes for a nice clean look and a better looking fit on the cowl.

KR> cowl hinge mounting

[Patrick Driscoll]

About 30 years ago, I flew  Fly Baby from Minnesota to Florida. The cowl 
had a hinge and wire set-up and the wire was not secured at either end. 
Twice after landing, I had someone ask me what type of tach I was using. The 
wire would work out about 5 or 6" after about three hours flying and it 
looked like the prop would contact it each time it passed. (it wouldn't go 
out far enough to actually touch the prop). People sure thought it was a 
tach.

I seem to recall an article in Sport Aviation many years ago about a 
Midget Mustang builder who attached the cheek cowls with piano hinges. 
When installing the wires, he would lube them with something which I 
have forgotten and spin them slowly with a drill while running them in, 
reporting no problem with that method. This was before powered 
screwdrivers. MM cheek cowls are pretty long but the curve is not too 
sharp, so, not sure if the drill technique would work here.

And also, use the rolled hinges, not the extruded, for this application.

Something I've learned since then is to use the narrowest hinges available
to save weight.

I found several photos detailing the hinge joint installation, and have 
put them near the bottom of  http://www.n56ml.com/cowling.html. Looking 
at the time stamps on the pictures, this process took me four hours from 
start to finish to fasten the hinges to the top of the cowling (judging 
from the photo timestamps).  It went somewhat faster on the bottom 
because the location was predetermined.  Something I've learned since 
then is to use the narrowest hinges available to save weight.  They'll 
be fine...
