Guys

For those already flying or who completed construction, how do you open the top engine cowling?
Or more specifically, what do you have to do to pull out the top retaining pins of the upper cowl?

Regards
Carlos

If you build it to plans, you use the stock top cowl pin locking plate.

The pins have a 90 degree bend at the end, with perhaps 3/8” sticking out. These ends get locked by the plate when it is in the up position. The plate gets 1” or so long #6 screws. To lower the plate so you can remove the pins, unscrew these screws and the plate drops down. Do not remove the screws.

Now, when you get all this done I’ll tell you how to replace the standard pins with 1/8” SS pins and still make the bend along the sides of the cowl.

Thank you Carl

I did imagine that that would be the opening system, but I needed to confirm (just because the plans don’t say it … Whoever wrote the manual do force you to be smart! )

Now, what about your last sentence?

As with most RVs, the plans call for using 3/32” pins in the 1/8” hinge material for the top cowl. This is so the pins can make the turn down the sides of the top cowl. While this works, it leaves some slack in the top cowl so when you fly, the pressure in the cowl pushes it up just enough to irritate you.

What I did on the RV-10 (not my idea, stole it from another builder) was to take 1/8” SS pins perhaps a foot longer than needed. Chuck one end up in a drill press and tapper perhaps 10” or so down to 3/32”. This is a lot harder than it sounds as SS does not like to be worked. I ended up with the drill press on its slowest speed and running a sharp rotary file in my die grinder on the pin. Then dressed up with sandpaper.

Take the pin out of the drill press and cut off the end that was in the chuck, leaving about 10” of taper. The taper ends go along the cowl sides so trim the other ends of the pins to final length.

A touch of oil when inserting the pins goes a long way as well.

I bought socket head 10-24 set screws.  Drilled the end of the set screw and brazed it to the hinge pin.  I have a coarse brass screw for fastening in wood (don't know what it's called) that has a 10-24 thread down the middle.  It is epoxied in the front of the lower cowl so that the set screw goes through a small hole in the cowl nose and then screws into the brass thingy.  I have a threaded part that fits over the set screw and fits in my battery drill so I can turn the hinge pin as I push it in.   A piece of hex key in the drill will insert/remove the hinge pin far enough to clear the threaded insert.

Ah so!!!    That explains the other answers you got. :-[
I used 1/4 turn fasteners. Here's a pic of the mounting strip.

Although I was not referring to the side cowl to cowl hinges, but to the top cowl/fuselage upper hinges,
 
Thanks for the tip, anyway
 
Cheers
