 Posted: Fri Aug 14, 2009 5:12 pm Post subject: Oil door hidden hinge |
 |
|
Well, I screwed up the FAB and have to re-order the top plate so on to
the oil door...
I have the hidden hinge and am ready to attach to cowl. But I'm
concerned about what fastener to use to go through the honey combed
strips surrounding the oil door cutout.
There seems to be thin honeycomb throughout the cowl but there is a
strip of slightly thicker honeycomb around the edge of the cowl and
surrounding the oil door cutout. After drilling it, It became clear it
is 'hollow'.
So I'm concerned that rivets will not work well. I'm thinking something
like 4-40 flat head screws (with the heads overlayed with glass. Or
perhaps I need to fill the honeycomb with flock then drill. Or cut it
out and fill.
I think the standard door hinges are attached where there isn't any
honeycomb, inside the square of honecomb surrounding the cutout.
Any thoughts?

I removed the core and layed up solid epoxy and glass. Be careful as the outer skin is very thin.

Good instincts, Bill. Replace the honeycomb with flox/resin to make a hard point and it should last forever.

YOU shouldn't need to get into the honeycomb areas of the top cowl to attach a hidden hinge here is a link to some pictures I hope will help you understand the process. http://ivankristensen.phanfare.com/2292606_4268126#imageID=77306227
This hidden hinge and the door latches are from Non Stop Aviation

Thanks for the pics. Yes, I thought that's what I would be doing but
I've already cut too big a hole and am planning a slightly larger door
and door opening. Note to self; cut a small hole then enlarge as more
is learned.
Nice site and pics. Thanks!

Bill,
I cut a bit too much off on the inboard side also. It was pretty easy to just glass what was needed back on... Not a big deal. I left a lip all the way around. The door turned out nice. Be sure to reinforce the latch side cowl lip as there's not a lot of grip area.

You might want to consider putting a couple of metal strips where the cam lock locks on the cowling due to the fact it will vibrate and wear away the composite over time..
Just a thought.

Added some extra glass and a Z-bar stiffener and it seems to work well.
Should have taken the time for the 100% hidden door, but at least it is flush and do not have the do-hickers sticking up.
