Default Wing Tip lens installation

How do we install the nut plate rivets? Will using a bucking bar will place fiberglass in danger of cracking? Is there an easier way to install lenses?

Default Wing lens

Very nice but do you think 1 screw will hold it? I saw pictures on the forum where they used 18 nut plates per wing.

I used three nut plates per lens... just use "Soft" rivets or small C/S pops as you're just holding a nut plate in place for a lens.

I used the Click Bond system for my wingtip nut plates. My light lens nut plates are standard Spruce plate nuts, but I used the Click Bond adhesive to attach them to the wingtip. Actually any good epoxy will do...JB Weld, etc. Just be sure to scuff the backside of the nut plate before bonding.

Smear of 5min epoxy & flox under the nutplate and nutplate pop rivets. Pull the rivets just enough to snug the nutplate. Let it harden then finish pulling the stems,

I bought a bag of PASK302 rivets (3/32" c'sunk flathead blind) from Hanson Rivet and Supply for jobs like this. Very handy.

Default Backing strip and bucked rivets...

I used a strip of .20 with a bit of epoxy as a backing strip and bucked rivets for two screws.

Default Two screws

per lens, no metal backing strip. After more than 4 years and 1100 hours, no problems.

Default wing tip lens installation

On last three airplanes I have used just two nutplates, one top and one bottom like Jamies. Just make sure you get a good fit between the mounting flange and lens. No extra reinforcing of fiberglass necessary for riviting the nutplates. I have noticed most of the ones that have all the screws in them are the ones that did not lay flush to begin with. If I were to do another one, I would round off the corners of the lens and the flange.... Just a little more of that detail work.
