Slider top skin - how do I set these rivets?
Any idea how to set the two rivets circled? The canopy deck gets in the way such that even my thinnest of bucking bars (1/2") and squeezer yokes (used as bucking bars) are too thick. I managed to get the ones right under the spar cap, but neither of the two aft of it. Because they are 426 3-7 rivets, whatever bucking bar I might use needs to have some mass. I've heard/seen people use pulled rivets here, but since the holes are dimpled for 3/32 and since it has to go through the thick longeron, I'm not sure what I could use. It's been so long since I did any signficant riveting that I've forgot all my tricks!
Any thoughts re: what you did to get these couple of rivets would be appreciated.

back rivet plate
I was able to slip my back rivet plate up there to buck them.

Blind rivets
without seeing the other side and not being familiar with the slider setup I'd say install a couple of 3/32 Csk blind pop rivets, unfortunately I don't have a part No for you but they do exist, i'm sure someone else will have another option or part numbers to help you out. Good luck with it.

I used a 1/4" or 3/8" thick steel bar I had around the shop. It was about 8" long x 2" wide so it had some mass. Notch one corner as required to reach the rivet tail.

Thanks for all the suggestions. Spruce doesn't seem to carry those CherryMax "oops" rivets, but the back rivet plate method gives me an idea if I can't find them elsewhere.

I think I riveted them using the thinner edge of a tools pry.

I've had success slipping a crow bar behind places like that. Even bucked one non-structural rivet with a slotted screw driver, pushing on the center portion of it with a bucking bar. Still made a decent shop head.

Canopy frame after deck
I know, the 9 is different than the 7, but, on my 7 I installed the forward canopy frame after riveting the top deck.

Oh yeah, forgot about those - they were a bit of a pain. I got the edge of a backrivet plate in there.
