No pics, but if you can visualize a bit, here is what I did:
where the seat lip goes over the lower front tube, and behind your back
the upper tube, I scuff sanded, and cleaned the top and bottom of the
pan with MEK and layed up about 6 layers of additional glass cloth. I used
polyester Resin, as I think the seats are polysester resin based. In any case
it sticks well.
With the seat pan in the plane I marked with pencil where the frame tubes
were located. I then removed the pan, and cutout 3" wide strips of .025
aluminum (6061) the full width of the flat area of the pan (under your thighs,
and behind your shoulders). I did an inside and outside piece for the four
flat sections of the pan (8 pieces of aluminum). These were located right
behind the pencil marks. I painted them with polyester resin, and thru
riveted them in place sandwiching the seat pan between them. The rivets
I used are 5/32 Avex every 40mm around the periphery of the aluminum.
(I'm also a Zenith builder so I have a ton of these rivets on hand)
Next through all this mess I figured out the best places for my cable ties to
go and drilled holes all the way through. So the ties are going through the
upper aluminum, seat pan, and lower aluminum and around the frame tube.
So imagine under your thighs there is a strip of aluminum left to right directly
behind the frame tube, both above and below the seat pan, through which there are six
3/8 cable ties. Same behind your back, and copied on the CP
side.
This might be an enormous amount of overkill, but I do NOT want my seat
to break loose.
I will also say that I even notice that the seat feels firmer .... Something I
previously thought was the foam in the seats.
My seat install originally was exactly per Skystar's version of the instructions
with no deviation, which like a lot of things I now think (after ten years
flying it) was inadequate. Like I said I'm about 170, and have only ever had
1-2 passengers over 200 so the seat has never had a heavy load. It just was
not strong enough by design over the frame rails.
