I decided to start a category in this thread rather than put it into my build thread, thought maybe it might get more traffic here... who knows?
I'm trying to get things finished up on my long-running (too long) CL378 build so I can tear down, paint the frame, and then get it finished up once and for all. The question I have is if any of you might have suggestions about seat mounting or ideas about some kind of unique or special fasteners that might work for me.
As shown below I've got an electronics tray that's going to ride under the seat.
Because of this, I can't come up through the bottom w/ bolts to secure the seat pan, I need to find some way to fasten it to the frame so I can get it off relatively easy when necessary but, of course, it needs to be securely attached otherwise. I had originally planned for an aluminum frame bolted to the bike frame that the fiberglass seat base would then bolt to. But doing that forces some way to remove the upholstery to get to the bolts. The guy who's going to do the upholstery wants me to come up w/ my fastening so that he can then work around it when doing his work. Though I didn't originally want the common snap fastenings along the sides and up over the hump I had pretty much conceded to that plan but he says that depending on my solution me may be able to come up w/ something that will eliminate using snaps.
I have some stiffening bar mounted on the bottom for stiffness and proper spacing/positioning, that's the button heads you can see in the pix below. Also there will probably only need to be one fastening on eash side more toward the rear as the front will be held in place by a metal tab.
Anyway, one idea I've come up with is to put holes through the side of the seat base into a tapped hole in the side of the frame rail. I'd have to use spacers between the fiberglass and the frame to prevent squeezing and cracking the 'glass and deforming the shape. Pix below shows the relationship between the 'glass and the frame rail.
If I went this way I would probably use something like an elevator bolt like show below to take advantage of the flat profile.
So, does this seem like a workable solution? Am I too close to it and over thinking it, making it too difficult? Are there some kind of fancy fasteners or something out that that would help me out?
