I'm anticipating my seat cover delivery any minute, hour, day, or week now. I had an idea about the seat pan before I install the new cover, and I would love any feedback from any of you fellow amateur engineers out there. Once I strip the stock saddle I was thinking of drilling a smedium sized hole on each side of the seat pan, then placing an inward facing cap top bolt through the hole. I would cover the bolt head with the new seat, but leave the threads exposed inside the gap below the seat when I put it back on the bike. This would give me a place to mount a little box/trunk, which would be cool if I ever figure out the flip up seat or flip up side panel project that I put on the back burner for my bike. Any thoughts or objections? Something I'm missing? Thanks, Chuck

That's a cool idea, but I think you will gain more storage space with the underseat bag that Krixtoph makes. Or fab something up that sets in place. It sounds like you want to fill that same void but if the box is mounted to the seat pan it won't be able to use the space under the cross brace that spans across the frame to support the seat. Krixtophs bag goes under that brace to give you a surprising amount of storage.
I sketched what I believe you are describing in the thumbnail below. Red being the open space and green being what you are proposing for the box location.
I also attached a photo of the bag I bought from Krixtoph showing how much I have stashed in the bag.
Don't let me talk you out of it. Like I said, it's a cool idea and I'd like to see what you come up with.

Yup, the cross brace kills it from the top. I would have to go with a mini box, like wallet and phone sized. If I fix a hard box to the seat, I could set the hatch to open from the side. It would be a pain to mould something around in there and have to pop a hole in the top to secure to the hanging bolts. I would also have to take it out any time I needed to 1. remove the seat 2. check a wire 3. change a fuse 4. stuff I haven't thought of yet, etc. I guess I just want a lockable storage solution for daily use without having to add any bulk. The leather bag is a pretty simple solution, just not exactly what I'm looking for. I'm going to keep the old wheels turnin', any other brainstorming or idears is welcome.

Just for the record, here is a terrible drawing of what I had imagined. I would like to thank all of the national arts academies in advance for my pending awards...
