So..... I've gone through three different types/styles of nana seats so far. I've tried the three widest, softest ones I can find available for purchase at my LBC or online. Not a single one of them offer any real level of comfort or quality for long rides, or anything short of scooting around the block, or down the road and back.
While sitting on one of my old skateboard decks the other week it was suggested to me that I should just bolt that on my bike and call it a seat. The more I thought about it, the more I realized it was a great idea! The nose of the deck offered the perfect concave, and geometry that I was already thinking about pounding out of some steel when my wallet could afford it.
I couldn't think of a better way to keep with the rat rod culture than to repurpose what would otherwise be junk into a functional piece of equipment. So after some measurements, I got the cutout done. This is the first stage. I just got back from the fabric store with a yard of quality leather, and a block of reliable, comfortable foam, and a foam shaping tool.
I will post more pics up as I get more done with the project.
