Re: Make your own bobber style seat.
Nice work, neighbor. It really looks great.
As for springs you don't need to tear up an expensive seat. The springs from any old bike saddle can be made to work. I've used them and I've also used automotive valve springs. Both are cheap and easily found.
I'll be interested in seeing what you come up with. Comfy seats are a must for us bony butted guys and I like to see what others come up with to soften the ride.
Thanks for sharing the build on your seat. Show us the progress if you add springs.
