Scott,
Thanks for the input that helps a lot . This seat is going to be a solo saddle. I made the seat pan out of fiberglass so that I could have something more form fitted to the frame. I plan to just do a seat with top and sides. The bottom of the pan is just going to have a heavy fabric and some rubber grommets at contact points on the frame.
You bring up another thought... I had not thought about wet forming the leather to the seat. I plan on using 6oz on the top and then 4-5oz on the sides. As this being my first seat I was following one of the tutuorials by Paul Cox (for those interested: http://www.bikernet.com/garage/coxseat.asp ) where once the seat is dyed and stitched he then used an adhesive to attach the leather the foam and the riveted it down. I was thinking of getting a good fit and then using the rivets and adhesive to "cinch" down the leather. The seat is fairly basic in curves and lines, no dramatic or large pitches in the foam.
Would I be wrong in assuming that by soaking the leather then it becomes more workable when fitting it over the leather and then as it dries it will shrink some pulling it tighter to the seat?
Thanks,
Randy
