I've had a plan to build me a custom king and queen seat for my motorbike for awhile now, but couldn't seem to find the time to do it. It's a pain in the ass. I got tired of having a seat bungee corded to my frame like some clown. That said, I consulted my adviser of chemical reaction, Danny and my adviser in terms of technical proficiency, Josh and got to stepping. I planned on mounting the seat to my existing seat hinge up front, to allow me to switch back to my solo seat if I ever got the urge. So I cut some 16 gauge steel for the front section where it mounts to the hinge. Wasn't sure how strong the fiberglas was going to be. Drilled some holes in the pan to allow it to rest on the seat spring spud jams. Also, at Josh's request, drilled some 3/8 holes randomly in the pan so the resin could flow through and bond to the other side. Covered everything up with masking tape, then saran wrap so the fiberglass would pop off once hard. Fiberglass is nasty and stinks. But quite enjoyable. I built it up a layer at a time until I had it about 1/4" thick. Then sanded and trimmed it down. Turned out pretty good, I think and it's pretty damn hard. I realized I need to trim the front section down a bit so it follows the line of the rails. I'm going on vacation for a couple weeks, so the plan is to drop it off at the upholsterer and hopefully it'll be done when I get back. Party scene. Out.
