After finishing the seat, I decided to build a custom sissy bar back rest to match. I don't usually put back rests on my bikes because its hard to find one that matches the seat colour and the shapes and sizes sometimes seem so bulky and out of proportion. I decided to start with an mdf base that I cut out on the CNC at work. I pocketed the back side to accept a CNC cut backer piece that I made out of some high density plastic. I have a whole skid of the stuff and this is the first time I have actually used it!! The pictures of the sissy bar pad I made here are of the second try. On the first attempt, I painted the squares first and then tried to wrap the vinyl around the curve. It just didn't work out because the vinyl bunched up around the bend and made the checker pattern look terrible around the edges. Some would have let it pass, but I'm a stickler for details. I didn't even take pictures of it because I was that displeased with the result. So, I ripped it off and decided to stretch the vinyl on first and then paint the squares after. This was still a difficult task, but again, the upholstery spray adhesive that I used really helped me pull and stretch the vinyl around the tight curve at the top. I ended up with a much nicer result. It was still a pain to apply the vinyl checkered mask because I had to manually trim some of the pieces that bent around the edge.
Once it was painted, I installed a couple more brass inserts for the attachment of the pipe clamps. Worked like a charm. These are the same inserts that I use for my reproduction sturmey archer shifter handles. The only thing that I would mention here is that it's important not to go too heavy on the vinyl spray paint. My results on the backrest were not quite as crisp as the seat. Some of the paint bled under the vinyl mask because I was a little generous with the paint. I should have done a couple lighter coats. Still looks great though.
