Jimmy seat

I always wanted a Jimmy Seat on my scooter. You know, like the one Jimmy has in Quandrophenia. Sometimes they are called ironing boards. Well, I also wanted a rear rack that folded and held a spare tire. When I got my Stella I found that no one makes a 3-in-1 rack with a tall backrest so I had given up on having one... Then, over on the LML Owner's Group of Great Britain forum, I spied a 4T with a 3-in-1 rear rack with a tall Jimmy style backrest. I wrote to Geezer, the owner of the scooter, and he told me that he built his tall backrest and bolted it to the low rest frame. We traded a few IMs and he told me how he went about it in detail. I was hooked, and had to do it!

So... I ordered a tall backrest cover from PK Trim to match my custom Black jack seat cover, and went at it:

First I made a cardboard pattern. I love cardboard patterns since they are free, and if you mess up you can just start over.

Once the pattern fit well inside the cover, with just enough room to handle the wood and the padding, I traced it into 5/8" furniture quality birch ply and cut it out:

After checking that the wood was indeed the right size, I used the cardboard pattern to plan the bolt holes:

Once I was satisfied with the bolt hole location, I traced the holes onto the wood, then realigned them, and drilled two, checked the second set and drilled them. The stove bolts were hammered in and the board was tested for fit.

I originally planned on using six stovebolts to mount the backrest, but once I got the four on there, it was obvious that it was not going anywhere.

Now it was time to turn the board into a back pad. I purchased 2" thick foam at Jo Anne's fabrics, traced the wood and cut out the foam with a brand new disposable blade.

Then rows of duct tape were applied to the front side of the foam, and I leaned on it hard, wrapping the tape around the board.

I had to apply tape twice to a few areas to get the shape I wanted, but it came out OK.

Next I stuffed the board/pad into the cover, and got it straightened out. It was do or die time: The bolt holes were lined up, and cut into the pleather with little x's

All that remained was to bolt the tall backrest onto the frame, using 5/8" D rings. I plan on buying 4 chrome 1/4" acorn nuts next week to replace the cheapo zinc plated nuts that are on there now, but other than that, it is all done.

This was done in two nights, with lots of planning, but turned out easier than I expected.

How much total did it cost you to make that in materials?

Let's see...

The wood was about $8, the foam was $9, the nuts and bolts and brackets about $6, but the cover was from PK Trim in the UK and cost me $80. If you can get a cover/make one, the rest is pretty cheap.

Great job with the seat! Where did you get the bolts/brackets? Those are going to be perfect for when I make a custom wooden crate to attach on to the rear rack :)

Nice job and a great looking scooter! The only things I don't get are the GS on the legshield and the yellow stand boots..

They actually are just D shaped clamps I picked up at Lowe. They come in many sizes, so measure the tube you will be clamping to before buying them:

That's an Adel Clamp. Normally used on cars to isloate the fuel/brake lines from rubbing on the frame.
