I liked the idea of adding a top box to my F3s using the rack from the F3 police model, but when I ordered that rack I was informed that it was on back order until December 19th or later. I decided to make my own using 1/4" aluminum plate.
I used 6" x 24" cut in have for the sides and 12" x 24" for the top. I also placed 1 1/2"OD x 3/4" ID x 5/8" thick aluminum spacers stepped drilled to fit on the frame brackets where the hand holds were mounted. This provided a larger support surface for the back of the side plates (I believe in over kill).
All material was purchased from McMaster-Carr.
I cut the 6" x 24' in half as they do not sell a 6" x 12" I then drilled the mounting holes and bolted them on. I then placed the 12" x 24" plate on top and using a marker made the edge lines for cutting it down to fit the angle shape. I also marked the side angle on the side plates.
After cutting all the pieces, and since I do not weld I cut some angle aluminum I had and bolted the 3 pieces together and laid out the placement for the box mount. I noticed that the top plate was over the seat area so I made a cut to clear that. Once all the holes were drilled for the top box mount I than took it to a weld shop and had the 3 pieces welded together.
I finished up with sanding and painting.
I added a brake light under the back mount and LED running/turn/brake light to the top box and ran those wires out the front to a quick disconnect so I can remove the box and carry it into the room at night.

Isn't it weird that in AMERICA our flag and our culture offend so many people...... but our benefits don't?
