Servicar sportster trike: rear frame
When I bought my trike, the rear uprights that supported the bed were welded to the frame. Unfortunatly, this trapped the rear axle in the frame. I wanted the new supports to be removable. What I did was find some 3/8″-16 coupling nuts that barely fit inside the 1″ tubing that made up the frame. I tapped them in place with a hammer and then welded around them. This allowed me to bolt on the uprights.

In the front I welded the cross piece to the frame, but did the same trick with coupling nuts. The cross piece is 1″ square (the rear fender brackets will bolt to it), so I needed a bigger coupling nut (1/2″).

So here’s a shot of the whole bed frame:

I’ll probably just make a flat bed with some boards, maybe redwood.
