in the run up to Maker Faire OC, a few things were completed. The top was removed, and the stringers were glued into place as well as on to another.

Then the shade cloth was added. I used a dado 1/8” wide by 1/4” deep, and some 1/8” screen spline. It took about 30 minutes to work my way around, getting the spline fully embedded. After the spline was in place, I was able to chase around with a sharp knife, cutting off the excess, results shown below. This method withstood a trip in the back of a truck a bit over 40mph without loosening.

The night before maker Faire the seats were finished as well, some pics below. These are 2” high on the sides, 19x14” width and length, with 2” foam on top of the woven upholstery elastic.  

The next day the bike was loaded up!

and here it is at Maker Faire!
