The sun cap on the DFXL worked out pretty well. So I thought I’d build one for the WAW. I like the shape of the DF’s so I started with that. It was easier to mount on the WAW than on the DF since the WAW provides very nice clamps on the inside sides of the manhole cover. Here are some photos:

I’ll need to do some testing to make sure that it provides the shade and cooling without hurting the performance too much.
