The windscreen I sketched out at Permalink #455 is in progress. I mocked it up first with PVC pipe to get the dimensions. Then I tried strips of redwood. Better, but the third attempt is curved metal strips intended for putting 1 1/2" radius edges on sheet rock.
I'll cover it with 4mm poly for photos. Ultimately it should be Lexan or rusty perf metal with a flip-down hatch like a scout car.
