No baffling, seems ok without it since I painted the inside black. Just found a perfect fit dust cover for the dew shield, the base of the Fereo Rocher "Bell" I bought Kym for Valentines Day. Someone is looking after me
Spent most of the day making the dew shield, that colourbond is springy stuff. Had to bend it around a 100mm pipe to get the initial curve, grind off the paint and zinc coating on the first 12mm of the overlap before it would take a silver solder weld, then squeeze and push it into a tube shape with me thumbs. Gee, I miss the tools that were available when I was working, could have knocked it off in an hour or so.
