Hopefully this sketch will show what I mean: http://tinyurl.com/28q5u7g
I don't want to close off the bays as need air flow (& light) ... thought about putting in an acrylic sheet between the gallows brackets, just to prevent the blow in of rain. If I sloped this so that the lower edge was clear of upright posts, it should also provide a 'drip' to prevent much of the water ingress. i.e. as in sketch .. http://tinyurl.com/24jt8r5 Space between each support posts is 6' ... and there are multiple bays to do. Assume I use something like 10mm thick Acrylic ... I can easily manufacture side & top edge supports out of wood .... some ½" x ½" either side of ends & top, would provide location slot. The issue is what to use for bottom support ... i.e. along bottom edge. 6' is a long span ... what I need is something I can bond to acrylic to provide a drip, and if it is longer than sheet would also provide a fixing point to outer face of posts.
I having been mulling over using aluminum 90 angle section, anybody any better ideas ?
Also any other ides of acrylic sheet, or even thickness of it I'm proposing.
