Ok that confirms what I was thinking. I went ahead and made the spars longer with wood, ( not assembled yet - no plywood cut). But in the "leftover" prints I got of DR Deans there were templates for the 48" 50" and 33" - two of the 48" were already cut out of birch ply. ( I was thinking the 50" were an option.?) And that the 33" were for the end. I made my spar pieces 3.5" longer as I was not going to have 8" of foam on the ends, but about 5" with the lights mounting to the plywood spar. But I take it then I should not use the 33" on the end. Guess I will have to do the download and get them printed out somehow. Thanks Mark as you must be a mind reader.
