Title: Rib gussets
Post by: DEDean on December 07, 2015, 11:05:38 AM: Okay, got a stupid question ('cause that's pretty much the only kind I ask) about the rib gussets on the DE. I looks around the forum for an answer, but couldn't find anything. Please forgive me if this has been asked before, but does it matter which way the grain, in the 0.8mm plywood, runs? And if so, which way should it run? Parallel to the cap strips? Perpendicular? On an angle?

I got a team together and we're building my DE as a chapter project. And a couple of the guys are super concerned about this.

Thanks for your input.

This question seemed to have had a consensus back in 07 on the old list...

Also, it stands to reason if it is really "ply" wood it has different grain orientation in each ply.

LOL, well I had my laugh, because I asked some of the chapter members, (engineers and a&p), and a master A&P the same question. The answer was no, not on such small pieces.
