Progress update.
As of midnight last night I finished the design of my nose and tip plates. It was a little more effort on my autoCAD than just designing a nose plate because the tips have a different folding situation and I wanted to make all six pieces identical, for my labor efficiency when it comes time to fabricate them. With these plates the glider will be able to be folded with the six foot tip tubes in place. The diagonal brace for the tip will need to be removed or at least disconnected at one end, minimum.
Next design effort will be all the hole positions on all the airframe tubing (I've already done the portions that go between the plates). When it comes time to actually drill the holes I'll be using John Heiney's method of a digital level for setting angle differences between hole positions along the tubing.
The name is Puffin not Puffer. Puffin is a low aspect ratio bird that flies well.
Please don't hijack this thread for USHGRS discussions which have nothing to do with my basic trainer design thoughts, that discussion has its own threads, go there. Presumably, anyone earning a rating with the Puffin will get that rating listed in USHGRS.
