It was fun to rivet this all together. Plans called for AN470AD4-5 for most side rail connection but 4-6 was a better fit so I used those instead. You often find in the plans where the called out rivet is just a little too short for a nice shop head. Split all the hinge pins in half and bent the end 90 degrees as a handle. Remember to heat the bendable portion cherry red with propane torch and bend while red, not while its dark or you risk snapping the bend off.
