Texas Parasol style construction

[plncraze]

I was looking over the builders manual for the Texas Parasol homebuilt and was intrigued by the method used to build the fuselage. It uses aluminum angle for the structure only it is modeled after a wood structure. The joints are solid riveted for attachment with the end of the diagonals filed down where they fit under the longeron so there is clearance in the radius of the longeron. The builder reports no problems. My concern was that if you used two rivets side by side they would work as a rivet cutter with the point of rotation being around the rivet with more friction.
After realizing that I cannot get wood as cheaply as metal where I live and with metal having quality control at the factory this might be an inexpensive
(relative to shipping wood across the country) means to build.
Any thoughts or experiences regarding this?
