Home Made Rivnut Tool
Watched the video. The guy knows his business. The fasteners he used a six mark grade eight. I just went through a dry run on the bench and it seems my useless hand thwarts ideas of adopting this my use with 10x32 screws.
Because I am planning on using wide flange nutserts in polystyrene plastic. I am going to need backing washers on the inside of the work where the rivet is drawn and bulges. That's going to take some fancy footwork to find the exact size US or metric flat washers that allows the rivet to bulge without interference and resists pull-out. As a thought I might try GOOP to help resist the nutsert from spinning. I am going to use Torx screws with large heads.
Why plastic?
Weight
Ease of drilling and use of rotary tools
A 12" x 14" box is insanely expensive even in plain steel and it is heavy. This is for use as a cover for battery chargers. Handles, feet, panel meters, switches, cords.
But the video has taken a solid hook in my mind. If I could find a 3/8" double box six-point wrench that has deep offsets at both ends, I can use a long long allen head socket head bolt (The screws are even stronger than grade eight). Maybe tack weld a six inch cheater onto both the wrench and the allen. This means two wrenches. Hmmmm...
