This group has debated Rivnuts extensively. One poster claims nobody
should install a Rivnut unless he has access to a complete machine shop.
Others with more experience have said that the installation is easy for
anyone with normal mechanical skills.
That would be SMS (Steven Scharf) on one of his web pages:
Since I've made a mess with all the available technologies, Rivnuts
(steel and aluminum), brazing (steel), TIG (aluminum), and epoxy glue
(plastic boss on aluminum), I'll remain neutral on the matter.
Hint: Use steel Rivnuts on steel frames, aluminum Rivnuts on aluminum
frame, and plastic straps or clamps on CF (carbon fiber).
One can only suppose that those "dumb asses: that manufacture rivnuts
deliberately make their product in a number of materials :-)
And, it might be added that not knowing what you are doing is not
limited to bicycle maintenence :-)
