"$3 worth of steel, a hundred for the dies to stamp the holes and a few grand for the press to do the stamping.
Even a 1 ton arbor press is gonna be over $100. So $3 in steel, $hundreds in tooling.
$6 nylon strap sounds like a good deal in comparison."
ASSuming one is limited in their creative abilities to the point that making a hole in a $3 piece of steel is only possible by using a press and die, I guess I see your point.
Why a drill press, hole saw and a little file/die grinder work or a hand drill and a jig saw with a metal blade or even a plasma torch are not viable options that occur to you as less costly options... I do not know.
