The whole and main point of my experiment was to (1) recognize the need, (2) a cheap sacrificial edge, (3) being that it would be sacrificial, that it would be easy to install and uninstall, (4) easy access to replacement, (5) no nuts and bolts or the need to weld tabs or any other type of permanent fastening, (6) CHEAP!!, and finally (7) does it do at least 75% of what the expectations were.
We can all probably agree on the theory we are talking about here, the only real question is in the practicability and durability of the material used.
So, where are we at here? #'s (1), (2), (3), (4), (5) and (6) conditions have been met. And I'm exceptionally pleased with #6 = $4.98.
As a side note, I'm secretly hoping that in the same matter, as when I got the snow blower, it was a couple of years before it was needed. So I'm hoping that maybe this experiment will not be tested this year but things aren't looking very good.
