Clean Edge Extruded
Cutting aluminum on a table saw isn't a problem, as long as
you have a carbide-tipped blade. But it does tend to leave a jagged edge (see
top photo).
But while cutting aluminum angle recently, (?) inadvertently cut through a
manufacturer's sticker on the work piece. Once the cut was completed, I noticed
the edge underneath the sticker was perfectly smooth.
Intrigued, a strip of electrical tape was applied down the
length of the next piece of aluminum angle (see bottom photo). Yes..... The tape
eliminated burrs on the edge, resulting in a smooth, clean cut. Now, I no longer
have to spend valuable shop time filing the edges clean
after cutting aluminum stock.
