Please do not laugh, the silver instructor at UCSD uses a Harbor
Freight device, cost on sale $20.00 or so, not on sale $40. Her
admonition to every student, do not force this machine, go easy and
it works beautifully. Force and break it, it now belongs to you and
you owe me a new one. I have yet to see it replaced and most of us
now own our own. Yes I do.
She teaches a lot of rivet connections and tube settings. This cut
off saw is in frequent use.
