B&D makes heavy duty saws? Well, maybe their 17 inchers...

No telling how old this monster really is. I started framing
apartments in '72, and we had one of these old B&D monsters out on the
job, NOT the DeWalt which was more common. It was old then, ran on its
own circuit (courtesy of the jobsite electricians) and we used it all
day long. The guys that ran it had been with the company a while and
they told me that it had been rebuilt several times.

We used it to cut the ridge angle on rafters, the rake on the rafters
where possible, floor joists, roof joists, and headers for build up.
Never saw it hiccup.

BTW, you should know that B&D still manufacturs a commercial, heavy
duty line of tools. When I was doing some inspections on a union job,
they all used the B&D line of commercial tools because they were made
in America. They were the only ones allowed on the job.
