I picked up a heavy-duty Makita chop-saw at the dump. It is old & weighs at least 50 lbs. It is not a sliding type, just the basic chop with miter table. It needed some fiddling with the switch but runs fine now. The miter feature is broken though and it needs ~$50 in parts to get back to normal and is stuck @ 90-degrees. My thought is to make it into a metal cut-off machine. By seat-of-the-pants it seems to turn at similar RPM to chop-saws I've used previously.
Any downsides on this idea?
