Both of my hand circular saws are worm gears, and I don't want to take them out of the general-use rotation by rigging them up as track saws – plus, they're heavy, and I want something lighter – so I'm looking at purchasing a cheap but decent circular saw for use as a dedicated track saw for breaking up plywood.
It needs to have/be:
7-1/4" blade
120VAC (IOW not battery/rechargeable)
easily replaceable brushes
cheap
preferably a model that has zillions of copies out in the wild that I can cannibalize for parts if necessary in the future
Anyone have any recommendations for new or used models? I found a $28 jobbie at Walmart but it looks like changing brushes would be tough.
(I started with worm gears and I've used worm gears almost exclusively ever since, so I don't know much about the sidewinder type, but that's what I'm looking for...)
Thanks in advance.
