I take all your objections to making a table saw out of a circular saw and raise you one Mirock.
If you think it's a bad idea, think again. His system is genius and solves a great many issues inherent with a table saw, I'll be very surprised if there isn't a commercial version of his system at some point in the future.
Add to that a home made cyclone pre-filter and your extractor filters will.last a lot longer.
Dust is a menace. It can give you pneumoconiosis. There is also the possibility that you csn become sensitised to the formaldehyde which occurs naturally in materials such as pine - so always wear a well-fitted mask as well
I used one those circular saw/ table saw contraptions in job more than 10 years ago. It was an awful thing- a Wolfcraft sheet metal work bench with a cheap Stayer saw bolted to the underside. It did work, but was noisy, fence was terrible and was not simething you'd have any confidence in. I ended up make my own track saw sled out of MDF and used this for all but the narrowest of rip cuts. This was in a picture framing workshop.
