Being by yourself will help a lot. If a friend comes over and runs something you’ll see a huge drop. As such, if a friend does come over, always choose the closest machine for a bit better collection.

The whole CFM things aside, a three horse unit is the smallest unit I’d expect to handle two machines well, keeping in mind the things we touched on, like long runs and bends.

As to the table saw, it is a tough beast to tame. How tame you can get it has a lot to do with what you are doing. I suspect much of the related stuff is already known to you, but I’ll drop it for those who might not. For example, cutting out on the edge of a board really kicks up a lot of dust. I have the same problem on my bandsaw (which is why my circle cutter goes all the way to the support arm).

I do note that when my upper collector is as low as I can get it, it REALLY cuts down the problem. However, to use it all the time requires using holddowns and chaser sticks to push stuff on through.
