typo ? material would then be vertical.

The problem with this is that if one is cutting out smaller parts,
they will fall. either into the cutter or away from the cutter.

Also, larger parts would, as I used to say as a kid, falldowngoboom !
maybe a little, but possibly a lot. some means of addressing large
parts in and out would be required. My first thought is a small
vacuum hoist. should not be too hard to rig up. and one can put pins
in the table after cutting

But, it is not a new idea. there is a guy in I think France, that has
a vertical, slight angle to hold the wood, CNC machine. he uses piano
wire on threaded rod instead of belts or gears.

There is another guy who hangs his in the garage and lifts it to put
the car in or to walk around.

Another idea mibgt be to have the table so it can tilt up and offer
more cleanance when not in use.

I like the idea of thinking out of the box.
