I have read most of the messages about converting a (belt-driven) table
saw to a disc sander. I have an older saw collecting dust in the
corner (it's worthless as a table saw) and am considering one of the
sanding discs for infrequent use. I expect it to ruin the saw or arbor
bearing over time. I could care less.

The thing I am not clear on is RPM. My motor turns at 3450. The
grizzly disc sander says it turns at 3450.

What should the disc spin at? It's just a pulley choice. The messages
about the saw turning too fast and burning up wood don't seem clear. I
assume this is because people are using the same pulley ratio as they
were with the saw blade, which is faster than 3450?

Saw speed works for me. I did burn some oak on the first try; but a
little care goes a long way toward eliminating that problem. Worry
about the pulley ratio if/when you decide the speed is actually a
problem.

Yep, what you said.
Just take care and regulate your pressure and you should be cooking with
gas

How do you get a saw to collect dust? People spend a lot of money on
other machines to do that - my saws just seems to produce dust.

You can slow down the burn rate and or surface speed by simply sanding
closer to the center of the disk rather than the outer edge.
