I'm primarily a wood turner, but dabble in other stuff such as coffee tables.
For a long time I've looked for a nice big disc sander. Without the room for a double disc monster and not a whole lot of budget, its been tough.
Until last month!
I found a 32" disc sander, very basic, but its all I need - almost...hence my questions.
Its just a 2" shaft, about 26" long, 2 very large babbitt bearings, am 8" flatbelt pulley, a 20" cast iron plate and a 32" spruce plywood disc mounted to the plate. (sorry, no pics yet).
This will be driven by a spare 3 hp, 3 ph motor and a spare VFD for starting and speed control.
The plywood is pretty hacked up and will be replaced with a birch ply disc. But only 30" in diameter, since that's what I can order more easily.
It will get mounted on a spare bench, so no cabinet will be required.
I'll also build a guard and dust port similar to this https://woodgears.ca/sander/disk_sander.html
What it does not have is a table, and I need to build is a table.
And before I make it too complicated and blow my brains out, this is where I could use advice.
1 - most sanders have a table at or close to the midpoint. But some allow the table to be raised or lowered.

Whats the intended use for this? OK a larger area is open....
2 - Tilting table - unless I sand compound angles, is there any point? It makes the mechanism a lot more complicated. I will likely add a slot for a mitre gauge.
3 - the disc guard generally wraps around the top, but many leave open slots near the table, presumable so you can work off the edge of the table. Ex: http://www.vintagemachinery.org/photoindex/images/14601-B.jpg
If anyone a good link to a DIY site, that would be great as well.
