Thanks..I sand at the last speed I used while turning and have yet to change
the speed to slow. The wood doesn't get hot because I don't keep the paper
there long enough to burn as I'm changing from 100-120-180-220-320-400-800
until a sheen shows. ...

The cloth piece behind the sandpaper really does do the trick. I'll try the
slower speed anyway just to compare the finish difference (or non
difference).

On some woods, you can cause heat checks in the end grain from
overheating. My rule is that if it's too hot to continue sanding, then
slow it down.

Years ago, a regular to this group, Lyn Mangiameli, discussed slow speed
sanding. After I tried it I was a convert - I now rarely sand above 500
rpm - and oftentimes it's much slower depending on the work diameter.
I'll see if I can look up the thread and post the link.

Tips fer Turnin': Place a sign, easily seen as you switch on your lathe, warning you to remove any and all rings from your fingers. Called degloving, extended hardware can grab your ring and rip it off your finger. A pic for the strong of stomach: www.itim.nsw.gov.au/go/objectid/2A3AC703-1321-1C29-70B067DC88E16BFC/index.cfm

Besides, rings can easily mar the surface of a turning as you check for finished smoothness.
