Your indulgence please.
For folks with these machines:
I have been wanting a 12" disc sander for years and having just used
one a bit got
me on the hunt now.
I have almost all the makings for one. 12" disc, 1 HP 1725 RPM motor,
tilt table, etc.
Looking at catalog pics shows me various basic designs.
What I need to know to make or chose a kick ass model:
-What RPM is best?
-What should the table height be relative to the disc center?
-Any other subtle niceties?

Thanks & all the best,
RichD, Atlanta

Rpm is usually not something you have much choice of, determined by
safety considerations. Dust collection is nice. Being all around
heavy, etc is nice too.

I am going to pick up a 14" one next week, along with a dust
collector, if you are in Chicagoland, and are interested, let me know.

1,725 seems to be the norm for RPM.


-What should the table height be relative to the disc center?

Centered?


-Any other subtle niceties?

Electric brake?


A high-end veneering shop I toured half a dozen years ago had a 20"
disc sander and I drooled for weeks afterward.

I have a cheap one from Harbor Freight and have been plenty happy with
it. Keep in mind that if you get a 12" the real working area is less
than 6". If you're doing wood work, get the biggest disc you can find.
There are times when I wish I had a 20" but most of the time 12" is OK

That looks pretty solid.


If you are doing wood, 3500 rpm is too fast, and will burn everything.
Better to use 1750 rpm.

RPM is controlled by available motor speeds, not safety per se.

I do not know if I could lift one into my truck. Maybe I will have to
take it apart.

Good point. I will see if it is 1 or 3 phase.

My 9" disk is mounted to a 1725 RPM face mount oil burner (1/4 HP)
motor, tilt table above centre, adjustable guide fence, with the lower
half of the disk enclosed and vented to the dust collector.

Thanks guys.
I've seen a few old iron US made machines now and the table was well
below
center and the ends wrap around.
One more thing occured to me.
Reversible motor. No reason I can think of not to have this. It's a
great
feature on my 5" diamond engraver flat wheel.
When you have to use the right side of the disc and it's coming *up*
it can get
real interesting real quick!
