Tom:
As an interim measure, you might do well to pay more for smaller quantites
and figure out what you do the most. I buy them in 25-50 packs and get
fairly good price breaks even at Lowe's or HD. Generally speaking:
- #80 is the most aggresive I use, mostly for stubborn paint removal. I
also use these to shape wood on some sculptured projects I build.
- #120 to #150 gets a fair amount use as I start finish sanding and I
probably use as many of these disks as any other grit.
- As I move to the #220 grits or finer I use sheet paper on a more gentle
pad sander or a block, depending on the job.
I bought so many #80 disks several years ago I will probably have them
around most of my life, if the paper doesn't rot off first. Be careful
using aggresive grits - some random orbit sanders can remove a lot of
material fast - too fast. As I noted, coarse grits on a peppy random orbit
machine makes a pretty good wood sculpting machine.

You will use any grade you can get, but ROS 120 and 220 are the most
usable grades in my shop.
I use 80 and 60 grades on Sticky pads, they do not go anywhere, you
can not change the pad and reuse again.

That depends on what you intend to use the sander for. BUT,
Mine is a PC right angle 2 hand ROS. I use it for initial for over all
sanding after assemble to insure joints and unions are smooth. I finish off
with a PC SpeedBloc finish sander.
I use 150 grit 99% of the time on the ROS. I have used 180 in the past but
tend to only buy 150 now. You might start there and maybe in a smaller
quantity and go from your own preferences.

I generally always stock 100, 150, 180, 220, 320. I might have some 80 too.
You will probably find you use more 100 and 150 than the others. The 100 or
150 are usually your first grit used, and you must do a good job with those
before moving on to higher grits. If you do a good job with that first
grit, running up through the other grits goes really fast.
Sanding tip: Use sandpaper like it was free. Consider hypnosis.

I usta do that when I was the GM for a 3M Distributor. I got free rolls of
250 count paper quite often. Still working on some of those rolls years
later and oddly this PSA paper still sticks like it was new w/o protective
backing stuck to each sheet.

120 and 220, I think see the most use.
I recently got a 50-pack assortment from amazon: 10-each of 80,100,120,150,
and 220.
It's a great starting point to figure out what you will use. $16 is a good
price IMHO.
I have been generally pleased with their longevity

Personally I find that I use 220 most of the time.
I second the suggestion that you get a sampler. If you go to
<http://www.woodworkingshop.com/>, pick "abrasive disks", pick the type of
disk you need, and look at 50 packs you'll find that you can get 10 of each
grit from 60-400 for about 40 bucks and shipping. If you're using a finish
that tolerates stearate they also have stearated disks up to 1500 grit.
Unfortunately they don't have a sampler of the very fine grits, at least
not that I can find.
Suggestion--keep three packs of each grit you use on hand (if you're a
production shop I know you'll be keeping a lot more than this--I'm making a
suggestion for someone with a home shop) and when you use one up, order
another immediately. That way you're never in the position of using that
last disk well past its useful life because it's the only one you've got
and you've always got at least one full pack on hand.

Mostly what I use are a 100 grit, followed by a 150 or 180 and then a 220.
I have some 60 grit that I use when I screw something up like a butt joint
when making a wider board. That is getting to be less of an occurrance now.
I would say that I use 100 grit about 2 to one over the others.
Also, I recently started buying the Norton 3x brand of disks. WOW what a
difference. They cut fast and last a long time.
