OK, the ONLY reason I'm asking this is because the Woodworking Gods
didn't have an answer, and I've not ran across anything in the arhives,
or googling, that could give any answer.
I'm at the point where I could really use a disc sander. I've got
a little combo, with the 1" belt and 5" disc. For the purists, it's a
little HF model, and runs fine. It's handy, but too small. So, I plan
on making one. I've been advised to make it with a 9" disc, so I can
cut discs from sandpaper. That sounded like a pretty good idea at
first, would save money on discs. But, I'm not at all sure it would be
large enough, plus, I'm not going to be using it every day, which means
a disc should last me a good while, so I don't mind springing for
sanding discs. Been thinking about using the velcro type.
Anyway, found a site that sells 24" sanding discs. A 24" disc
sander would be excellent. But, as I really don't have the room to
spare, figure 12" would be more reasonable, and I've found a couple of
cites (yeah, I know, it should be sites. Hehehe) with decent prices for
sanding discs.
My question: Is there any advantage to using adhesive discs, or
spay adhesive to stick the disc on, over the velcro type? I haven't
started on it yet, so can go either way, and don't need a today answer.
It'll be a plywood disc, if that makes a difference.
I've already said I'll be making one, so unless you've got a 12"
disc sander, that works, and you're willing to send it to me for
postage, I'm not interested in buying one. I've got several motors,
supposedly unused, and it's not rocket science to make one. Besides,
it's more fun.

Not if you plan on switching the disc before it's time to replace it,
in my opinion. I've got the Delta 9" benchtop ROS. It comes with the
velcro disk, along with a rubber pad that has velcro on one side so you
can stick the adhesive discs to hit.
I hate the adhesive disks. They're a PITA to put on, get off, handle in
general especially if you want to switch grits.
Now, if you're building one, you may just want to cut the same number
of plywood rounds as the grits you plan on using and swap those in and
out. If you do that, the extra cost of the velcro discs probably isn't
worth it in the long run.

Not sure on that yet.

The little experience I've had with them, I tend to agree.

Yeah, I thought about that - after I posted. But, for what I want,
and would be using it for, I'm not sure if I would be swapping grits. I
won't be needing to take off a lot of wood, and, while it needs to be
smooth, I won't need it to be glass smooth. So, I'm thinking I'll be
sticking with just one, not too coarse, grit.
I just find that cleanup of the adhesive is such a PITA, that and
getting the disc to stick right. That's a couple of the reason's I'm
thinking velcro. It's not like I'm gonna be going thru one or two a
week, so I'm not real concerned about paying out for velcro discs.

Then I'd say go for the velcro.

A friend has tried velcro and contact cement on his disk-&-belt
sander, and swears by the contact. Seems the velcro can creep & gives
you ripples in the disk, which stuffs up the disc - I didn't ask what
happens to the velcro part. Of course this is on an aluminum disk, so
he can splash on solvent & scrape the old worn out disk off with the
glue.
The main failing of MDF is that it doesn't like water, but I haven't
tried it with volatile solvents like you use on contact.

Don't think I've ever heard of velcro creeping on a disc. I wonder
if just heavy use would do that, or even light use, over time. I'm not
going to be using it for more than a few minutes at a time, and probably
not even daily. I would think the paint Traves suggested would take
care of any solvent woes, possibly just any paint. Never worked with
MDF,so unfamiliar with it.

Heya Joat,
i built one of these about 5 months ago for something to do, and while
i cant say mine turned out great, i can tell you what possibly not to
waste time on during your planning. . .
make your disk from 2 layers of MDF...plywood does not spin real nice
IE: unbalanced due to all the voids...was mistake #1 for me
trying to get the paper to stick to the disk was my second
adventure... do yourself a favor, and once you get your disk made and
able to run it on the arbor, true it up with a block of wood wrapped
in sandpaper. once you get that done, get yourself some of that
rustoleum hammered finish paint. i used the spray on stuff myself.
it cures real hard, and allows you to get the PSA backed disks. not a
real leap in price, and much easier to apply than spray
adhesive/velcro IMHO
its an ongoing project here, so let me know how yours goes, and i'll
do the same.

Hmmm, what I was thinking of was 2, maybe 3, chunks of plywood
glued together. Figure that would cancel out any voids. Hadn't thought
of MDF.

<snip>
That's one reason I was considering the velcro type.

I'd been thinking I'd need something to make a smooth, glueable,
surface.
What I was thinking about the velcro surface, it should only be a
one-time thing, and make changing discs easy, if I decided to change
grits.
I'll be putting updates in my projects section, on my woodworking
page, on my web page, until it's done. Then I may put it on my things
I've made page. But, I'll try to post an update here too.
