I have several dozen old AOL CD's that I have kept just because I
figured someday I would find a good use for them. Well today I did find
ONE good way to use them. I needed a new filter for my old 5HP Sears
Shopvac. When I put it back together I couldn't find the old Filter
disc. I am afraid I accidentally left it on the old filter and it was
thrown in the trash ( trashday was yesterday). I got out my compass to
measure the size of the circle I would need so I could make a new disc
on my scroll saw and drill press. I just happened to have a music CD
laying on top of the computer and VIOLA the CD was almost exactly the
size I needed and the hole in the middle was the right size also. I put
an old AOL CD in place and I have been using the shop vac all morning
and it works great. Now if I can just find a few other things the old
CD's are good for. . . .
Thanks for the warning. I mean, ever since I found hair growing on my
palms I learned to take such cautions seriously.
Seriously though, I suppose all that snap crackle pop *might* come at
some expense. But why and how is it hard on a microwave?
Sigh... do you know what a Standing Wave Ratio (SWR)is? Do you know what
a bad SWR means to a tranmission tube? Have you read the manual about
putting metal in the microwave? Do you know that it's the metal in the
CD that causes this reaction?
Why do I think the answer to the above questions are no

I have an old huge Panasonic convection microwave that is still my #1 kitchen
appliance. Because it is also convection this thing has accidentally microwaved
tons of metal. I even miked a 10 stack of CDs at once, now that was a show.<g>
It works as well now as it did new nearly 20 years ago.

I haven't tried a stack of 10 at a time, but I'm sure it would be quite
Have you tried the grape plasma arc yet?
Nice show, especially if you have the lights off in the house.
Odinn - even boiling water in a microwave is dangerous
Try a marshmallow -- it'll swell up almost as large as a tennis ball. If you
have a microwave with variable power levels, the marshmallow will expand and
shrink, expand and shrink as the magnetron cycles on and off.

I keep my table saw blades on a wood dowel and space them with CD's to
teeth from touching. Also can use as spacers with a dado blade. Warren
That is a great idea Warren. Thanks
Somewhere online I saw a very cool (and apparently very heavy) lamp made
from a ~12" stack of these with a cold cathode light tube through the
middle. The light shines out through the edges for a nice diffuse effect.
I've been pirating junk from the net for ten years. I burn 3-4 DVDs a day now.
I collect it like stamps.
I have at least 6000 CD/DVDs most are junk now.
That would be a stack about 40 feet high.
I wonder if I made a light post for my front step how long it would shine
exposed to the weather. Could I drill out the center and put in a long

You can cut them and heat bend them into fan shapes that spin like crazy in the
wind. Scares away critters from the garden.
Most of what you have burned is "junk now" yet you still burn "3-4
DVDs a day"? I mean, we all collect and accumulate bits of crap we
find on the internet, but if we figure 4.7 Gb per disc, that's like 15
GIGAbytes of stuff per day! You are trying to set a record? What on
earth could you be collecting at that rate?
