| 1080.1 | a suggestion | MASTR::BERENS | Alan Berens | Tue Jul 20 1993 13:51 | 7 |
| Cut a 1" diameter hole in a piece of wood. Center the hole in this piece
of wood over the existing hole and clamp the wood (gently) to the
plexiglas. Enlarge the hole in the plexiglas with a fairly coarse round
file. You could try a hole saw guided by the hole in the wood, but this
would be much riskier, I'd think.

| 1080.2 | try this... | MIMS::PICKETT_K | | Tue Jul 20 1993 14:04 | 9 |
| Try this:
Secure a piece of wood to the back (or front) of the cover via
c-clamps. Start pilot drill in wood and ease down into the pglass.
-good luck!

Follow the previous methods mentioned using a board with the correct
diameter hole and then use a barrel stone on the end of a drill.

| The file meets the "on site" and "low risk" approaches, at the expense
of some labor. Sounds good.

| 1080.5 | .2 is right on | USCTR1::BORZUMATO | | Tue Jul 20 1993 15:05 | 9 |
|
.2 IS CORRECT, HOWEVER BEFORE CLAMPING THE WOOD TO THE GLASS,
YOU NEED TO DRILL A PILOT HOLE AND THEN CENTER IT ON THE GLASS.
THIS IS THE LOWEST RISK APPROACH.

| 1080.6 | be cautious | MASTR::BERENS | Alan Berens | Tue Jul 20 1993 17:49 | 9 |
| re .1 and .2:
Plexiglas has a tendency to melt when drilling or sawing (hole saw). The
melted chips can cause the drill bit or hole saw to jam with
considerable force, more than enough to break the cover. I have found it
necessary to use very low speeds with a drill press and lots of water
lubrication to cut a large hole in plexiglas or lexan. I'd be most
reluctant to try to enlarge your hole by drilling or hole saw. Your
skill, technique, and luck may differ.

| I would also place masking tape as best I could around the 1" circle to
help to prevent the piece from cracking and getting scratched. Would
it be possible to use a router on this?

I would use the file and take your time. You could just take the
door off the hinges and bring it to bench to work on.

I need to clarify something. My recommendation left something out.
I did not mention taking the door off.
I was under the impression......................
I have drilled and enlarged many holes in plexi and lexan.
Using a drill press at its lowest speed and very light pressure,
and of course a new or newly sharpened hole saw it will do the job
just fine.

| 1080.10 | Use the jigsaw. | MPGS::MASSICOTTE | | Thu Jul 22 1993 19:47 | 8 |

I've cut nice holes with my portable jigsaw, a fine scrolling
blade and on it's slowest speed, checking the blade temp once
and awhile with my finger.
Ya gotta go easy tho'.

I'd go with .8! A "rat tail" file and some time. It has to be the
safest way to go.

| 1080.12 | Two hole saw blades | SUBSYS::CHESTER | | Mon Aug 02 1993 13:49 | 11 |
| Try this. Use a circular hole saw with two blades. The first one should
be the dia of the exsisting hole. The second one the dia of the new hole.
Stack a washer or two between the hole saw blades so the smaller one
sticks out. It will work as the guide. Use water or light oil as a
lube.
I just use this methode to change two tranducers from 1.5" to 2".
Worked ok for me.
