While that would be true of new CDs. I have hunderds of old software CD's available to me. Paul

True, but I have a feeling that even with hundreds your only going to get a relatively small window! It is interesting though, please let us know if you try it.

main thing the concerns me there is 'old' remember how old AOL CDs used to shatter into thousands of pieces instead of breaking into two?

If you want to come to my shop you can have lots of free poly..... as long as you aren't fussy.
I am always scrapping old manufacturing equipment and have no use for used polycarb.

You got an amphib car?

The amfibious car is not the problem. There arn't a lot of service stations in the middle of the Pacific. I would have to hire a tanker to escort me. Still for some free polycarbonate, with NZ prices you never know.

not too bad... 12$ for a panel, maybe attach it to a aluminum bar (thin, 1/8" thin?) and rig up something to your table.

Hope that helps. You could always buy a grizzly one,

p.s. sorry for thread jack, but for lubricant: The only reason you would want it water-tight is to keep it from getting on you, correct? do you have to clean it off of your machinery after use of the lubricant? it doesn't make sense to me how much lubricant is used but i haven't seen a good way to drain it in a home workshop...

/end rant.

Hope this helps!

When buying polycarbonate cut-offs be careful. Some polycarbonate used for glazing has an abrasion resistant coating so it does not scratch as easily as uncoated polycarbonate. This coating makes the polycarbonate much more brittle; not as brittle as acrylic but enough that it is possible to shatter it with a good hammer blow. Uncoated polycarbonate can withstand hammer blows.

Hmmm....Im not sure if mine has this coating or not, but the folks I bought it from have two 8x8 cnc routers, and they specialise in plastics. I told them what it was for, so I just kinda assumed that it is the correct stuff!
