Re: [bolger] Re: fitting polycarbonate?
- Sounds like you guys are mixing up polycarbonate and plexiglas (aka
acrylic). Polycarbonate is very hard to crack. You can beat on it and
bend it without doing so, and I certainly can't recall any troubles with
holes. It's good to use a slow feed rate, however, so it doesn't melt
and freeze and grab your tools suddenly, which can do a real job on a
Si señor. The stuff is tuff. Expensive but well worth it when the
characteristics demand it. We use it for signage purpose when we need
something to stand up to bored punk's abuse, for example. The usual
problem is machining the stuff, as it is formulated precisely to
prevent the same damages you are trying to inflict on it.
PET is another of these materials ( the same used for soda bottles) ,
although less rigid, and less scratch resistant.
Both should state the U.V. resistance warranty, as not all are
formulated for exterior use!
We cut it with a jigsaw with a DeWalt cobalt steel Extreme blade, ref
DT2144, for alu, plastics and fiberglass. These blades are great. As a
matter of fact, lately we tend to buy DeWalt power tools as first
choice. ( Standard Disclaimer : No relation to DeWalt... Bla, bla...)
