You have peaked my interest... I know that you can order "optical quality" polycarb which, as I recall, is very clear. We have some at the school. I'll check tomorrow evening and see just how blue it is. Mike |

I would use a sheet metal brake rather than pliers and, whichever method you use, please wear safety glasses! Mike |

I was just trying to give them a quick and dirty method to tell the difference. We have been at multiple regionals where we needed some poly carb but we have been given acrylic. ~Kirk |

I am sure that every single person who is reading this note owns some "optical quality" polycarbonate. This style of polycarb is extruded in a clean room and the molten plastic is pushed through a filter. Who can guess where this "optical quality" polycarbonate is used by everyone? (15 years ago, I was a co-op engineer at GE Plastics. The Mt. Vernon, Indiana plant extruded 1,000,000 lbs. of the stuff PER DAY back then. I can still recall the sweet smell of Methylene Chloride.)

oh, heck, I'll give the answer... it's a compact disc. CD manufacturers seemed to be the most concerned about optical quality. Andy B. |

Re: Working with Lexan
Wow... thats new. Though it does make a lot of sense, now that I think about it...
Does anyone have an idea for where a good place is to get this stuff? Lexan, other polycarb, or plexi even, though I know some of you dissaprove of it Last edited by TheAnsweris42 : 18-01-2006 at 12:00. |

Re: Working with Lexan
Your local Home Depot may also carry Lexan, I know ours does.

Re: Working with Lexan
Many teams will not have access to these methods, but:
Lexan (polycarbonate) is easily cut using a water-jet. Plexiglas (acrylic) will probably shatter if you try to water-jet it. Conversely, Plexiglas (acrylic) is easy to laser-cut, although it does create a stink. Lexan (polycarbonate) should not be laser-cut because its fumes are toxic. My team has one sponsor with a water-jet machine and another with a laser-cutting machine. We found out about the differences above through some trial and error. |
