Which Plastic

Mats J · 26th January 2005, 11:56 PM

If I wanted to make a dipole with a plastic baffle, AND have the baffle be an opaque (sp?) color, which type of plastic sheet should I buy. Mind you, it has to also be machinable with standard "garage" wood working tools.

Corian or something like that could be quite cool.

Depends on allowable cost, and method of assembly - do you want to bond parts together or fasten with screws? A plastic supplier from the yellow pages should be able to tell you what materials, thicknesses and colors are in stock, and will be able to cut your material to the part sizes that you need.
Here's a place to look at...

Cast acrylic is much much better to cut and drill than extruded acrylic.

While Googling for plastic one day, I found a web supplier listing dozens of different plastics and their primary characteristics on one chart. If you can find that page, you'll likely find your solution...and be able to order it at the same time.
