I realized that wood, although works for a lot of people, might not be the best material to use. A electric short in the projector or possibly melting of something could cause wood to ignite. Is it not true? I wouldn’t leave wooden projector unintended, especially for the first few time. Maybe I’m just paranoid.
So I started looking around. How about something like Polyethylene (the stuff that they make cutting boards from). HDPE (for High Density Polyethylene) has 295 deg F forming temp. Nice thing about it is that it can be cut with wood cutting tools, heat formed, shaped and welded. It might be bit heavy, though.
Other ideas?
