Thank you for the article "Kitchen Window". It gave me a couple of ideas. I have a small forced air propane heater I use to heat my garage during the winter. I think if I made some sort of box to hold the hot air I could use it as an oven. Also I like the idea of using air to "blow" the plexiglass. That would save a lot of labor associated with making a male mold out of wood. I will have to fabricate female curves to match the curve of the top of the wing and the front and rear cross pieces, but I think that will be less work than a male mold. Blowing it also eliminate my concern for protecting the plexiglass from scratches when using the male mold. Thanks for the ideas.
