Hi Dan, I love the idea of using your saw to make circle cuts! I have the same saw you do. Robert Veach

What is the difference between these round type shapes versus the rectangular shaped one's?

@dogknobber It wouldn't be as good as a glass one. Plexiglass is a lot softer than actual glass so is more prone to deformation, meaning the image wouldn't be anywhere near as good.

i wonder i9f this plexi glass is good enough to make a reflector telescope with?////

could it be better to use gasoline or other solvent to "melt to shape" the plexiglass?

Nice job, Dan. I did something similar with a hand jig saw and a flat shim stock bar, but it did not turn out half as nice as yours. Can you get away with using a standard blade, or do we need one of those fine tooth finishing blades? And for the poster asking about stainless steel, google is your friend. Dan would just be googling your question anyway. SS has too high a heat range for conventional oven to mold it with heat. However, if it is that thin, just mold it like aluminum foil

The shape is parabolic, meaning the reflection forms a parabola.
