I built a large mirror base (5' x 5' x 14.5) to make someone disappear. Because of extensive touring, I used plexiglass mirrors. It is slightly bowed, and it ruins the whole illusion. The reflected wall is visibly distorted. I backed it with 1/4 Baltic birch, and then installed aluminum supports. These steps helped, but the problem persists. Has anyone had similar problems with plexiglass in mirror boxes? How do you solve this problem? Any help would be greatly appreciated!

You can't. That's a HUGE piece of mirror...

In order to get a good reflection, you need to use glass.

Protect it the same way...but with 1/2 or 3/4 ply, and you should be all set...glass is more durable than you think.

Although it will add more weight and expense, 1/4" glass will flex less than thinner sizes. That, plus makeupguy's recommendation will make a "touring" piece. True road apparatus is generally more solidly built than the counterparts used by part-timers. If you've ever seen a piece of apparatus after a couple year's worth of touring, you'll understand why.

Hey Brock,

Where do you live? I have seen your show twice. Obviously you operate out of my area, or at least close. I really liked your show, except for one thing.

Rock on.

You might consider mirror-finished stainless steel to avoid breakage trouble on the road.

Thanks for the advice. I thought that it might be solved by using real glass. I should clarify that there are two panels that are 42" x 14.5". I am concerned about the weight of using 1/2" plywood to back the mirror. This prop is already outrageously heavy (it is basically a small stage with a mirror principal underneath).

I am aware of well-built props lasting longer. I have a Gaughn Origami that is 10 years old, is transported assembled without a case, but it is in great condition. I have a beautiful Owen's Phantom Cage that is 1.5 years old, but there were some things that I scratch my head and think, "Why did they do that?" (For example, cheap chair casters set into a block of wood screwed into aluminum angle, all to hold a prop that weighs 200 pounds!) I had to replace the casters within the first 3 months I owned the prop.

Cliffg7, I live in East Long Beach. I'm glad you like the show (except for that one thing?!).

Hey Brock...

Baltic birch plywood has more layers and is thus a lot more rigid than conventional plywood. You could use thinner ply and save some weight.
