Very glad to hear I was able to help someone else out for a change. It's usually the other way around is seems! If you end up doing it, let us know how it turned out.

I most certainly will! I'm looking into free blowing a new canopy for my CH200. I have a fairly good idea what I'j doing, but if anyone has any information on this subject they'd like to share, I'd sure be glad to hear it!

I am looking for plans or instructions on building an oven to form plexi over a form. I have tried the link in the first post, but it takes me to a different website.

Thanks for any help.

I built a 4x8' oven with waferboard and 2x4s. It is heated with a 2000 watt electric barn heater and the broiler element borrowed from the kitchen oven. Should be about 4000 watts. The oven is insulated with about 3" of fiberglass. I got it up to 300 degrees, but 280 seems to be sufficient. Takes about 50 minutes.

Today, I installed a fan to help control hot spots.

To all,

I'd like to know more about the oven and what you are going about forming the plexi. Puttiing the plexi in a frame and pulling the plexi over a mold or ??. Will a hot piece of plexi conform to a mold?

I need to make an oven and a system to stretch the plexi over a mold to make the side windows on my plane. The windows are about 20 x 32" and a compound curve.

A long time ago I saw this done, but I can't remember just how to do it.
