....and I'm using the biggest free Fresnel lens I could find.....
I know it will ignite a picnic table almost instantly...
I'm building a aluminum frame and stand. It will be able to turn 360 degrees and tilt 180.....the tilt axis will be just under the focal point.
The focal point will fire upon table in the center of both axis....
The question...What do I put in the middle of the focal point?...a dutch oven on a turn table?....a block of iron about 1" thick and the size of a burner?
Should I completely enclose the sub framing in plexiglass?
suggestions are appreciated....
BTW.....if you have an old rear projection TV that stops working....rip the front off.....there should be 2 screens...the front is a linear diffuser....and right behind that is a Fresnel Lens.....as big as the TV picture....
