Re: solar melter/ furnace coming soon!
I have heard of this but never played around with it. I am looking forward to the videos.

I've had some fun with a projection tv lense. It's just hard to aim and keep from getting mangled in my messy garage.

Re: solar melter/ furnace coming soon!
I've had a 12x12" lens for years -- Came with a warning "not a toy"!!
Serious heat and you can't stand to watch the beam at focus. Welding shields sure help.

Re: solar melter/ furnace coming soon!
Living in Milwaukee, I'm lucky enough to have one of American Science and Surplus's/JERRYCO's retail outlets in my town.
I had a 12"x12" Fresnel lens that was a take-out from an overhead projector.
I remember drilling through old golf balls with sunlight with that thing.

Re: solar melter/ furnace coming soon!
The bigest cheap magnifier I found is a Carson bigeye 5" plastic decent lense.
I use is to solder under.
Burns alot better in Fla than here in Mo.
Sun power density magnified =50W^2cm , or .2W^2cm regular.
Med. supplys sells 8x10 freznel for $5
I'd like to make a big CPU aimed helistat field!

OOps
sunlight is .05W^2cm. Think I read that in a laser book or popular science mag.

More links to these products guys please!! I want one!! 
I built a "Solar furnace" from a fresnel lens back in the 70s - I used to melt lead with it, among other things.
Got it at Edmund Scientific - looks like they still sell the kit, but I'm sure you can find them cheaper.

That Bigeye magnifier is $10 at opticsplanet.com CHEAP!
Google "visual aids" to find a cheap freznel maybee.
I got a 9x10 at a medical supply dotcom
