Thanks.
Now making 26 and 30 and 36 inch diameter reflectors. My Homemade ballasts also seem to all be working so far. Of course my scientific method of checking is limited to digital volt meter and comparing data to specification data of actual products and performance parameters. Also learning to use the digital light meter, which so far acts like the big searchlights are too bright for it to accurately get a "close up" reading. Will work on this angle too.
Use an English Wheel to make these. Pretty easy.
Harbor Freight listened to past English Wheel criticism and made some important changes, making this into a great product.
One can make a huge variety of compound, complex, or just simple curved metal products such as motorcycle gas tanks, car fenders, hoods, etc., with minimal set up, using a simple set up of; check, shaping, templates.
My goal is to make the 38 inch Interrogator act much like the 50 inch Monster, without it's enormous size, yet with the metal reflector should produce a 'better' beam.
