I like the way you control your windings with electrical tape.  I do the same thing with little tack welds of hot glue (easy to remove) but I think your tape looks better and does the job just as well.  Nothing like 300 winds of mag wire coming apart and looking like a rat's nest to get one a little peeved.

Jeanna has informed me that the ease of winding the large toroids I was so looking forward to was not to be as I ordered and receive my 2 1/4 pound mag wire spools from go brushless.  She has told me that the larger spools will NOT fit through the toroid's large ID.  Damn!  I was so looking forward to easy winding.  Oh well, that's how it goes.

Toroids due in early next week!

Each turn takes 2.3 inches of wire. Cut the length of wire you need and wrap it around a small diameter tube (you will need about 12 inche long tube). Then thread tube through toroid. Goes quick and no tangled wires this way.

Thanks, that is a good idea.  I was already contemplating cutting the flanges off of my spools to see if they might fit then.  Your way sounds eaiser, and I also then get to keep the empty spools for another project.

Suggestion for how to compare bulb brightness. Put bulb vertically on magazine or newspaper and take photo in dark room. The area lit up gives an indication of brightness.

There are other details to think of , first a set distance for the camera lets say 12 inch , only black non reflective paper under the light .

The camera would also need to be all at the same fix speed if one is set to a slower speed the the picture will be more exposed to light and will change the reality.
