After i read that post this is what i built to use with my CC. Its not so much to look at but it works like a charm. I just rest my foot on it when im at the torch and i have it where i can reach it easily when im standing.
I also placed the oxygen lever just a little below the fuel lever so that by moving the pedal just a little bit it turns on just the oxygen to the outer ring. Running a little oxy thru the outer makes the inner flame really hot.
As i move my foot down the fuel comes into the outer ring and the flame gets bigger the more i push it down. At first its narrow smaller and i have total control of how big the outer flame is.
Here are a few pics.
