1/4 inch 20 pitch (camera mount) to speaker stand (35mm) converter

I have a Alpha Antenna Mag Loop which I want to put on a speaker tripod (rated to 100 pounds). I remixed a microphone converter to instead work on speaker stand's 35mm round peg. The peg on my Amazon generic tripod is just under 35mm (calipers say 33'ish) and about 45mm tall. For a Mag Loop this tripod is massive overkill, except I guess in windy places you'll appreciate the stability.
