bead blaster/ Cheetah / bead seater / bead bazooka?

So I had trouble with a tire, and after some Googling, I found

Murphy's soap. No thank you very much

Using a bike inner tube. Tends to shorten the already questionable life of a tube

Ether. Fire's 'n I don't get along, besides, lots of videos indicate this is...........well...

so I come to the air tank/ bead blaster / Cheetah thing. And I already have a 50 lb R12 tank converted to an air tank, so I welded a 1 1/4" pipe nipple in, reduced to a 1" ball valve and a flattened-on-the-end 1 ft piece of pipe.

I can NOT get this thing to work

Experiences? thoughts?

I'm headed back out to try some different "stuff."
