--OK here's the thing: I'm trying to push a good flow of propane

a wee pressure regulator attached to the widget (threaded 1/4" pipe but I
could go up to 3/8") but it's definitely acting as a flow restrictor, not
just a pressure regulator. Is there a device that can solve the problem?

The average individual appliance regulator has a needle valve oriface
that's very small. You won't get any appreciable flow through it.

Most gas regulators won't tune up to 10psi, either. I don't remember,
but think it was in the low tens of inches of water column.

Our professional flame effects use gas _rated_ high-flow regulators with
1/2" piping. I'd think a very large welding gas regulator might suit the
purpose.

A cheaper and more readily available regulator would be one for a high
BTU/Hr "jet" burner outdoor cooker. I have one that is rated at 105,000
BTU/Hr which has an adjustable regulator that goes from 0-10 PSI. The
whole unit was $60 at a local sporting goods store.

I use one that looks like the model with the small black knob shown here

http://www2.emersonprocess.com/en-US...Pages/67C.aspx

It's good to 300 or 400 thousand BTU. I payed about $50 for mine from the
local propane dealer. Mine goes into the tens of PSI. The place I got it
from made sure to get me the connector for the propane tank that didnt
have a pinhole drilled though it, like with a grill- it's like a piece of
pipe- there's no sort of flow restriction at all with my setup.

If you're willing to make something yourself, you
might look at the design of a hot air balloon
burner.

Fisher (I think) makes propane regs that are adjustable up to either 30 or
60 psi . I have the 60 psi version on my foundry burner , but have yet to go
over 30 . I think I'm pumping around 80,000 BTU's thru it when it's at 30
psi (.030" orifice/1" Mikey burner), all I know is it'll take 10 lbs of
aluminum from ambient (cold furnace) to molten in under 20 minutes .

I suggest he searches on Mike Porter and/or Ron Reil burners . Opens the
door to dozens of pages of info and designs . www.abana.org has links to a
lot of burner info- all within the capabilities of most home shop types .

I have a high flow adjustable regulator from Tejas Smokers that goes upto
20PSI. I run my big grill at pretty low pressure, but the higher flow rate
makes it burn like it should. Buy it and the green acme high flow inlet
fitting (unless you need the red one).

You need a larger regulator.(not higher pressure)
