[TheForge] okay how do the brits measure orifice size?

[terry l. ridder]

hello;

i have looked at the swan forge site.

how do the brits measure orifice/jet size?

according to the swan site a jet of 60 is smaller than a jet of 85.

natural air forge uses a jet of 60
a blown forge uses a jet of 85
which according to the write up on the flame trimmer uses a larger jet
than the natural air forge.

i need this information to work through the math.
