Does Anyone Here Do Neon (It's Enclosed In Glass!)?

Since LP contains roughly 2.4 times the energy per cubic foot as natural gas, the area of the orifice for natural gas would need to be 2.4 times the one for LP given the same pressure. Possibly (probably?) you won't have the same pressure, but since I have almost no experience with Natural gas, I wouldn't stake anything on that.

I'm not sure what you mean by "screen" but if it's as I'm envisioning, I think you want to open (or preferably change) the jet rather than the screen.

About the only experience I have with changing a gas orifice size is this (which doesn't really apply to your situation, but being as it's essentially the same thing as a ribbon burner, might be of interest nonetheless):

Hey Joe, did you try the manufacturer or distributor of the burner to ask them about the orfice, and that is what you want to change, not the screen. You need a larger jet, but I don't know for sure how much larger without knowing your burner. I have a friend that ran NG with his ribbon burner and I could drop him a note to find out what he uses at what pressure.

Without questions, there isn't much activity.

I've got a question, then?

Where's my long-promised DVD on making molds? ROTFLMAO

A neon ribbon burner has no jet that I am aware of. The "screen" is actually a metal plate full of small holes that, I guess, serves the purpose of multiple jets. To change a ribbon burner from LP to NG, the manufacturer just supplies a new screen. The burner head (with the screen) sits on an "economizer", which basically just shuts most of the gas off to just a pilot. The same economizer is used for both the LP and the NG versions.

See:

The type I have was made by Hyde or Voltarc (depending on age: I think they were the same thing - at any rate I have one of each and they look identical). I know there are ribbon burners of a more conventional construction, but that's not what is normally used in neon fabrication.

If you have a friend with a neon ribbon burner of this type, I'd appreciate knowing what size the holes are. The dist. did tell me that it's just a standard number drill, but he didn't remember what one. I just plan to modify one screen, and leave the other intact, in case I ever want to (have to?) go back to the expensive gas.

I'll also try the Neon John ping.

Thanks to you guys for your replies. Joe

Hey, I got the ZingBrush on You Tube didn't I? What else you want? You need to get that zingbrush web page going, for serious, I put that address up there and then went looking and got surprised!!

You don't need that DVD, you got me!

I don't see him often, I will try and get ahold of him to find out the number drill that fits.

That's a pretty crappy youtube video. Blurry and no sound. Makes me wonder if it didn't come out of Canada somewhere.

First try at it and bite me, The lady running it is small in stature and wings that thing around that window and does NOT have sore choulders from buffing the window and you should see what it does on brass cabinet door panels!! talk about glow!!

The video will be improved upon, but you get the drift...

Didn't realize you did the vid. BTW...what's the diff between the zingbruch and the Pzazz brush. Both seem to do the same thing. I've used the Pzazz for years and pretty sure I get the same result.
