Thanks for the prompt replies already everyone. Much appreciated.
Added my location into my profile, im waaaay down in the south pacific - New Zealand. Close to the forges of Middle Earth.
George N MI run on a 9kg propane bottle with a high pressure regulator (up to 30psi). I did read somewhere, rightly or wrongly, the inline pressure gauges are a bit hit and miss. I do like the idea of figuring out what its all running at, even if its not hugely accurate - better than guessing i suppose!
Frosty I built off these here.
Artisan Supplies Gas Forge Dual Large Burner Set with Hose and Regulator 130mj/hr
I couldn't justify spending up $600NZD for them. I got in contact with them and queried a few specs with them a while back and built off that. Based on my naivety, I though getting all the inlet/fuel lines another 4" (8" to 12") away from the hot area, things would be better at keeping things cooler.
I do admit, I had some 0.03" tips lying around my shed and was too lazy/cheap to get something larger at the time I put my burners together. My rationale is that I could get everything working and fine tune things after. Ill pick up some 0.04" tips next week and swap em out.
Getting parts like steel barrel nipples can be bloody tricky in NZ, I think I actually had to go to Australia to find some long barrel nipples. I'll see if i can track down some shorter 8" barrels.
Irondragon Cool nice to hear. I'm still very cautious when firing up something really hot with propane, so do check all my joints with soapy water before each ignition. One day I'll get a little more comfortable working with hot things...but not too comfortable.
