Yeah, I got the cherry red. I was asserting my poetic license with white as it references the original quote from Max. As you’ll note, for this discussion, I redefined dirt too because use of some less inclusive words were causing confusion.
As previously stated, when I built my retort, it started with what I thought was the best idea that was the result of months of study. Tried it, modified,tried,modified,tried,modified…then I finally got it right. I’m doing the same thing now with the charcoal gassifier. My starting point is the Gillmore Gassifier David Parrot videos. I am unable to find the specifics of it’s construction. That’s why I posted here. There is a tremendous amount of expertise within this forum, that’s why I came here. Unfortunately all that really good information is scattered throughout this haystack(more poetic license refering to needles). If I wanted to hunt elk in Montana, given the short length of season, I’d want a guide to give me an idea where to find elk. Given time I can find my own danged elk and shoot it myself, but.
Tig nozzels looked like a good solution. They are and they aren’t. They’ll take the temp, they can’t take the volume. Other “cast refractory” looks promising. Some failed, some didn’t. Why did they fail? Was the mass too small? Was the composition(specific recipe) to blame? When “cast refractory” nozzles succeeded what was their mass and composition?
Copper 1/4 inch thick and thick iron has been touted as working for nozzles of various types. In my opinion it’s best to keep construction details as simple as possible or it ain’t worth a (poetic license). To put things in perspective, the closest Walmart is 90 miles, sorry that doesn’t translate for those on another continent. I can find clay or bentonite or ash or sand. I can make waterglass from lye and kitty litter, if I have to. I can re-invent the wheel, but it seems like a waste of time. If ya never swiped an idea and improved on it ya ain’t worth a(poetic license).
