Mikey98118 Posted May 6, 2019 Share Posted May 6, 2019 Well, you aren't going to get much farther without doing a little research on flame retention nozzles. Look up Mikey burners on the Web, or read through the Burners 101 thread. Quote Link to comment Share on other sites More sharing options...

Mike means a sheet metal nozzle WON'T last long. It will burn up very fast. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
G-son Posted May 16, 2019 Author Share Posted May 16, 2019 New nozzle (still sheet metal for testing), about 1mm larger diameter and 2½* mix tube i.d. long (as suggested by Mikey in an earlier discussion). The improvised firebrick "forge" appears a bit brighter/hotter in the video than it actually was, but the video was taken a couple of minutes after lighting it. Gas supply won't let it run at max for more than a few minutes, still stuck with the small canisters. In open air, outdoors, on a somewhat windy day, the flame is hot enough to melt brass and turn steel bright orange. Heated & quenched a piece of spring steel, it hardened.

Mikey98118 Posted May 16, 2019 Share Posted May 16, 2019 Congratulations on making a very hot flame with your very first try. You will need #316 stainless steel. or frefractory for a flame retention nozzle. On the bright side, lots don't need a nozzle in forges.

G-son Posted May 22, 2019 Author Share Posted May 22, 2019 Trial by fire, the only way to test a burner. First real use of the burner was heat treating a new jaw for my old broken sheet metal shears, made it from a worn out file. Might still want to grind the jaw to a slightly different shape, but all in all, worked out great. Edit to resize huge photos. Quote Link to comment Share on other sites More sharing options...

Jungle: I wince every time I see your supply tube sticking so darned far out of the burner! I understand you need enough to adjust but in the last pic you could advance the jet through the burner and part way across the forge! -Frosty I blush anytime I get a response from the Elder Curmudgeons.

G-son Posted May 29, 2019 Author Share Posted May 29, 2019 "I measured once, cut twice, and the XXXXXX thing is still too short!" Prototypes get extra length where practical, much easier to cut off excess later than adding more if it's too short. Quote Link to comment Share on other sites More sharing options...
