I think the main issue behind my overheating, is because I have to braze outside in a "wind funnel" of a driveway, and most of the time I have the wind quickly cooling the piece while i am trying to work with it-but hopefully someday I will reach your skill level, lol. I remember about 6months ago I was pulling my hair out trying to make a sheetmetal cod plate; now I'm brazeing gauntlets together
I suppose I will be looking back on these gauntlets in about a year and be like "Ew....just look at the warping in these pics.....FAAAAIL" and nowadays I say that looking at my mk.3 gauntlets
And for the flux removal: since I'm useing stainless, I dunk them in water and slather them with a wet rag a bit while useing the wire brush-it succsesfuly disolves the flux and teh wirebrush easily removes the baked-on flux
It's a learnign process for me, but someday...maybe soon, maybe not, I may even be casting my gauntlets out of aluminum or magnesium or copper or something
Ever think of casting yourself some gauntlets someday Mand'alor?
