I've never brazed aluminum before. I bought ten feet of 1" aluminum angle and made a 20"X30" bracket to hold 4" deep filters for my HVAC return. Just a Mapp gas torch, a vise, aluminum brazing rods, and freshly brushed aluminum. I finished sealing it today with some silicone (after firring-up the box) and will install a new 4" filter, after all of the silicone dries, tomorrow.
