This will be "weather Vane Sized", and inspired by Jet Fighters, such as the F-4 Phantom..but limited to my resources of snips, hammer as etc. I keep trying to find a cheap sheet roller, but they don't often show up.
This is a 6" scrap of gas vent pipe. The finished plane will have about a 30" wingspan, and be about that long...more or less...I know it takes a lot of head-scratchin' to see how it'll ever get beyond the scrap pile stage...and maybe it won't, but I've been wanting to try my newly acquired HH187 on some thin sheet, and this is about as thin as I usually get (about as think as two sheets of printer paper). The steel structure to support it on the vane, plus support the wings, will be inserted inside, the, either riveted or bolted to the main fuselage, so it should be relatively weather-proof.
I first tried my ,030 Techniweld wire, running on #1 - 25ws. The machine performed just about exactly like my HH180 did. then I switched over to a roll of ESAB .023, which seems to run hotter than the Techniweld did, and not quite as manageable as it, either...but 'ya never know if'n ya never tries!
This was my first lap joint on this thin stuff with the ESAB wire. (forgive my wanderin' line. I was impulse-ing with the trigger (my usual thin sheet approach), I was only able to "weld on the welds" without burning through...slower, but it works! The 187 had definite differences between the 120 wirespeed, 125, and 130...120 sputtered, 130 was too aggressive, 125 seemed to work best...but a tad hotter than I thought it should be.
