Ok as long as the peanut gallery is getting warmed up here, here's one. Tonight's project was adding 2 light tabs to a bike rack, for use either as tie downs for the bikes, or more likely straps to the bumper, to reduce side-to-side action.
Both materials are about .100" thick, which makes it easier. I struggle when I'm trying to stick a .250" plate to a .065" tube... keep blasting through the tube. But tonight's only real difficulty was I couldn't get an arc started until I sanded off the paint below both the clamp and near where I wanted to weld. I'm usually attaching stuff to things that have already been painted so I'm used to this.. ended up cranking up the welder a little more to get it going, and in hindsight probably could have backed off another 25 amps or so, since I had to go really fast.
