Welding overhead is always the hardest, because when you melt metal, it wants to run downhill, like any other liquid - so it becomes kind of a challenge to get your bead to stay where you put it. If you goof up, it wants to fall off - and being under that is a good way to get droplets of molten metal on you. Not fun.
This was mildly sketchy, but not too bad. I'd have loved a real rotisserie, but this worked pretty well.
And, let's face it, it's going to be only a few inches off the ground when all is said and done, so I doubt anyone will ever look at it again.
And thus my goal is met to drop the tail end of the transmission by about three inches. This should mean a much longer life.
