Okay so at your advice I looked over my welds closely and decided I will rework them. Here is a video to get a closer 360 view of each. I noticed the first inch or so of each weld is cold and then starts to wet out more. The cold parts of the welds and questionable overlaps at the ends are what motivated me to rework.

In retrospect I think I would have had better results if I preheated the housing, but even so I think the starts and stops and time to re-position the housing between welds were the main contributing factors to the result. So I decided to enlist my kids to help me make a rotisserie. Here's what we came up with:











The rotisserie we came up with is a simple set of stands made from 4x6 and 3/4 plywood remnants with opposing chair casters on top. Fixed wheels might work better, but I had these on hand. I'm hopeful they are far enough from welding heat that they won't melt. I bolted a pair of heavy steel lift/lowering blocks to the diff cover to balance it and formed a crank handle from a piece of scrap aluminum. Here's a video of it in action.

I'm happy with how it works; it rotates smoothly and feels balanced enough that I can stop at any position and the axle housing doesn't try to swing around on me. My plan is to crank the housing around with my left hand while I weld with my right (I'm right-handed). I'll try to position an arm rest to keep my welding hand steady. I thought about trying to power it with a drill or something to get a consistent feed rate, but I'm not sure if I could adjust the speed quickly enough whereas with a hand crank I can adjust as I go. What do you think?

I ground out the old welds with a 4-1/2 grinder. Here is what they look like. There is a bit of a radius inside the corner due to how the grinding wheel wore on edge. Should I get a fresh wheel and try to reduce that radius to form more of a sharp inside corner before welding?

Nice simple fixture. Could you rig up something with a belt and your drill to power it while you weld???

All that is needed to automate the rotation is a bit of rope:
Tape it to the axle tube and then wind the tube the opposite direction from the rotation you want about 8 or so times, then put a loop in the free end that you can get yer foot into and step down the tube will rotate and you have the control of it in your foot.
You could also attach the rope to a 1x2 (or) and set one end on the floor while the other is the distance that = to the Dia of the tube so that stepping down on the stick rotates the housing one full rev.
Now you have one hand running the MIG one foot running the rope turner.
Can you chew gum

I am not nearly coordinated enough for that! If I'm going to automate it I need to find something with a dial-set speed like the table feed on a mill.

My take is the hand control and a fixture to hold the mig gun will be the best.

If you don't have allot of weld positioner experience it's going to be allot of work for nothing to power it. I used my mill rotary table one time with a vs drill and it was pretty hard to control.

Got a buddy that welds?
If so she/he can watch what you are doing and spin the tube as necessary.

Edit:
Without the welder, you really should try the rope on a stick, you may be surprised at the ease of it and it wont cost much if anything to try

Are you suggesting to fix the mig gun in place? I was thinking a rest so I can still weave the gun back and forth between the housing and the housing end.

Yeh my bad glad you asked. A rest for the gooseneck would be awesome, let you focus on the axle spinning.

Yes. Where do think they find all these "you're not a welder when" photos?
