I took it to a spare set of cases tonight. It worked rather well but I got really tired of throwing the rod down and having to snatch up the wire brush real fast, only to need to throw down the brush to snatch the rod back up. It was like a game of cat and mouse, and I was the mouse every time. Always getting chased, never chasing.
I'm sure a lot of that feeling was just impatience and impractice. Once I get the hang of it better, it'll probably go a lot faster too.
To the OP, as YFS101 suggested, you can use the alumiweld brazing rods on the case. It's a strong bond (stronger I would say than putties and epoxies) and not as costly as Tig welding (unless you know someone who will do it for free). You will still have to split your cases, but it can be done at home with a fairly simple torch setup.
On a side note, if you don't have a oxy-fuel torch, one can be had fairly cheap. It won't last long but the setup cost is significantly lower than a true oxy-fuel torch outfit.

$68 on amazon for a Mapp oxy micro torch kit. The mapp will last a long time in that outfit, the oxygen will not. About 15 minutes of good strong heat and then the flame will begin to go (slowly at first and then quickly as the oxy pressure bleeds off) to a carburizing flame.
A new bottle of oxygen, however, is fairly cheap. I was buying them (way back when) at the hardware store for about $8.
