I'm not quite done with it at this point but I need to add a third standoff for drilling the final size. I had trouble finding anyone to convert my 9 inch axles to a 5X5 lug pattern. I decided I would make my own jig to do it therefore this is what I came up with. It's the center of a brake rotor (I think is from a Jeep) that I took some 80 grit sand paper to in order to enlarge the center hole. This lets it fit on the hub of the 9" axle shaft. I then took a wheel stud and bored a hole in it with the lathe, turned it down a bit so that everything was centered where it went in the hole and welded it in. I then made a 9/16 spacer and welded it on as well. I still need to make one for the final size so I can use 5/8 wheel studs. After that I'm going to use these with LTD-II drums, mount some hubcentric rings and call it done. Will it work? Only time will tell.
If you don't have to sweat the axle retainer hole (e.g. doing this on an 8.8) I would probably just make new holes between the old ones. In my case I had to weld up the existing holes and then drill new ones.
I would consider cobalt bits a requirement. Axle steel is tough as is the welding I did to fill the holes on these.

This is very interesting. Just wondering though why it was necessary to weld up the old holes? This is a very GOOD idea. I will see about duplicating this same jig for mine. I never thought about using an old rotor or brake drum for a fixture but it appears to work very well. Great Job!

The reason I had to weld holes is that the 9" has a hole in the hub for unbolting the retainers of the axle shaft. In doing such, it means that the bolt holes are too close to each other to just drill out. If it was 4.75" or 4.5" I may have been able to cheat welding the holes. If I had an axle that was originally C-clip style (thinking 8.8", 8.5", 7.5" etc. I'd have just put the new set between the old ones.
