Get something like a wire wheel that'll get in the crevaces and last much longer. I mean It won't get you to the point those sanding drums are, but it'll get you close. Get a high speed drill, and a chuck... to heck with the dremel.

I'm going to be polishing some stainless tips to mirror polish once I get the proper chuck attachment for my dad's lathe/drill press/table saw. already have the right compound, and the 8" wheels.

 

Dude, you have more questions I have some good knowledge on polishing... email/pm me through MCF and I'll respond tomorrow evening.

 

The wire wheel won't do what I want it to do. It will definately shine it up, but I want to smooth out the rough casting.

 

Here is what I am looking for. I obviously won't get it this nice, but you can get the idea where I want to polish out the divids and a wire wheel won't do it.

 

Don't be afraid to use round files or curved files called rifflers to get into some of the areas hard to get to. You are going to want to use some abrasive wrapped cones,cylinders,cratex wheels, or reinforced cotton mounted wheels, and white felt bobs to get into corners for the polishing. We use polishing stones where we can, but then we polish molds, not superchargers. I've found that wet/dry sand paper works excellent, where you can get to. 600 grit leaves a pretty good finish. Start with 320 or 400 grit, always wet. use a light polishing oil, WD-40, or even kerosene.
Getting it there is the tough part, but work your way there. If you can get it that good, or maybe 800 grit, use the felt bobs and some polishing compound. Lapping compound will work, also.
Here is the BIG tip: when you get looking as good as you think you can, it will still probably have a "haze" to it. Get some Happich Semichrome polish, and buff it by hand with tissue paper, and the haze will go away. That's the only way I've ever been able to get rid of the haze. This stuff works on everything. Makes a 600 paper finish look good, 800-1000 grit look super!
Try MSC first, or Congress, Artco, or Gesswein for polishing supplies.

 

I just got some hand sandpaper as I just can't dremel anymore. I ran out of reach. We will see how it goes from here.

 

Use the black stuff, wet with light oil, and wrap it around something, like a pop-sicle stick, a pencil, dowel, or we use table knifes with the ends ground down. Tape the paper on. Start with maybe 240-320 grit, then go finer. When you want to see how good it looks, try the Semichrome polish, then cry, and go back and polish some more.

 

Well I'm taking some advice on ClubGP on polishing and that is to take the supercharger apart. It is pretty straight forward, but you really need to be careful. The bolts that hold the supercharger together have a thread coating on them so it is a PITA and takes alot of power. I slightly stripped 2 of the T-40 Torx bolts and completely stripped one. Thankfully I have a Craftsman Bolt Extractor kit and that did the job nicely. I also bought a T-40 Torx 3/8" socket bit and that made life much easier but it still took more pressure to turn the bolts than the superchargers weight/pressure so it liked to move. I ended up putting it in a vice to stabalize it.

Anyway, when you take the supercharger apart either drain the oil first or as you tap the housing with a hammer (press fit) make sure you have something to drain it in. I used my cats dirty litter box. Needed to change it anyway.

Anyway, on to the new pics!!!

GenV rotor pack. The coating is still really nice.
