Polishing a supercharger/blower

[4Lance]

I want to get a kit to polish Aluminum parts on my F150 Lightning. The biggest peice i want to do is my supercharger. It has alot of small spaces to get into. I've done other little engine parts off my truck already. just want to do the blower now. here is a website that does them and what the sc looks like. I see 2 kits caswell offers on ebay. one has alot more than the other, but one has White Rouge Liquid Polish, i will be using air die grinder,dremel, and elec. drill or drill press. I dont have a bench buffer yet. What would a place like stiegemeier use to do these blowers?? I'm think about starting a shop doing this. Thanks


Can someone please take some time to tell me everything i need to do and how to do it correctly to get a show shine.

There is a coating on it now from the factory. what would you use to strip it off first??

I also have a alum. pulley with a black coating? how would i remove it?? i think its black powder coating, so i can polish the pulley. thanks sorry for all the questions.

for the pulley if it's PC, then aircraft stripper will take that off. if it is anodized, easy-off oven cleaner will work. same for the blower itself, if it's a clear paint, stripper. if it's anodized, easy-off.

as far as polishing it, i'd use some sort of flexible shaft grinder. i got a cheap one i got off ebay that came from harbor freight originally and it's great for me. probably not the thing for making a living off of, but i do it because i like it. if you've got a regular bench grinder, you can use it instead of a real buffer. caswell sells a thin razor buff that is GREAT for getting between fins like are on that blower. not sure of how much space is between those fins, but a regular sewn wheel might fit in there too. go ahead and get the treated wheels, it's worth the money for those. if the original finish has alot of pitting from the casting, you'll want to use greaseless compounds to cut out the hand sanding.

here is a couple pictures what the sc looks like polished?? i'm just worried about how to sand all the tight spots, do you use soft wheels with the greasless compund or sanding bits?

That SC was more than likely polished in a vibrator. Read all the stickies at the top on the page and then ask your questions. I'm not trying to be flip but a SC is a big undertaking with a lot of labor involver. Personally I'd start with greaseless, or cartridge rolls.

Holy cr*p, look what they get to polish that thing! My work's as good as that...I need to review my pricing. I could never turn it around in two weeks, though (until I go full time).

Anybody know how these things start out? Are they cast or smooth to start with?

I'm still doubtful about the vibratory tub taking aluminum from cast to polished - especially since I haven't found anybody who's actually done it.

mpierich,

The reason I suggested that it was polished by a vibrator, was that the gasket surfaces are polished. Not something you would do when you hand polish, at least something I wouldn't do.

Oh, I'm not doubting it _could_ have been done that way...just that I've never had anybody tell they've actually done it that way. As for the gasket surfaces, some people probably clean them up when they polish - I don't. Just thinking about it...if I were going to use vibratory that way, I would certainly plate off any gasket surfaces and openings so I didn't risk messing up the flat surface. You can only do so much with Permatex...

Speaking of superfluous polishing, I've seen people do stainless brake rotors and they do a show polish on the braking surface while they're at it. Pretty, but totally unecessary and possibly dangerous.

Here's a different s/c but the casting is about the same rough!

Thanks. That's a very nice casting actually - would take a lot less grinding than the manifolds etc. that I get to polish.
