LOL Well I cleaned off one spot and now I am going to ended up polishings the compressor housing.



Started off with 60 grit to grind down the letters. Now going hit 150, 320, 600, 1000, 1500, 2000

 

Hmmmmm....

 

Here's a bit of advice...

Pick the most inaccessible, hardest to reach spot and start there.
Then move to the easy sections and bring them to the same level of finish.

Overall a part (any part) looks better and more professionally done with a consistent finish- even if it's not totally shiny- rather than having highlights and then areas where it obvious you couldn't get into.

 

what tool do you recommend to get into the small spots? a dremel with sanding disk?

 

A Dremel doesn't have the guts to do a good job.
You'd need a heavier duty air tool and a variety of bits (lots of cones I'd guess, looking at the housing)...essentially a very similar setup to what portwork would require.

And I hate Dremels, so there's that.

 

lol sounds like a job for die grinder

 

Yeah.

 

Careful withe the die grinder... You'll find that it won't take much contact to **** up the housing.

 

Well I picked up a Makita GD0600 die grinder 1/4". Can you recommend some stones to use to sand with? are there any polisher attachments?

 

This may seem redundant... but you realize that in addition to the sanding part, there's an additional polishing step right?

 

yes I have polished intercoolers and pipes before. I just have not polished anything thing with small small hard to reach areas. I have never used a die grinder with stones before to sand down the parts. Once I get the hang of it I wanna polish up some rotor housesings and a front cover

normally I start out with around 80 ~ 120 grit depending how the surface is and if there is anything I need to sand down. like a seam from the casting. I used 60 grit on this to get the letters and casting marks down fast.

then I goto
150
240
320
400
600 wet
800 wet
1000 wet
1500 wet
2000 wet

After that I use white rouge on a polishing wheel
then Mothers Blue put on by hand and polished off with wheel Let me see if I can dig up some of my pics
