How to clean up the aluminum cases

"Sisal" wheel...that's the rope filled one, right?
It can be yes. I'ts more specifically a type of fiber. The most important part of this though is the black compound. it is very abrasive as compared to other compounds such white green and brown. So long as you have a stiffer type wheel you should get similar results though it may take longer. People do seem to prefer the sisal wheels.
 
It's 6 of one, 1/2 dozen of the other when it comes to stitched cotton vs sisal. Obviously both Ed and Steve have achieved great results with their own methods. It may benefit the OP to contact Steve and ask his prices for polishing. He quoted me some caps & bowls a while back and the price, well lets just say you can't afford to do it yourself for how little Steve charges. The project did not warrant me doing it this time but I will use Steve in the future. Oh, and hello Steve, looks like your back!
 
Wow, a lot duller than I expected...thanks for the pic! ....Btw, what pressure where you using...the only sand blasting I ever did was black beauty @ 80psi to remove rust, so my experience is limited.
I have tried glass bead, aluminum oxide and walnut shells, all at about 90psi. The walnut shells didn't do anything except waste some time (OK, a LOT of time), the other two looked pretty much like shibby's picture.

Yep, I'm back. :oops:

So again, which wheel depends on how much scratching and/or corrosion you need to remove. The Sisal wheel is stiffer and will remove the imperfections and sandpaper scratches easier. It doesn't buff the surface to as bright a sheen though.

I tried to used walnut shells eons ago to clean up an engine{car} for painting....ugh...took forever. Swapped out for the good stuff....much better results!

I've got harbor freights loose and sewn wheels, with green rouge, for a brass clean up project at work....nice results. They had a rope centered wheel....just never got it. I don't remember them having black rouge...will have to search around for that....probably eastwood....

Sears sells the black cutting compound. I didn't see a sisal wheel there though.
 
This thread is timed perfect for me. I've got my engine in pieces and was researching what to do to clean it up before putting everything back together. wahoo!

Yes, that is true. Your work is very nice.

I have done just a very little bit of buffing. Two recommendations: eye protection and welding gloves
 
The way you hold the pieces is very important. You can do yourself a serious mischief. A stout apron is also advised.

Adding something behind the wheel{s} isn't a bad idea either....there's all sorts of "stuff" on the side of my toolbox at work from using the polishing wheel a little over a foot away from the back of it.

And yes, a good grip and angle of attack is very important when polishing....

Thanks, I'll check there for the color.
Did you start, usually, with a sisal wheel...then finish up with either a lighter sewn wheel or a loose unsewn wheel? {and lessor grit rouge of course}....curious.
 
That starter cover doesn't count Steve!
;)
So you have no problem with the cam chain tensioner or the oil pressure sensor?

How about a breather cover?

Cam retainers?

Oil cooler manifolds?

Sorry, but if it's there, it deserves to shine. :encouragement:

I was just making a joke that the starter cover is already chrome. Of course all those other bits look great. I've seen your work before. Thumbs up.

No, I don't use any other wheel. The sisal w/cutting compound brightens the aluminum more than enough for my tastes. It's actually brighter than that of the OEM Suzuki finish.

Good to know....Thanks, will try it your way.
