I originally started using this for my aluminum motorcycle parts but when my boss saw a 3.2 intake he asked me to send out some pieces from the shop. We just got back two 67S sand cast aluminum cases. They aren't painted but they almost look that way. The vapor blast is a pressurized wet mixture of micro glass bead, water and soap. Done in a big tank. It polishes the metal vs leaving a rough finish like regular glass bead. It's also safe for internal engine areas. No residue. The guy I send the parts to is $60/hour and the exterior of the engine case took 2.5 hours. Intakes were 1 hour for the pair. My 40 year old motorcycle parts look like new. (Except for bigger scratches).

Those turned out really nice! Do you have to contend with the oil passage ways or do they squirt the media thru those too?

We asked him just to do the outside of the case because ours was just for cosmetics but on my motorcycle case I had him do inside and out. It leaves the inside looking like new without any residue. He also uses a sonic cleaner so all the passages are cleaned. There are a couple people around the country but after checking them out I settled on this guy - http://noreasterblastworx.com His name is also Mark and he's in New Hampshire. He's been very easy to work with. If you do decide to contact him, he often takes a day or two to return the message. |

Looks like a good answer for our aluminum fan shrouds too - in order to not get a polished look to them, in addition to engine & transaxle cases, etc.

Parts look great....I don't like the name! Not a vapor process (IMG:style_emoticons/default/smile.gif)

Here's some of the drum brake parts I sent and one before photo.
I started researching this because the aluminum parts on my bike were heavily oxidized but the fins on the engine case and hubs made palishing very difficult. Traditional bead blasting didn't have the finish I wanted. The vapor blasting did. The Porsche aluminum turned out much brighter silver than the Italian motorcycle parts. Attached image(s) |

I just started working on my second motorcycle rebuild. This time, instead of sending out the parts for vapor blasting, I can do it “in house”.
First step is cleaning. The shop ultrasonic cleaner is big enough for a Porsche engine so my little 350 was easy. Attached image(s) |

The vapor blast machine was just serviced so 5 minutes on each piece was enough to make it pretty again. (IMG:style_emoticons/default/smile.gif)

That's awesome! The before looks just like my carb bodies. Going to try to tear down and clean the second carb tomorrow. I need something to get my mind off the brake caliper fiasco (IMG:style_emoticons/default/biggrin.gif) |

I'm in the aerospace precision cleaning business and we never ultrasonic aluminum. What you see on the surface of the aluminum are cavitation marks generated by small implosions that are super hot in excess of 300F on the aluminum when the ultrasonics are on. Excessive exposure to sonication can generate pits and even cracks on the surface of the aluminum. When cleaning aluminum and ultrasonic cleaning is desired, its best to only do small burst 15-20 seconds of sonication at a time but not to exceed more that a few minutes in total for the cleaning. |
