When you send a carburetor off to be rebuilt,it comes back nice & shiney.How do they get the whole carb to look so good.
There was a newb that posted spam...as for the question, don't they just dip it in a hot tank or something?
Most of the time the components are placed in one of those vibrating deburing machines. It's a machine that has a tub filled with abrasive media (it varies depending on what you want to accomplish) and the tub is hooked to a motor that has an eccectric attached to make it vibrate. The part and the media slowly cycle in the tub creating the shine on the part. When it comes out it has that polished look. The less agressive the media the higher the shine. Frank
I was at a friends shop who had a pollisher like that, he said his was made for pollishing shell casings, for reloads. He used it for pollishing parts, nuts, bolts, ect. Said its alot cheaper than the ones marketed to automotive restorers, same thing, different use.
The term that I know is "britedip". I have the formula. Its a truely nasty concoction with sulfuric acid,arsonic and some other yummy chemicals. Not for home use and potentially leathal. Oldmics
I plug off all important holes etc and use a parts tumbler/cleaner. You gotta be careful cuz it will remove sealing ridges. Sometimes I'll put the whole carb in ***embled.
