Polishing 250-2v intake?

[michael_cini]

my machinist had my intake sand blasted (yeah, it was quite grimy) along with the cylinder head. now it is a bit rough. how do i go about polishing it. i don't want it highly polished, just back to a stock, clean semi-polished look. thanks.

btw, ignore the red circles on the pic, that was for a different topic!

Sand paper, lots and lots of sandpaper.

Seriously, either by hand or with a drill or some sort of automatic sander, you start off with a course grit and work your way down to fine. At that point, you can actually buff it with a wheel and make it look like chrome.

a cloth wheel on a grinder.(be careful on the speed) you can pick them up at home depot. I bought a variable speed bench top polisher from grainger. I just use a flapper sanding wheel on a drill to take down the casting bumps and ridges.

you could get these:

then there's the rouge, black first then red .finish it off with white.

if you have a harbor freight by you , you can get this stuff there.

Can you get it wet blasted? That gives a semi-polished, new look.

You can also take it to one of the ceramic coating shops, that use a wet bead tumblar it comes out smooth and polished with out all the work of hand polishing. I have has mine tumbled in the same state as yours is and they have turned out great. Should cost $20.00-40.00, they just drop it in and set the timer

thanks for the info guys. i had spoke with ben (mustangaroo) before about this, i would prefer to go this route. and i think his intake and valve cover look awesome! however all of the polishing/coating/chroming places i researched and called in my area none of them did tumbling. how do i find a place to do this for me?

Look for a real custom bike builder and restorer. They'll know somebody.

as a test,you could try to spray the underside with ceramic silver exhaust coating. it might smooth it out abit and get the look your wanting.

or....a soft wirewheel on a drill and then use a dremel for the tight spots.
the wirewheel will clean it up without over polishing it.
