    Default Totally polished carbs, intake, balance tube, and chrome heat shield

    Finally finished my "show carbs", I think I'll throw them up on "pay it forward"?

    Seriously, they look so nice, I'm thinking about putting studs in the wall of my office and hanging the up like art.

    I don't recommend that anyone else do this... It took forever.

    Very impressive. The chrome heat shield is a nice touch!

    Nice job indeed, you should have shaved your balance tube and made a euro style.

    They look hideous, I will be more than happy to take them off your hands and hide them under my hood!

    How did you go about doing it? By hand or with a buffer and dremel?

    Actually all of the above. but I started with sand paper of higher and higher grits... Up to about 1200... It's not a pleasant process.

    I agree with the above that I should have used a euro-balance tube. Maybe I will sell this one on ebay and get one of those (I'm not going to start shaving/repolishing this one). Fortunately, that's the easiest item to polish.

    Here is a slightly different angle. They really are so nice to look at that I'm seriously considering just bolting them to the wall of my office and naming them "Art".

    Put it in your office break room kitchen. People will think it's a new expresso machine

    That setup looks amazing....My intake wasn't polished and now that I see yours, I wish it was....

    have a look at mine and then you will see how awesome it will look under your hood. I had the cad plated fuel rail and polished valve cover as well for the bling factor.

    beautiful job....

    You have a beautiful engine bay, I like to think that if I actually install them, they will have a nice home as well (see attached).

    Very well done....mine was no where near that clean. I was going to try my intake this winter and wanted to know....how long did it take to get it smooth with the different grits of sandpaper? I've done wheels and I know it's a PITA so I'm thinking it's probably more tedious than labor intensive?
    Also...were you wet-sanding?

    thanks for the insight and congratulations again...

    I actually started with a wire wheel connected to my drill, that did a pretty good job of getting it started, then moved to 180 grit wet sandpaper, and just started working my way up.

    i used a dremel to get into the difficult places.

    One trick I found is when using a specific grit, always go in the same direction. Then when switching to the next higher grit, sand at 90 degrees. This way you always know that you have removed the scratches from the previous grit.

    When you're done (at about 1200 grit), switch to rouge and a buffing wheel on your drill.

    Then, finally, I followed that up with Mother's aluminum polish. Calling it a PITA is an understatement. I spent a couple of hours per night for about a week on each manifold. I attached a pic of one manifold midstream and the other waiting in line. FYI, this project took a solid couple of months on and off.

    Wear gloves or you will have permanently grey fingers, and your fingerprints will be gone.

    One more thing, the polished carbs are a backup set, not the ones in the engine bay picture (those are my daily driver carbs). I bought the polished carbs on ebay with the manifold for about $50, gives you an idea of the condition....

    You really need this kit.... http://www.eastwood.com/buffing/meta...-ew-motor.html

    Awesome price, great buffing motor, comes with a full kit including (6 compounds, 8 buffing wheels, face sheild, How-to-DVD, gloves, and a wheel rake.)

    I have something similar (bits and peices over a period of time) but when I get the money, I'm all over that kit.

    Here's some before and afters. The valve cover (from painted to stripped, to sanded to completely buffed in only 8 hours. Same with the front cover and oil pump. It's addicting and you'll find yourself buffing everything.
    Check my gallory (page 5 and 6 ) for my carb polishing
    Awesome work though, I did the same with my SU's and love 'em. They'll look right at home in your very clean engine bay.

    Wow, you do some nice work, and that kit from Eastwood looks great. I get "daily deals" from Eastwood, and occasionally they send "20% off on orders over $75 plus free shipping". I think the next time that deal shows up in my email, I'll jump on it.

    I agree, the results can be addicting.

    Thanks you. And keep in mind that the small parts were done with a 1/2 HP bench grinder with 6" buff pads. And the valve cover and some of the front cover were done with the same 6" buffs on a 4" hand grinder. But you have to keep constant contact to keep the RPM's down.

    I wanna grab anothe Unilite and polish it as well. We'll see.

    The setup looks great. Reminds me of the Christmas season that I polished my balance tube and intake in the living room.

    You guys do outstanding work!! They look great! What do you do to the finish once it is polished? Do you coat it with anything? I have wire brushed my manifold and it is now "brushed aluminum" and was wondering if ther is anything out there to help keep it looking nice.

    I like to use Easwoods Extreme diamond clear. Hi temp and pretty good at chemical resistance. Which makes it great for the engine compartment.

    I havent done anything to the finish yet. I just keep it clean with windex or any streakfree cleaner. I will probably look into the Eastwood product.

    Good vid on polishing.

    I would love to get Z's and 260zCaliCar's opinion on the technique. I like the sanding buff this guy uses instead of hand sanding for instance.

    I love the greaseless sanding compounds from eastwood. Great for cut-in and definantly quicker than hand sanding. I use everything at my disposal, Sandpaper and a block, DA with aluminum oxide sanding paper, wet-sanding and the easiest for me is a 6" sisal (spiral sewn with sewn in rope or something) it's very strong and used for steel and Stainless) I use that with red or black compound for my cut-in to remove casting marks and heavy lines.

    Then I switch to a standard spiral sew with red compound then swith to white. Then I go to a loose cotton with white then use only the loose buff for a final polish. Then I wash it in warm water with Dawn dish soap to remove all traces of compound. And then I can tell if I need to rebuff anything on the part.

    His technique Is the right way. Breaking down the surface levels till you get to the solid, buffable surface. It's very time consuming so don't get into it unless you're in for the long haul.

    If it's aluminum, and it's on my Z, it's probably polished.
