Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

sandblasting deep v's...

i want to polish my silver anodized deep v's so they are shiny. i know i can use easy off oven cleaner to remove the anodization but its a dangerous substance so id rather have someone else deal with it.
if i have a shop sandblast the rims to remove the anodization, will it mess up the aluminum?

It'll probably scratch up the aluminum a good amount, but with the right grit sandpaper you can remove most of the scratches. I'd be afraid of pitting, but i suppose you can give it a shot.

Sandblasting will cause putting in the aluminum so youre better off getting them media blasted with something less abrasive.

There is no reason to do this at all.
Just have them polished or start polishing them as they are.
Anodizing is very very easy to get thru.

The fine grit sanding that you will do to start with will go thru the anodizing like its not even there.

If it's such a dangerous substance, how come housewives and maids and **** use it? Put on some rubber gloves, take it outside to a ventilated area, and harden up, dude.

And wear a dust mask if you're sanding. Aluminum dust'll give you that Oldtimer's Disease fer sure.

Don't sand blast! Just startvat like 400 grit and see how it looks. Go lower if you have to. Then work your way back up. 400 600 800 1000 1500 2000

Start wet sanding at 800. They will be blingin

i would man up but i heard oven cleaner eats away at the aluminum making it weaker

here's a trick i learned from anodizing paintball guns...you strip the anodizing by soaking the rim in Draino...

I am so glad I chose this name. I just didn't get why you wouldn't get a polished V to begin with, but it could have been a gift or good deal or whatever else. I hope it goes well and you don't muff up your wheel.

Also, don't forget to take off your rings if you wear any. Aluminum is a soft metal and polished aluminum will show scratches from being handled while wearing rings.

I know that this will be taken the wrong way, but I've learned to always take off the wedding ring when polishing my crank.

just so you know, the machining does little to help braking performance. people braked on non-machined rims for quite a while.

you're welcome (I knew that would get taken out of context). The worst part was when a friend asked me what I was working on that I needed the sandpaper, finishing grade steel wool, and rubber gloves for. Now days I just mutter "bike stuff" and wander off.

Except for that they weren't powdercoated.

Don't sandblast it. If you want to go that route, look for someone who does bead blasting or uses other forms of media like baking soda. If you can't find anyone, check with a radiator shop.
