Crank tinkering - polishing project
Moderator: robbosmans
Started out looking like this (not actual picture, but it was an anodized black Shimano spider).
Then stripped the finish with oven cleaner, tons of hand sanding up to 1k grit, then a lot of machine and hand polishing. Painted the back of spider/arms with rattlecan finish and baked in oven for a little bit. The color changed from metallic silver to a light metallic gold, which is growing on me.
For the weight-inclined, it's 789 grams. Not a tank, but reasonable for its intended use.

Those are super clean looking, kind of retro. Everything currently seems to be black
Let's finish the ride with a 20% grade.

great job
I didn't go as far on my Shimano CX, leaving it raw. It doesn't look anywhere as pro as yours but suits me because I like a low Q factor moving my shoes in as close as poss to the cranks so I tend to rub on the crank arms.

Less is more.
i'm not either, but i have zero desire to re-do it. maybe in a few years i'll get back to it....
what happened was i painted it "titanium silver" (rustoleum) and it looked terrific. then i had it in the oven just a tad too long and it turned light gold. looks more gold in photo than in person, but it's still noticeable. oh well.

How many hours did you spend on the sanding and polishing? I've never been able to get through polishing project.
Looks great!
