Cook Bros Crank Restoration

[midibiker]

Oh, and short dips in caustic soda, followed by cold water dips, and repeat, does a really good job at removing anodizing.

Yes but not as good as bleach.

I have a good collection of cranks. Cook Bros / Grafton.

Here’s a before and after of a pair I have (credit for the polishing is not mine). The before image doesn’t do justice to how bad they were

That's a good transformation.

They can come up good with a bit of TLC.

My Topline/Gratfon ones have not come out as good as I would have liked. But I'm going to have another go at polishing them with cleaner materials this time.

If that doesn't work I will spray them in black, apply the Topline decals and clear coat them.
