Anyone on here who’s done this, how long does the finish last?, I’m assuming that alu will oxidise and this dull down pretty sharpish. Only one way to find out.

SLX Crank by nobeerinthefridge, on Flickr

I took this old goosed SLX crank into work and commandeered a grit blaster to strip the coating, which really dulls the alu, then a glass peen unit to give a bit of shine. Looks not bad I reckon, we’ll see how it last though.

I’m waiting on Cynic-al to send me a frame for welding, I’m guessing there may be some components included in the box now too….

I did a Deore one with wet n dry paper and finished it on a buffy wheel mounted in a drill with some Megiuars Metal Polish.
Came up real nice, it does dull fairly quick but it doesn’t take much to get the shine back .

Project is on the back burner (AKA cannot be arsed)

I bead blasted some stuff back in the day. Bar dirt or polishing from rubbing, the appearance did not change

Nae probs, whenever.
