Matt Vandart Posted January 31, 2012 Report Share Posted January 31, 2012 Sand blasting will make the frame more prone to cracking. It can and will introduce the dreaded stress risers. People get shot peening and sand blasting mixed up. do what you want though dude, I'm just letting you know. Quote Link to comment Share on other sites More sharing options...
Skoze Posted January 31, 2012 Report Share Posted January 31, 2012 Whatever you do make sure you go and see what they're actually gonna be firing at your frame, the shot blasting gear at my dad's old place was f**king brutal - i'd never even consider putting my bike in front of it!

Luke Rainbird Posted January 31, 2012 Report Share Posted January 31, 2012 Depends hugely on the media/pressures used as to whether it's going to give any real-world issues. When I was working over at PTC I did a few sets of forks (couldn't do frames as the cabinet wasn't big enough) and being as the media was small and soft it took a fair while to strip through, certainly nothing too harsh. If the setup your guys are using is similar then you'll have no issues with the frame at all, but probably worth checking out anyway just so you know what's going down Quote Link to comment Share on other sites More sharing options...
dezmtber Posted January 31, 2012 Report Share Posted January 31, 2012 just spray loads of silicon spray on the alloy once every so often it keeps most corrosion away Quote Link to comment Share on other sites More sharing options...
dann2707 Posted January 31, 2012 Report Share Posted January 31, 2012 My mate got his onza comp acid dipped and it removed all the paint. Could you do the same? He rode it for a year pretty hard (if anyone knows neil they know he doesn't mess about when it comes to landing hard ) Looked so nice too, infact I'm thinking of doing the same to my frame asap as he can get it done for me super cheap.

dave33 Posted February 2, 2012 Report Share Posted February 2, 2012 Define pure? and it will oxidize, but it's not a problem Bit of lacquer will sort that. Water wont make too much difference as ally oxides in atmosphere (ie, oxygen) . Wouldn't agree with that, have shot blasted a few frames myself, left the threads uncovered (all of them), never had a problem. It's very much to do with which blasting media he uses (garnet, aluminium, bead, ect). Ask him if he can use a softer media (possibly ally oxide or a small bead, might take him longer, but will stop anything happening to the frame), will be fine then . i would agree with rob on here, just depends who does it and if they are used working with ally or not, there is a shot blaster where i work which tears off steel. probly best to ask a few questions to see what type of stuff they do.
