Hi MAPRIK, first of all let me tell you that your cryo looks awesome, no kidding! I just wish I found this post earlier... I have a cryo myself and love it as well, and I heard about the home stonewash/acid wash (PCB Etchant) and had to give it a try. I hurried through the whole process (veary eager to see the end result) and although I love the way it turned out (cosmetics) I think I damaged the little ball bearing on the frame lock because now I hear/feel it scratch (no function loss, just not as smooth as before).
I acid washed/stonewashed the blade as well as the scales and now that I have everything in place my blade has a slight blade play up/down, absolutely solid on side to side. So I was wondering if you have any ideas on how to fix this, if its even possible.
One more thing, during the acid wash process I used a harsh plastic brush to help take off the TiNi coating on the blade and scales (I used the brush as soon as I took it out of the etchant solution) and now the brush strokes are very evident, specially on my blade, what grade sandpaper would you suggest I use to "reset" it and make those marks less visible, or hopefully get rid of them.
Thanks for your quick response, once again, I love the way your cryo turned out and I regret even more not stumbling into this thread before... oh well
