Hi everyone! I'm glad my brain is still functioning! Filing it is a possible option. I guess that depends on me and how much time I'm willing to put in this. So I'm going to try the weak nitric way, and I wanted to try the lye way too, but that's scary. Even on the bottle it says not to get near Aluminum. I'm living right in town now, and I really don't want Hazmat showing up at my door, first accusing me of cooking dope, and then just kicking me out of town. Happened before when I lived in Mtn. View, CA. (That was over 25 years ago!) But the lye way, seems the fast way. Can I dilute the lye somehow? Doesn't it react with water?
Also, I've found that I've got two types of metal housings. The other one is magnetic! It looks like stainless steel, but it's magnetic and doesn't get all rusty and corroded in nitric. Is it OK if I post a picture of these things?
