Sickness Options

[Targa70]

Yes it is a sickness; and I believe other World members have it. I went so far as to transfer the stickers and felt bad from my broken fan housing to the new one. Only I will know.


Inspired by the crew here, I spent more hours than I should have on my blower. Though a hidden part, I am happy with my results.

I started with my original system paired with a donor system I purchased several years ago. I used Easy-Off to remove most all of the overspray, followed by a combination of 1000, 2000, Autsol, and Magic Eraser. New 914 Rubber seals and plated hardware finished if off. [attachmentid=673

If your sending your bits out for plating. Make sure they get baked.
Spring steel needs to be baked to keep from getting brittle.
Seems my batches are inconsistent at being baked so I'm going to make sure I request it next time I have springs in the batch. I haven't had one of the c clips break yet. But I've heard stories.

@cary , curious if you use any kind of acid to clean spring steel before having them plated and baked. I've read that acid clean can contribute to hydrogen embrittlement and I have used vinegar to dissolve heavy rust off many parts. My hope is that this kind of exposure to a mild acid isn't a problem. I also know the parts are typically dipped in strong acid prior to plating so I'm thinking as long as they are baked at the end of the process, it should be okay.

BTW, the US military found that long term exposure to Simple Green also causes hydrogen embrittlement. I learned that on a woodworking site because Simple Green is commonly used to clean pitch off of saw blades. Works great, but if you soak the blade overnight, you are asking for trouble.

No, not as a general rule. If plating is coming off sometimes I'll soak them in vinegar to remove. Going forward never on springs. Usual prep is blasting cabinet or wire wheel.

I'd like to thank everyone for the chemistry lesson.
