Need some ideas guys on shock mount

White viniger is also used to etch/put a "tooth" on a/some metallic surfaces before painting.

Thanks for the information ntsqd.

Now that is to remove anti corrosion coatings like zinc and whatever they treat" plain" nuts with, or for scale from mfr? Could be really helpful for me if it works on galvi as well, as that is the only steel I can buy local over the counter

Good galv may need a longer soak, but cheap galv is usually a matter of a couple of hours immersion time.

[Ol'fogasaurus]

Galv...nasty stuff (cuts) and dangerous to weld (off-gassing, it can turn your schooling into wasted time and money)! I don't know if it will work Fuser, sorry.

I've used vinegar on cheap galv with good results. Just don't know how good the galv you're getting is. If it takes more than a couple of hours to remove a plating I agitate the part in the vinegar periodically. A decent sized Tupperware works great for holding the used vinegar and keeping the smell under control. I usually suspend the parts with stainless safety wire and close the lid down over the wire. This way I don't have to get my hands in the vinegar.

I've used vinegar to remove corrosion from fuse block terminals. A recommendation to try it for that exact use is what got me going on also using it to remove the various platings. I now buy it by the gallon from Smart & Final.

I went to my larger sized washer box and found a washer that is 2.32" in diameter and .06 thick. The washer had a bright coating on it and I spent a few minutes with it first with lacquer thinner then in the blast cabinet. It looks good, an AL color and soft material but I have kind of a gut feeling that it may be CRES/SS; any good way to tell. I did hold it against a magnet and it took hold but not all SS does not react to magnets.

Before I get too far and can't weld, or if there is going to be a trick to this, I need some more advice. This washer is going to be a best fit candidate but not the only choice I have.

Blasting it didn't get all of the plating off. BT, DT. Grinding or sanding it won't either. BT, DT too.

At some point you punt and move past that project, so I get that. I'm not convinced that welding zinc plated metal is as bad for you as it is made out to be. Heat zinc up in the presence of oxygen and you get zinc oxide. That same white stuff that you put on your nose to keep from burning it in the sun. Shouldn't be breathing it no doubt, but I don't think that it's the truly evil villain that it's made out to be either. Search out who the authors of the attachment are if you question it.

It’s the off-gassing fumes that are so bad to breathe from what I have been told many times. Also, the galvanizing will melt during welding and drip off and burn someone who is welding from underneath (“Why didn’t you tell me it was galvanized!” “I didn’t know that they were doing that!” It was on the stub frame for a Pinto when I was putting a v-8 into it), I have seen that happen before; nasty bad burns even though gloves… and it was from my car!

Grinding I was just told was a way to see if it is CRES or carbon steel. It is the color of the sparks that will tell you. CRES/SS sparks should be in the blue range and carbon will be in the yellow to white range.

Wikipedia on 'Hot-dip galvanizing' http://en.wikipedia.org/wiki/Hot-dip_galvanizing: "... Galvanized steel can be welded; however, one must exercise caution around the resulting zinc fumes." http://www.omfi.hu/cejoem/Volume13/Vol1 ... -4-04.html http://www.cpwr.com/hazpdfs/kfwelding.pdf http://www.finishing.com/85/35.shtml and so on.

It seems like Zinc is the nasty part of the concoction.

Did you see my attachment?

[Ol'fogasaurus]

No, it doesn't let me look at it, only save it.

I downloaded it, the computer sees it but no access is available even with using search functions.

[ntsqd]

It's a pdf file, should be able to open it with a free download form Adobe if not at least one other entity.

[Ol'fogasaurus]

I tried both and nothing. I tried to down load another adobe file to help and it would not load correctly. I have had trouble with adobe on this computer for some reason.

Started on the patch piece late today and got it farther along than I thought I would.



This is the area I am trying to fix.



The washer I used was softer than I though and it pulled into place after some initial work on the edges using a partly open vice and a body man’s pick hammer; hence all the whack marks. I have had the fill piece off once and it is holding shape quite well. Tomorrow I will blue the area and prepare to try to match the contour of the washer and the shock tower. I expect I will have to cut both pieces of metal to get them to seat in together. Again, I am worried about the soft washer material and welding it but a lot of tacks do a lot of fixin’ of soft metal problems. If it doesn't work I will try something else and try to shape it.
