Chassis stiffening kit patterns Options

[partwerks]

Would anyone happen to have paper drawings/pattern for making the plates for the chassis stiffening kit that I could use to copy over to the sheet metal to make the plates?

I made my own set because I wanted it to be galvanized as all my patches and Maddog said that it'd be too expensive to cut just 1 custom set for me. If you don't needed it to be customized, then just buy it, he charges about $50 over the price of raw material (according to my calculations). Also, I enjoy metal fabrication, so I did everything myself from drawing templates to cutting metal to welding. But if you're going to pay somebody to do it, then I guess it's just easier to buy finished product.

As far as the question of what's better Engman kit or this, let me say that I have them both (Engman not yet installed). I know a guy who has Engman kit installed and he says that it didn't do much for him, which is not what the majority on this board thinks though.

You were welding galvanized steel???? (IMG:style_emoticons/default/WTF.gif)

Yes, I did both galvanized and galvanneal. All Porsches from 77 going forward are galvanized.

I believe that Clay is pointing out that you are putting yourself at risk by welding galvanized steel. It puts out some seriously nasty fumes. At a minimum, you need to grind off any galvanizing on and around your welds. For the stiffening kit, that would pretty much be all of it.

Or you could just hold your breath the whole time (IMG:style_emoticons/default/welder.gif)

Thank you for the concern, but I do all my welding outside with fan, so ventilation is very good (needless to say that I don't use gas (IMG:style_emoticons/default/dry.gif) ). I don't want to sound argumentative, but I have heard of the health hazards of welding galvanized and did a rather extensive research on the topic. I've read about flu like symptoms and such, but there is no definitive and conclusive evidence of permanent health risk. If you know of any research articles to the contrary, I would love to read them. My second point is that Restoration Design - a premier provider of sheet metal panels - uses galvanneal steel. I asked Peter that question, here's the thread, page #3, posts #3 and #4

And my last point is how they fix body panels of modern day galvanized cars. I realize that some panels are glued, riveted etc., but there must be some welding done.
Also, take a look at content of weld thru primers, they consist of 93-95% zinc. I just purchased Engman kit and it came with weld thru primer as well which I think is a great idea.

I have to weigh in here being a perfesser doing real tox studies. I did a VERY quick medline search and found that zinc welding is associated with metal fume fever (MFF). Which is as you say flu like and associated with an inflammatory response. It sounds like if you are consistently upwind of the fumes you would be OK. (The kind of OK I am while spraying 2-part urethane paint with supplied air and still feeling a bit of a cough - not really OK.) Most of the studies involve people who do this a lot, especially in asia. With that said I saw a few serious case studies including a case of meningitis, which might have been coincidental. That wouldn't stop me from working with the stuff, but then I am an IDIOT. Be cautious.
