Advice needed on rivet type

[SilverHoot]

Here are a couple of pics of my wheel well and my 'fix'. I bought a rivet gun and a bucking bar and am anxious to use them.I was thinking that I could rivet the new piece of 1/32" ( what gauge is that?)galvanized sheet to old wheel well. First I have treated all the rust with phosphoric acid, then I will paint all with SEM Rust Shield, then vulcem between old and new metal, then rivet. What type of rivet? I have aluminum buck rivets, oversized belly pan rivets, olympic rivets, but no steel solid rivets. If the steel solid are what would be recommended then what size and will a 3x gun and the bucking bar work for them? Or I am heading down the wrong path.

You certainly want to avoid mixing aluminum and steel, especially when exposed to salt and water. It's a perfect mix that will generate a ton of galvanic corrosion. To oversimplify, the more different the metals, the more corrosion you'll have.

I'd consider stainless pop rivets. Add a little dab of vulkem in the center to make sure they don't leak.

You'll have plenty of chances to buck!

You could use MS20615-4M4. these are monel steel solid shank rivets that are 1/8" in diameter and 1/4" long. These would be perfect for your galvinazied steel. They are a little softer then stainless steel and you can shoot them with your new 3X rivet gun.

Thanks Aerowood. Any advice on where to purchase in small quantities?

These people sell in 1/4 pound quantities. I don't know how much $$ though. I'll check my personal stock and see if I have some laying around. How many do you think you will need?

Genuine Aircraft Hardware Co.
