Hi guys,

   

  I'm starting to do a bit of solid riveting with my center spar and outboard wing spars. I've found that using a pneumatic gun gives me excellent control, and has me bucking solid rivets like a pro - although I haven't started riveting the actual parts yet. Here's my question though...

   

  I've been practicing using the "air chisel" that came with my compressor. The rivet sets have the same .401 shank, and fit into it perfectly. If I crank the regulator wide open on the tool itself, it will set the rivet almost perfectly in one or two reasonably short trigger pulls. As long as it does a good job and doesn't apparantly crack or otherwise damage the rivets, does anyone see any problem with using my "air chisel" instead of a dedicated "rivet gun?" In my uneducated perspective, they appear to do almost exactly the same thing, but I know that the rivet gun hammers more slowly. 

   

   Any good solid (no pun intended) advice on this would be appreciated. I'd rather not buy a tool to do exactly the same thing as the one I've got if there's no difference. And yes, I know a hammer will work too. I'm just looking for information from someone who knows more than I do about the subject. Build on my brothers!

Debo, the difference in the two hammer guns is that the gun designed for riveting has a variable speed trigger that allows the user a smack or two (depending on control techniques) with gentle pull and that can be important when starting a rivet in a difficult location. On the other hand, an air chisel has only the one speed, full blast, Best of luck, Bill

Debo,

  

 Just my opinion, but I believe a trained one,  Bill Phillips is mostly correct about the rivet guns versus Air Hammers. In  certain situations, an Air Hammer will get you by, but it would be a shame to  have a mess up at the end of a long line of rivets because the shooter couldn't  control that last blap! I'm not saying you can't do it because I'm sure it has  been done with a Air Hammer before. The big thing is no damage to the metal (  deformed ) and the rivet isn't cracked or overshot at the bucked tail. Maybe you  can borrow a good 3X gun from someone. You have to be pleased with the results  and the process that gets you there. Good luck - have fun.

Debo,

  

 I have an old 3X rivet gun you can use. It's just  sitting in the drawer. I can send it to you if you want it.

I have been following this thread for some time. I also made my own spars several; years ago now. I did the riveting by hand by making fixture similar to those you can buy. I bought a :"socket " that fit the rivet head and a "C clamp " fixture that held a rod that rested on the worked end of the rivet. I found it took two blows with a heavy hammer, once I had that figured out it was just put in the rivet bang bang and on to the next. I think I drilled out two or three rivets in total for all three spars.
