A6 Rivet question TIM- On the rivets that have stems that keep you from drilling and cause the drill to go off-center and make a mess- Use a center punch and a light hammer and try to drive the stem back into yhe opposte end . Then try drilling the rivet hear off. Sometimes it takes a few tries to drive the rivet center in. Be carefull you don't bend or dent the aluminum skin. I did have to use a few #6 rivets a couple years ago when I opened the leading edge on both wings to take out the two aux. tanks but don't remember which pulling head I used. Presently, I have both wings off with the topskins removed along with both leading edge skins. Also, the center section srar is out. I have stripped both spars fron the wings for easier handling. I have decided bolt yhe new heavy angles onto the spars after trying unsucessfully to rivet. The left wing will be closed and finished in about a week or two. Then comes the right wing and then the center spar and fuselage work. Looks like an all summer job. If you get a chance take a trip down and see my slow progress.

If you used countersunk rivets did you pull them with the nosepiece ground for the A5 rivet or make a new one? I used A6 rivets that I bought from Zenith. They are the countersunk type, just like the A4's and A5's we already use, just a little bigger. I bought a bigger hand riveter and ground out one of the nosepieces that came with it. For removing the pre-existing rivets, I used one of those $3 "spring punches". I ground down the tip so it could fit into the holes in the rivets. For each rivet I would punch down the stem, and then using a drill bit *larger* than the existing rivet, I would carefully drill into the rivet head until it popped off (without touching the underlying skin or enlarging the existing hole). Then most rivets could be pushed out the rest of the way with a second pop from the spring punch. Stubborn ones got drilled out with a smaller drill so as to not enlarge the existing hole. A4's are harder to remove than A5's, as A4's more often tend to "spin". To get around that, I carefully drill into their heads at an acute angle until the heads come off. It took a while, but I've got one wing just about done now. By far the biggest problem I've had is "garage rash" as these skins are taking a beating and getting all scratched no matter how careful I am. I want to polish my skins, but I don't know how it will look with some of the scratches I can already see. -------- Patrick XL/650/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=298574#298574 ________________________________ Message 4 _____________________________________ Time: 07:23:56 AM PST US From: "Paul Mulwitz" Subject: RE: Zenith601-List: Re: Oops! A6 Rivet question Hi Patrick, I have found a slightly different approach for removing rivets. I do nothing before drilling, and use the same size drill bit as the final rivet hole. I drill very slowly - using a variable speed battery powered drill. Most of the time the head starts to spin when the drill bit reaches the skin and I am finished. In cases where the stem gets in the way the drill bit goes off center and I stop before the bit reaches the skin. Then I use a normal wood chisel and mallet to tap off the remaining part of the rivet head. With the rivet partially drilled this goes very easily. I have done a lot of wood work over the years, so it is easy for me to position the wood chisel so it doesn't damage the skin. For less experienced wood workers, I would recommend a little practice in partially drilled rivets in scrap pieces. After the rivet head is removed, I use a slightly smaller pin punch and mallet to remove the remains from the hole. Some times this makes a bit of a dent in the skin, but this is easily removed with auto body dolly and hammer. ------ For removing the pre-existing rivets, I used one of those $3 "spring punches".

The polishing process is designed to remove them. If you have deep scratches you should probably smooth them out with emery cloth, but the shallow ones will be polished out without much extra effort. ----- It took a while, but I've got one wing just about done now.

A6 Rivet question From: "Tim Juhl" I used a spring loaded center punch to attempt to drive out the pin with no success. Also tried a punch and a few gentle taps from a hammer... no luck. Even worse, the top of the pin was broken on an angle resulting in the drill trying to walk off center. I ended up using a #40 drill to start it while holding the drill centered (as best as I could get it) with a drilling cup. This happened only in the A5 rivets and to about 6 in the top skin.

A6 Rivet question From: afterfxllc@aol.com If your aircraft isn't painted you can use a wood chisel to remove all riv ets and leave no dents and it makes the tail removal much easier also. I use a chisel to remove the solid rivet heads then just punch out the sho p end with a punch and hammer over a vise. I have gotten to the point that I can disassemble the center spar and remove all the rivets in 30 minutes . I do the same with the wing spar but I have to drill half way thru them and use my 2X to punch the shop end out. If you use a chisel you need to smooth the bottom so it doesn't scratch or gouge the aluminum.

No one is concerned that the bolts are breaking. Did it ever occur to you that the reason that spar broke at that hole was because perhaps the fit between the bolt and the hole was too loose and it was able to work the hole open further until it finally broke? Or maybe it was one of those sloppy building techniques you mentioned earlier that hadn't failed yet but finally did?

How are you planning to have the narrow front part slide over the wider back part? I've been thinking about this, and it seem like the canopy would have to lift up, a lot, more than on an RV, before sliding. For what it's worth, the 601 also has more head and leg room the than an RV7 (only one I've attempted to get into - and failed). I really hope you do this, I'd love to see your solution.

A6 Rivet question From: "w8n2bup" I too, spent 2 years occasionally needing to remove a rivet only to run into the stem and over sizing the hole. Then I heard from Mr. Garrett on the use of a chisel. I absolutely could not believe I had never heard of this technique before. I use a half inch wood chisel and have removed several hundred rivets now and everyone of them left the hole completely untouched. The head just shears right off and the back of the rivet can be pulled out with a pair of dikes or pliers or if necessary, a light tap of a punch. I do not have any painted parts but with the flat side polished a little, it leaves very little in the way of a mark. In addition, you can get to any head at any angle unlike a drill. I don't believe I will ever drill out another rivet. Try it. You just won't believe it !
