On the plans there is a rivet designation and arrow pointing to this particular rivet and it says, "AN426AD4-4.5 spar to skin counterbalance skin rivets". The one on the front side of the spar, top & bottom is almost impossible to buck with anything I have, and I do have a fair selection of bucking bars. Can squeeze it as you have to go around a corner. On the right elevator I slid a heavy bar down the leading edge and was able to reach between the leading edge and the rib with one finger to hold the bucking bar in place. Didn't work well, vibrated out of place and left an impression of the rib flange in the skin. I would like to do better on the left elevator. How did you guys do it? I have seen some -9's with a pop rivet here. Which pop rivet is appropriate? Thanks.

This rivet will fit the #40 dimple very well. Just drill the hole to 7/64 and install pop rivet. It gives you a nice flush fit. If you don't want to see this rivet, then fill with filler during the final paint process. Then again you probably already knew that. :) Bryon Crook ________________________________ Message 3 _____________________________________ Time: 12:58:22 PM PST US From: "D, C, Jones" Subject: Re: RV9-List: How did you buck this rivet? pts rule name description ---- ---------------------- ------------------------------------------- --> RV9-List message posted by: "D, C, Jones" I used a 3/8" wide bar about 8" long and very carefully bucked it. It went very well. I hate pop rivets! Also, I used solid rivets on the bottom skin to spar rivets. My plans call for AN426AD3-4.5, not 4-4.5 Cliff ----- Original Message ----- From: "Richard Scott" description ---- ---------------------- ------------------------------------ ------- > --> RV9-List message posted by: Richard Scott > > Outboard end of elevator, front side of spar, just inside the tip rib.

I sawed off the forks on the hooked end of the crowbar, and after polishing it I used it to get into the tight space to buck that troublesome rivet that you refer to.
