I'm about to start riveting the right elevator skin to the stiffners on

my RV-8 project. Next will be the elevator skeleton. 



The plans call for significant trimming of the elevator lead

counterweights. 

Anybody have any good advice for me on the best way to do this? 



Right now I am thinking of marking the weight as per the plans and using

my band saw to cut out the major block and then either smooth the edges

with the 3M wheel or a file or a combo.



Also, the plans suggest back riveting the stiffners to the skin. I found

that increasingly hard to do on the rudder as I got closer to the

trailing edge fold.



Have heard two alternative suggestions to forcing the back rivet process

into the narrow area. One was to use the pop-rivets and the other was to

use a slim bucking bar and set those difficult rivets from the skin

side.



Advice is welcome.



Thanks,

Just mount them with the bolts for now....Later you can take a large

drill bit and drill several holes in the lead to remove material until

the elevators balance. After they are painted you will not notice the

holes....

Gail,



1. How quickly one forgets these things... I spent a while googling  

for ideas on how to do the shaping of the counter weight too. In the  

end I used a saw, a course file, and a bunch of patience. Here's what  

I wrote in my blog about it: http://blog.jason.hills.org/blog/ 

_archives/2006/10/2/2382197.html



2. I was able to back rivet all of the rivets for the stiffiners on  

both elevators. Assuming you haven't bent the trailing edge yet  

(should not have done that yet), go ahead and gently pry it open wide  

enough to get the rivet gun all the way back there. I did it after an  

experienced RV builder showed me, and assured me I wasn't going to  

hurt anything, as it seemed like I was really prying on things to get  

in there. After you've done a few it doesn't seem too bad. I did the  

tightest two rivets on each stiffener last. I started my whole RV-8  

project with the right elevator, so I did this on my first real day  

of building, but I didn't write anything interesting about doing the  

back riveting in my blog (http://blog.jason.hills.org/blog/_archives/ 

2006/9/30/2376912.html).
