Fellow builders,
I decided to work on the fiberglass tips on my empennage while
waiting on my wing kit. The newer RV-7 elevators have lead
counterweights that stick out, rather than lie flush inside the
counterbalance arm. The fiberglass tip covers the sides of the lead
counterweight nicely, but the forward end is exposed and it shows.
The tip doesn't cover it. I'm wondering how to cover it. How are you
guys doing it? I've looked at a lot of web sites, but I haven't
found anybody yet that details how they did this. I'm looking for
some details and/or pictures.
It's very tempting to just slather on some super-fill or some
Evercoat Rage or whatever, and sand it down smooth and contour
it. But I'm wondering how well these materials stick to lead? Has
anybody researched this? And what about avoiding cracks developing
over time? It seems to me there should be at least one layer of bid
fiberglass over the lead, bonded to the fiberglass tip. Has anyone
done this? Any suggestions or pictures?
Thanks!
Bruce Swayze

I scored up the lead pretty well before installing the tips, then packed epoxy/flox mixture in around the weight forcing the mixture back some around the edges between the tip and weight, hoping this will stabilize it. Then I laid a patch of fine (6-8 oz.?) fiberglass cloth around the whole thing & smoothed/finished. Looks good so far (no paint yet) but not saying this is best method either. Kinda think the old style may have been an improvement...

My brother in Atlanta just finished his tips. You may want to visit his
website for ideas. http://www.n713db.com/ I've still got to do my tips so
let us know what you decide.

So you and your brother are both building the same plane? Very cool!

Yes, the same plane. He is going the slow build route so I'm giving him a few months head start before I order my quick build. I tried to convince him to build an 8 so we could trade off, but no luck.

Dale,
Not yet. I'm building a new home in Denver, NC and hope to be moved in by
Sept-Oct. I'll order the QB then and have it delivered to the new home. I
wont have time to work on it until after I move in. I'll keep you updated.
