(AWM) Awaiting Maintenance as we say in the military. Thanks for those pictures they will help immensely.

It wouldn't take much effort to remove the sheeting and Epoxy that Bellcrank in. Also it would benefit you to reglue all the joints. Never trust old glue.

Thanks Ron... That's the advice I wanted to hear... at least for the bell-crank mount. The "thicker than spec." wing-ribs have me concerned about weight... so I would have to be careful with re-gluing all the joints. Do you think spot-gluing the ribs/spar-joints with thin CA might be enough? It would be the light-weight option. Definitely epoxy on the bell-crank mount.

As told to me you want to scrape away as much old glue from the joint as possible and re-glue with the same type as originally used. In your case it was probably ambroid. You can still find ambroid, but not real easy. Check Ebay first. Failing that Sig-Ment and Duco are similar and easily found.

Thanks Ron... I'll take your advice. I have Ambroid... and it's still available locally, in case my tube has dried up. It used to be made in Taunton, MA... about 15 mi. away from me! Don't know if it still is.

There's some "oldies" there... I keep em' for the memories!

....and I have riffler rasp/file sets that would be perfect for the task of scraping the old glue out.

haha... The tube says "Ambroid" at the bottom... but the rest of the label is in Spanish! We had a sm. chain of "railroad salvage" outlets up here in the Boston, MA area called "Building 19"... everything was in brown unmarked cardboard boxes on tables/shelves... There was a box full of the "Cemento" tubes... I think they were 25 cents ea. and I grabbed a handful when I read "Ambroid" on the bottom... I love those places!
