Hi Brian, I am doing a ground vibration test on their Albatros. It had a reputation for lower wing flutter during the war, even if they did not know why the lower wing was falling off. TVA is building a small production and want to know how it can be prevented. I am doing this with a German company which has a lot of experience in flutter testing. It is a rather interesting project. I expect we will be done with it in a week or so and I hope to have some time available afterwards to look around and maybe visit with people I know. My flight home is May 14. I do not know the people you mentioned. That is neat that you have that little biplane. I hope you can get the rest of the 90% done some time soon.

Managed to find some offcuts from a repair shop, of just the right gauge. The aluminium has protective plastic material [very light grey colour] on both surfaces. Normally this protective coating is pretty easy to peel off, leaving a nice clean and shiny surface underneath. The trouble is, these offcuts had been sitting around for quite a long time. It seems that the plastic that was more exposed to light has become, well, less plastic, more brittle, and the adhesive seems to have a tighter grip. So getting the plastic layer off now is an issue. Is there some way of rejuvenating the plastic to restore its suppleness and tensile strength, or some way of defeating the adhesive bond, without making a total mess. Suggestions welcomed.

It works to take the OLD paper off Plexiglas sheets. PS, I still have a forward canopy slide pin if anyone needs one.

This has worked for me using a hair drier to softener the plastic and make the glue more pliable again.
