K8b restoration

I think you will find that all wooden Schleicher gliders have been finished
from the factory with fabric up to 50 mm forward of the rear face of the
main spar, and with paint on the D-box. Sometimes the D-box has been
reworked (especially on Ka6s) with a thin layer of filler to reduce drag.
In fact, reducing drag by creating a smooth painted surface opposed to a
more rough fabric'ed D-nose is probably the main reason it was finished
this way. Fabric width was no problem.

What glue is recommended for fixing broken glue joints? I understand that the original glue was not the best--very brittle.

This topic was covered in Bungee Cord articles published by the Vintage Sailplane Association (also VGC News). There is not a simple answer, since all IA's and FAA personnel are not the same. I've sent you a separate, private email on this topic. ..... Neal
