You would very quickly notice if there was a problem with adhesion, voids would be visible, and it would be possible to lift the edge of the lay up, don't ask me how I know.

On page 29-2 Issue 3. It states to lay up two plies of "bid" at 45 degrees over the entire are up to the top level of the central tunnel. I just did one ply and it was the most difficult lay up so far. There are no measuremnts given and the cloth folds onto its self while I tried to do the lay up. It seems the there should be a better way of doing this lay-up. Has somebody come up with a good method? I looked at all the pictures, but they only show the finished product. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
