Top Deflection Studies - Ovation Guitar Top Deflection Engineering Memos and Test Data (1973-1976)

1973 US 10 pages

This document is a collection of internal engineering memos and test data from Kaman/Ovation's Materials & Process Engineering department, primarily authored by A. L. Belbruno, spanning 1973 to 1976. The memos record top deflection measurements (in inches per 20 lbs) for various Ovation guitar models and bowl prototypes, including Glen Campbell signature models and standard production guitars. The documents track quality control and structural testing data related to guitar top stiffness under string tension and load conditions.
