Finished covering removal from the airframe.
Ailerons shown here as covering removal begins. Experienced eureka moment - the strip ailerons are not solid wood - they're actually built-up structures! Additional pics show ailerons bare with covering removed; note the factory "X" pen marks - perhaps used to denote the bottoms of both ailerons...
Second to last pic shows all the covering from the airframe that was salvaged to cover other projects down the road or can be used to cover another BH Twister.
Last pic shows pristine spinner, hinges, and canopy salvaged from this airplane that can be used to support other projects in the future.
