2.7 hrs
The order from Van's arrived just as I got home today. In it was a tail tied down ring, an Odyssey battery install kit, and the new control column mount brackets. So layed out and match drilled the brackets to the 904 aft bulkhead. This time correctly drilling to 3/16". Started the radius holes for lightening the brackets. I'll work on those as a subtask.
Deburred all 705 parts that had already been cut and sanded.
Cut the 604C doublers, shaped, and deburred them.
Then started on assembly. Clamped the 704B center section bar to 704A. Looked at the clock and decided to stop. Need sleep.
