6.5 hrs, 12 rivets
Fit carb heat door to hinges. Fit door and hinges to airbox. Finish drilling hinges, spacers, door, and control arm to airbox top.
Fit Robbins Wings carb heat flange to airbox. I had to modify this to fit. My airbox is cut fairly short, and the flange was not going to fit as is. Made it work, but it was a challenge, and it will require pop rivets on the forward end.
Drill airbox top and filter clips for platenuts, dimple, install platenuts.
Drill control arm for cable attach, prime, paint.
I missed several days of building because I got too busy. A FAA safety seminar on Thursday, driving to Dallas on Friday, all day Condition Inspection class on Saturday, followed by driving back to Austin. Lucky Loucke and Mel Asberry taught the inspection class, and it was well worth the time and expense.
