Started day at 40 degrees in shop. Dick was here and helped out some. Match drilled the doublers to the side skin and countersunk the CS4-4 locations on the smaller doublers. Found it was just too cold to work in the shop (garage) so picked up a small propane blower from Lowes which added 20 degrees to the shop by running it for less than an hour. (ie got it up to 60 degrees before it slowly cooled to 50).
Deburred all the doublers and brackets and primed them.
Cool 40F start to the day
Primed fuse areas for the doublers.
