We've been gone to my BIL's wedding so I didn't get much done yesterday or today. When we returned I found the notice on the door about our gas being shut-off for a leak. I apparently cut the service to the house yesterday morning doing fence repairs. I don't know if that was before or after I stepped in the fire ant nest and got my feet bitten up.
This evening I cut the notches in the ends of the center ribs. Then I used them to help line everything up to drill, screw and glue.
Aw nuts. I had the whole thing clamped together and already drilled when I realized I swapped the left and right side ribs. I didn't want to re-drill, so I will adjust the notches at the bottom ends.
