Office still closed for weather, but the airport is open and I have to travel for work. Flight was delayed until late afternoon, so I got a couple of hours in the shop before I left.
I completed the edge finishing and deburring for all the right tank ribs. Got the flange straightener out and ran all the ribs through to make all flanges 90 degrees to the web. Did spot checks with a square as I went, and all rib flanges checked good.
