Spent some time preparing the parts for spraying. Set up the racks for holding the big parts vertically. Decided to try vertical sparying this time with all the parts that I had to do. I figured the parts could be moved between the spraying rack to the holding rack as they are sprayed. This should minimize overspray getting on newly sprayed surfaces. Put a vertical board on the table rack to minimize overspray here as well. I still have a lot to learn about spraying.I also prepared the hinge pins for the flap hinges. I chose to use the alternative method for pinning the hinges. This called for removing a number of himge tabs in the middle of the hinges and bending the hinge pins to allow them to be safety wired to the bottom wing skin. I still need to make one more bend to allow the pins to do this, but They're pretty close at this point.
