I finished with the fuel tank installation in the left wing. I was able to shave several hours off the time required for the first fuel tank. I imaging if one were to build a second Bearhawk he could do it a significantly shorter time than the first. I've become quite good at making the fuel tank straps. On this wing I used a different method for marking the location in the fuel tank access door for the fuel drain valve. On the right wing I just carefully measured about a half dozen times and was lucky that the hole came out in the right spot. On this wing I installed the Saf-Air fuel tank drain valve. Then I cut the head off of a #5 rivet and stuck it in the hole in the drain valve. I installed the fuel tank access door using only the two corner screws in the front of the door. Then I lifted up the back edge of the access door and put a drop of torque seal on the rivet. Then I lowered the access door down onto the rivet and the torque seal left a mark on the access door in exactly the spot where I was to drill. A 3/4" hole with my Unibit and I have a perfectly placed hole for the drain valve.
