Just a quick trip to the shop after dinner and cleaning up to do some countersinking on the firewall stiffners. I have learned now that taking a little time to think the next step through, label carefully, and plan makes the work so much more efficient. I took my time assembling and labeling all the firewall parts and I saw the results tonight when I just walked into the garage, checked the depth of my countersink and started working instead of staring at the instructions and trying to work everything out in my head first.
Label meticulously and the work goes so much faster
