Brief Description: Installed Upper Longeron Splice Bolts & Upper Fire
Finished installing the upper firewall former and upper longeron splice bolts tonight. I only spent an hour in the shop, but I felt good about getting these items accomplished. Just about ready to move on to plans page F10!
I countersunk the upper longerons for the flush head attach bolts, put a dab of paint on the countersink, and installed the bolts. I'm still amazed that the plans call for just the bolt and no washer underneath the nut. The -S54 bolt lenght is just a lttle long and too many threads show with out a AN960-10 washer being installed. This is a common theme all over the plans. I'm electing to install at least one washer under the nut to take up some of the extra length.
