* Step2<br>Instead of drilling F-1013 through the F-1039J jig at this point, it is much easier (and more accurate) to wait until the F-1013 is removed and then drill these holes on the bench.  I found it is more important to ensure that the F-1039J jig edge is parallel to the edge of F-1013 than to use the #30 rivet holes to set this. If those #30 holes are slightly off, the error will be magnified in the position of the rudder assembly bolt holes.  If the F-1039J is not parallel to F-1013, remove all but one cleco, then make the jig parallel, then drill the most aft of the bolt holes.  Cleco this hole and drill the remaining bolt holes.

* Step 5<br>When match drilling from the F-1001B angle into the WD-1002-L / WD-1002-R firewall steel brackets, be aware that it's easy to violate the edge distance in the steel bracket (2 x D, measured from the center of hole). The remedy is to temporarily install a bolt into the engine mount hole to pull the bracket into place and to use a clamp to move the steel bracket to increase edge distance.<br>See [http://www.mykitlog.com/users/display_log.php?user=nbnrv10&project=572&category=6009&log=254638&row=60 this build log]<br>[[File:Screen Shot 2024-01-22 at 11.29.55 AM.png|300x300px]]
