Step 3 - Consider also using the center line on the back of the AEX tie down as an additional reference to center the AEX to the centerline of the F-1012A bulkhead.

- 5/28/22 I did it per the plans, drawing the two lines exactly. Now use a cleco CLAMP on the bottom (threaded end) and a wood C clamp on the top gently holding it in place while you drill the 4 holes. A little confusing in the plans it calls to drill the 3/32 out w/ a # 30 drill. Correct. It's a 3/32 hole oversize it to #30 so it will receive a -4 (4/32) rivet down line. See page 10-18 for rivet size. Drill the 4 #30 holes first and cleco as you go. Then drill the 3/16 holes also clecoing if you have 3/16 clecos. | |||

Step 1: 5/28/22 Taping the Tie down. Note: The hole should first be drilled out to 5/16 to receive a 3/8-16 tap. The hole is undersized by Vans. A trick a machinist taught me, put the tap in your drill press and center your piece under while turning the tap BY HAND. DON'T turn on the drill! It's just a jig to keep things straight while you start the tap. Once you get a couple turns on the tap, take it out, put in your vice and finish. | |||
