1.Flip tail cone bottom down (using 2x4 blocks or proper saw horse spacing as before to keep protect any clecos in TC bottom)
2.Remove aft deck
3.Temporarily clamp the P-F-TC-VT upper mount (p6506) into place as shown on plans sheet P-F-TC-tail cone top/ formers (top view) to stabilize the upper longerons
4.Clamp the P-F-TC bulk head 4 reinforcements (P6507 and P6508) in place as shown on plans sheet P-F-TC lower TC and P-F-TC bulkheads /misc details, using small C clamps and photos as a guide
Note: You may need to slightly bevel the outer top corners of the reinforcements to clear the “radius” on inside of upper longerons. See P-F-TC-bulkheads/misc details (bulkhead 3 and 4 details)
5.Drill the P-F-TC-bulkhead 4 reinforcements to bulk head #4 with #40 bit and cleco in place
6.Move forward and clamp a scrap of angle or straight board across the upper longeron behind bulkhead 3 as shown in photo below to stabilize the longerons
7.Clamp the P-F-TC bulk head 3 reinforcements (P6504 and P6505) in place as shown on plans sheet P-F-TC lower TC and P-F-TC bulkheads /misc details, using small C clamps and photos as a guide
Note: You may need to slightly bevel the outer top corners of the reinforcements to clear the “radius” on inside of upper longerons. See P-F-TC-bulkheads/misc details (bulkhead 3 and 4 details)
8.Drill the P-F-TC-bulkhead 3 reinforcements to bulk head #3 with #40 bit and cleco in place
9.Up drill all P-F-TC reinforcement holes to # 30 and cleco.
10.Up drill any remaining Aft deck holes to #30 and cleco.
11.Remove Aft top skin and former 4.
12.Drill the forward outer holes in aft deck through longeron #40.
13.Layout holes at bulkhead 1 and 2 (qty4) at top longeron per plans sheet P-F-TC-lower TC (top view dashed circle).
14.Drill and cleco#40 then up drill #30.
15.Reinstall former #4 and top TC skin with clecos.
16.From bottom side drill the forward outer aft deck holes through the longeron and former 4.
17.From bottom up drill these holes and remaining aft deck to former #4 to #30 and cleco (see photo below).
