Brief Description: Installing temporary firewall to jig
Adjusting the temporary firewall with clamps so that it is centred over the plank, level, and the tip of the longerons will be 23" above the plank.
I ensured that the 23" height from the plank to the line where the top of the fuselage sides will be. The temporary firewall was centred to the plank and leveled using a plumb bob.
Once these criteria were met then 4 holes were drilled through the bottom of the temp firewall and into the 2x4s and screws inserted.
