“No bird ever flew nonstop from New York to Tokyo, or raced 15 miles high at triple the speed of sound.                                                                                                   
  But birds do something else.
  They do not conquer the air; they romance it..”

Fuel Tanks work

Z-Brackets preparation - 05/01/2012 - 1h

Preparation work continues on the Z-brackets.

As the name says, the Z brackets have a Z shape aluminum form.

They are used to support and attach the fuel tanks to the main spar.

First you have to pre-drill them, them install to spar and matchdrill. Later the fuel tanks are fitted on top of them and matchdrilled from the top to ensure a good match between leading edge skin outboard and fuel tank skin.

This is a deviation from the plans. Vans manual follows another procedure but I will follow a method called the 'Dan Checkoway' method. It's known by most and you can find good illustrations on it on multiple websites. I will explain later as I move on to the matchdrilling part.

All brackets are edge cleaned and the center line is drawn on one side, ready to drill the center hole for the AN3 bolt.
