Brief Description: Rib Flange Centreline Making Tool
Constructing the Empennage, and later the wings, involves drawing a centreline on the rib flange (5/16"). Unable to find photos on the web I made this. I'm sure there are better ways but its good enough for me.

ADDENDUM
When you come to mark the centreline of the Z brackets that support the fuel tank to the main spar they happen to be the same width! All I had to do was cut the wood slightly - so don't discard it!
