Brief Description: Front Spar Preparation and Rudder Stops
I ran through the steps pretty quickly today with no major hitches. A couple of observations along the way though...
I am running my pneumatic squeezer at 90psi and it squeezes very well, however the dimples in thicker metal have a very rounded edge to them. As a result, when countersinking the front spar doubler, the dimple would not sit into the countersink as well as I would have liked leaving a fine but visible gap between the sheets. When I tidied up the dimples with the C Frame, the edges of the dimples were much crisper and the parts fit together like a glove. The spar is quite thick so I am guiessing that this is the issue. I used Cleaveland dimples in both tools, so no difference there.
I then set to work and cleaned up the rudder stops. They are much smaller than you would expect them to be... The cleaned up well on the scotchbrite wheel.
