I've got a somewhat different issue, although it does involve a small dent in my rudder, and rather than start a new thread I though I would plumb the depths of the minds on this one. When I was putting my rudder halves together on my -14, the stiffeners on either rudder half are fastened together with those LP4-3 pop rivets. Well when I was pulling the squeezer for one of those rivets and it finally "popped", the rivet gun jerked back and down, hitting the sheet metal on the half that was laying flat on my work bench. It put a very small pimple like dent in the sheet metal. So, looking at the rudder from the outside, it literally looks like a pimple sticking out. No more than 1/16 or even 1/32 high. Before I rivet in the rudder assembly structure, which would seal off access to the inside of the rudder, is there any technique I can use to reduce this small dent, or even eliminate it? Or do I just chalk it up to garage-rash? Remember, it's a dent from the inside pushing out.
