Dad came over this afternoon and helped hold the wings as I drilled out the flap and aileron gap fairings. Then he got to work at one of his favorite jobs... deburring:-) I continued work on the aileron brackets. I coutersunk the correct holes (I hope) and started riveting the pieces together. I was able to use the sqeezer for 80% of them. I'll have to use the rivet gun and bucking bar on the rest.
