More drilling the Aileron counterweight pipe - 2 hours

I wasn't sure the best way to open up the #40 holes in the counterweight. I decided to set up to drill the pipe on the press. I will be able to put my drill jig to good use.

That was easy. Next step was to cleco the pipe back into the aileron, and drill out the #30 holes in the skin. Worked very well.

Once both ailerons were drilled. I needed to disassemble the leading edge and complete the #30 holes that are drilled from the backside.

I then disassembled the parts and looked everything over. All looked good, but I wasn't happy with some of the holes in the small tabs of the A-705 ribs. Some were slightly oblong just due to the way they were match drilled. So...It was an easy decision to replace with new. They are pretty cheap $6/each. The 'ol RV two step. Two steps forward, one back. lol.

I also placed a small order to cleveland for a CS4-4 countersink (The irony is I just ordered on a couple of weeks ago for a friend...Now I find that I need one...hahah)
