Brief Description:  Deburr, scour, clean, and prime new aileron joints

Followed my standard prep to prepare for riveting—almost.

1) Deburred all holes.

2) Scoured joint lines with Scotch Brite

3) Cleaned joint lines with camp fuel on a paper towel

a) Discovered that the MEK I had been using would dissolve the primer on surfaces already primed.
b) The camp fuel is much less noxious than the MEK.
c) I bought some blue nitrile rubber gloves from Harbor Freight. They appear to protect from both MEK and camp fuel, at least for the short-time exposure in cleaning joints.

4) The final step was to prime the joint lines with Cortec 703.

5) In a significant mistake, I did not vacuum out the interior of the ailerons before priming. Upon inspection of the primed flange for the piano hinge joint, I discovered that lots of metal chips from drilling, etc., had migrated to the wet Cortec 703 primer and were now embedded in the joint line primer. See Fig. 1. I’ll have to remove the chips before I can rivet. Undoubtedly, I had learned this lesson 3 years ago before my building was stopped because of the accidents. But I forgot the importance of the vacuum cleanup. I hope I don’t have to relearn too much else.
