January 5, 2006 - Skin Prep 

The next week or so will be spent prepping all the components for riveting:  de-vinyled, deburring, edge-smoothing, drilling, countersinking, dimpling, scotch-briting, cleaning and priming.  It's not real glamorous work.  It doesn't make for real interesting pictures either so I don't have one for every little thing.  I did make a checklist of all the things I needed to get done prior to riveting.

My son Joe devinyled and deburred the bottom skin and one of the side skins for me  Here's the outer side of the bottom skin devinyled and deburred. 

Then I took over, smoothing the edges and dimpling the edge holes. 
This is one of the side skins.  I proceeded with great caution here, because there are sets of holes that don't get dimpled.  Per the drawings, I marked the skin with a Sharpie all the holes that don't get dimpled. 
I marked up the outer side as well.  I marked the "specialty" holes that get drilled out to the larger sizes like 5/8", 1", 7/16".
