I finished deburring the spars and doubler tonight, and just have the skin left to debur on the vertical stabilizer. It’s been very time consuming, but I’m striving for a good finish, and doing most of this with scotchbrite by hand. I’m also going beyond just deburring and actually scuffing the surface. This will be required when applying primer anyway, but it’s more that iMm using the scotchbrite to debur the holes, rather than other tools. I don’t like the idea of accidentally counter sinking while deburring, and this approach seems to be producing good results. Hopefully the skin will be a quick debur project that I can complete tomorrow, so I can move on to the next steps; dimpling and counter sinking. Once those steps are done, I’ll prime all parts (including the inside of the skin where parts will be touching), and then I can start riveting. I can see why the parts of the kit with already-final sized holes will go together so much faster. I also spent some time reviewing hints for home builders videos and reading through the digitized plans with links to Vans forum posts. Extremely helpful.
