Surface prep discs

Today my friend Niels came over and we cleco’d together the forward spar. I received some very fine (blue) and super fine (white) surface prep discs from Pan American Tool and we tried blending out the scratches from using the medium (maroon) discs. They were pretty deep and I was worried about removing too much material blending them out so I decided not to polish before riveting and just did a pass with the blue and then the white discs.

In the future I’m going to stick with the blue ones for deburring and only use the maroon ones for deep machining marks. The white ones are overkill for deburring but probably great for fine blending before polishing.

Time: 1 hour
