It’s quite cold out today (-17C) but I managed to get the garage up to 10. I deburred some more ribs today. I think I finally have it figured out. I’m using a deburring tool for the large lightening holes then a scotch brite pad to finish the holes. Next I use the scotch brite wheel in the grinder for the edges of the rib. It does a wonderful and quick job. Finally, a scotch brite pad just to finish things up. 7 ribs completely deburred, 19 more to go.
Welcome to my builders log for Sonex S/N 767. It won't be as big as a real 767 but if you scale the speed I bet it will be almost as fast
