Wing rib deburring
Hours: 2.8 | Posted in Spars & SkeletonSpent the evening decompressing in the shop and deburred some wing ribs. Finished all the lightening holes with assorted 1″ and 2″ scotchbrite wheels in the drill press and die grinder. Finished the leading edge ribs (non-tank) with the bench grinder and the 6″ wheel. I used a handy tip I read from another builder about deburring the silly little finger notches — take a section of worn-out 1″ wheel and cut it into quarters, put a piece onto a Dremel screw mandrel, and shape it into a cone against the 6″ wheel on the grinder. This creates a custom tiny scotchbrite tool for the Dremel–it actually works quite nicely, though the tiny piece wears down after a half-dozen ribs or so, and needs to be replaced. No biggie, as I have two worn-out 1″ wheels. More on order from Cleaveland to replace them, along with a bundle of hand pads for primer prep, a #12 bit (I discovered that the #12 slot in my bit set actually held a #11). I also ordered a batch of Stewart Systems priming supplies from RFS.
Allison helped for an hour deburring ribs on the bench grinder.
