[Wing] Deburring Question

[Jim Oke]

Hi Tedd,

All I did was use a very thin flat file to get the worst of the chips from
drilling the hole off. Then some scotchbrite to generally smooth things
over. Not a true "countersunk" deburr, but more of a "best available"
solution.

Try Cdn Tire or Princess Auto for a "needle" file set. A few dollars for a
set of 6 or 8 small files. Handy for doing odd corners and angles throughout
the project.

One tip, use fluting pliers or similar to open up the rib flange to get your
dimpling set or whatever in place, dimple to taste, then re-bend the flange
to 90 deg.

Also if the skin holes are not drilled as yet, try and offset the top &
bottom surface holes towards the aft end of the rib by 3/16 - 1/4 in or so.
This will be a help when it comes time to try and rivet in this area. A
Princess Auto "splitting wedge", normally used for chopping up logs for your
fireplace, is a reasonable substitute for a normal bucking bar in this area
too. The pop rivet route is another way to go.
