Just discovered a easy and disposable blind hole deburring tool. You're
walking on them.
Take a steel rivet mandrel and grind a edge on one side for about 1/4". Sort
of like a short blunt knife blade. Then bend about 3/16" of this sharpened
part up toward the rest of the shaft (less than 90 degrees). Put a paint
spot on the shaft so you know which way the bend is facing when its in the
hole. Now chuck it in a slow cordless drill and insert it in the hole to be
deburred by starting at an angle and then straightening out. Spin the drill
and then pull up gently. Practice on scrap before you use it on your spar.
My first one worked great.
