Drilling out a smiley
 
One technique that has worked for me is to drill all the way through from the shop head with a small (#50) drill. You should come out the other end near the center.

Now, use the small hole to guide a #30 drill and drill deep enough to snap off the head. You can then either punch the rivet out or, better still, use a pair of dykes to work it out from the other end.

Jim, how did the rivet extraction go?

Hey Tom,

Just got off work today (I work 12 hour shifts 7 days on 7 days off). I have the skins on to match drill and CS. Hoping to have it worked out by Thursday. I will definitely let you all know how it went.

I tried using a cutting wheel to grind off he manufactured head. It was impossible to get to without bumping into the rib or flanges so I put my big boy pants on and decided to give drilling the shop head a try again. I'm happy to say I got it out without any damage to the hole or doubler.

Thanks for the help all.

Nice work.

I have some tiny ball ended carbide burrs from my dremel. I picked them up at OSH a few years back, but after need one, it would be worth full price.

The tiny little unit is much easier to keep under control in tight quarters.

Again - nicely done.
