I will state that on thinner gage material i.e. .032 or less in thickness, using a pin punch is a good first try. Do so lightly. If it doesn't budge (I knock it swiftly but not too aggressively as to bend the material), then I move on to a good set of needle nose pliers using more of a rolling motion. You can also back the pliers (roll against a piece of scrap). Haven't found one yet that I couldn't get out without damaging or otherwise elongating the hol. Word of advice: Pay attention when your are drilling out a rivet, if you aren't careful, it can walk (especially ones where the stem is a little higher up) it may push your bit one direction or another, then you have a figure 8 shaped hole. -------- One Rivet at a Time!

I really like it and it works very well. I only fly VFR and my data base is about 2001 (front panel removable data card). If anyone has replaced their 150XL or 250XL data card, I would interested in a more recent data card than I now have. Chuck D.

Start with a large, 3/16-1/4" BLUNT drill chucked into a variable speed drill set at low speed. I don't think you can do this with an air drill, and you don't want a sharp drill or you'll go right through. 2. On slow speed, drill about 1/2 the way down the rivet. If the head hasn't come off by now, give a couple of bursts while juking the bit with down pressure. 3. If the head still hasn't come off, use a cold chisel to knock it off. 4. Drill the mandrel out with a #40 bit, then increase bit size to one smaller than the finished diameter. Pull the remainder out with a good sized set of side cutting pliers. Rivet removal is an inexact science with everything changing from one to another. Some will come right out, and some are a PIA. Good luck.
