I may have a need to remove some rivets (20-30) and was wondering if anyone can offer advice on how to do so without screwing up the finished structure.



Thanks in advance!

You should use a pin punch to drive out the rivet stem and then use  

the proper size drill (1/8" for A4, 5/32" for A5) to drill just deep  

enough to remove the rivet head. It's pretty easy to remove the rivets  

this way without damaging the hole.

As an expert in the field of rivet removal  .  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.

All-

    Having had to remove hundreds of rivets, here's my technique-

    1. 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.

                                                                Bill
