So you're saying that you don't drill the rivets partially and then chisel the heads off? I have a nice IR air chisel I'm using but if I want to reuse the holes to install new rivets straight chiseling the rivet heads turns a nice round hole into an oval or obround hole. Please clarify if you would[emoji15]

None of the thousands of rivet holes on my bus went oblong from air chiseling.
But do it whatever way you see fit.
I agree with bob- drive out the mandrels with a pointy bit, then shear the heads right off those pesky rivets. Not that I've got it down to system I can de-rivet a while 40' bus interior in about 3 hours.
