Hi Everybody, I wanted to introduce a new tool that is perfect for the RV12. Milwaukee has a new electric pop-rivet tool #2550-20. It is about $170, a bit expensive over the $35 harbor freight air tool. It rocks. It is a bit heavy, but it has fits in the hand great, lasts forever. Only issue, make sure you drop those shafts in the collector after every rivet or you will get a jam. Overall very happy.
