I have used my Marson hand 39000 Hp2 rivet gun for the past 24 years at work and it is still going strong. They have other modals and are sold by many stores. If you do not want to spend the money do not test a pneumatic riveting tool. Last year the arthritis kicked in and after pulling 3 3/16 steel rivets I borrowed a pneumatic for the last 13. It was great.

If you have the money go pneumatic. If not by a good hand rivet tool and not a cheap one. They do a better job then the cheap ones and last longer.
