Thanks for your kind words, I too think these hammers have a great interest to anyone who has run one. It's interesting to me the different traits throughout the different hammers and personalities within the same models. I have run a few different type and size hammers but have never been drawn to the switch type air hammers, I think it was due to the rhythm (well maybe the size as well) Anyone who has ever been around a Nazel, Chambersburg or Massey will contest there is nothing like it, well maybe an old Harley, hit miss engine or steam locomotive. To me it's about the rhythm & vibration, their function BAM BAM BAM!
