  1. I realize that this is obvious and you are probably set on operating 3 phase but it occurs to me that if this was the only 3 ph equipment in my shop and my power was limited to single phase, I would just buy a 15hp single phase motor with suitable pulleys to produce desired speed and forget fooling with phase converters or the cost of adding 3 phase power to the shop. No? Here's a 10hp single phase compressor duty 1750rpm from Northern Tools for $850 http://www.northerntool.com/shop/tools/product_200381915_200381915 (you might not get much more than 10hp from a 3ph 15hp running
  2. Here are pics of the roller control valve and the main slide valve. You can see the homemade body of the actuator for the roller control valve that I fabricated to replace the crappy broken plastic one that it came with. I'll bet that is what happened to yours and the owner just took a different tach to solve the problem. Let me know if you need more detailed pics of this assembly and I'll take some more.
  3. Yes, I'm using all 3/4" fittings, since that keeps the airway equal to or above 1/2" everywhere. This is emphasized in the operator instructions. When I first got my hammer (in 2003) it was having a problem with the control valve and after much back and forth with Bullhammer, they sent a replacement, which was from an earlier design. It seems mine was a new style they had newly incorporated, but it wasn't doing the job for me. It wasn't too long after I installed the replacement that it's plastic actuator housing cracked and I really didn't want to deal with their customer service again.

  5. Congrats! That's a fine hammer, though I can't say much for their customer service. I bought mine new, probably 10 years ago now. 1) Oil should be supplied by continuous mist, not heavier than SAE 10W non-detergent motor oil, no additives, no synthetics, not anything but straight oil. 2) The hammer comes from the factory set to work best at 140-150psi needing 15-30cfm. Also, very important that you have at least 1/2" line and 3/4" fittings from your compressor because this baby gulps lots of air in bursts of over 100cfm. In fact, what I did to make it perform better was put a 10
