  1. In fact my cilinder is quite hard to move by hand, but I opened to clean, because it is very old, and it didn’t had any sign of oil inside, so I assume it is pneumatic.. about the ram, I’ve mande a nylon bushing inside a steel tube, to work as guide.. the ram runs easily inside the guide, I’ve made it with 0,1cm difference and added a lot of solid Vaseline to lubricate the ram.. one thing that may be slowing it down is in the air inlet.. Im using a 1/4” hose connected to a 1/4” air outlet, because it’s the only one that is long enough to reach the hammer..
  2. That’s basically what I did.. the video I’ve posted shows how it’s aranged, I don’t know if you can see now, here it seems to be ok.. the only thing that is different is the port 1 connections.. I’ve added a check valve before connecting to the pilot valve. The ball valve at the end of the circuit is exactly like this but I forgot to record it
  3. Hello everyone! My name is Andre, I’m naturally from Brazil.  I am finishing my kynion style pneumatic hammer but I’m having a low bpm problem and I don’t know what is the main cause, since I have a 250L compressor running with 15bar.. this is the compressor. My piston is kinda big, but I don’t think that it would be a problem to this compressor... it have 115mm on its base, and the arm diameter is 45mm ( don’t know if this is the right word). The length of the closed piston is 85cm and opened is 145cm. to create the air circuit I’ve based myself on crickets air
