Other Massey users, do you ever have a problem with the oil dipstick and a bunch of oil being blown out when using the single blow/squeeze setting? The previous users of my hammer started the hammer in low pressure hold up and I have always done the same as going from hold down to low pressure hold up the dipstick gets blown out. As well the treadle guard on the hammer interferes with the treadle going all the way up which is not a problem at all when using the hammer with the treadle. As the handles are on the opposite side of the hammer I am not sure exactly when the oil blows out but I suspect it is during the high pressure hold down.
I am ordering a plate burnout today to make a new treadle guard as I had to extend the treadle last week so I could run the hammer from the back side. I had to forge a bunch of 12' long chisel bars and it was either punch a hole in the wall (which I considered) or run them through from the back on a 45. My dies are 9"x3.5" so I could not run them on the ends of the dies. I am also ordering steel for new 8" square dies this week so I can run them on the other side from the front. They are going to take a while to machine though I will probably have to run the bars through from the back again.
