I blew up one of thre buffs the other day and needed to pull the cylinders, no pull plate (I had given it away a long time ago) so I fired up the cmm and the haas and rolled out 5 plates. they are 1/2" thick and I used m10 1.5mm for the pulling bolts. I will make these avail to board members at a nominal cost so pm me if in need. I also have 2 plates 3/4" thick If you have a very stubborn old girl. (you have to supply the hardware I suggest http://www.mcmaster.com/#99067a251/=eejaxd" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false; ) and some nuts to match just jam them together with red loctite. The screws have to be about 110-120mm long)
