I came across some huge cylinders 7"x20 and 7"x24 w/ 2.5" rods and would like to build a Wallenstein type splitter. Ihave a few questions you guys might be able to answer. With the cylinder welded in place, how would someone repair or re-pack it if there is a problem? Could the splitting wedge at the end of the beam be made removable and stay strong enough? Any ideas for making the wedge and pusher interchangeable? I want to use it horizontially with the wedge at the far end and vertically with the wedge on the cylinder. Anyone with a Wallenstein or who has built one similar, please post your ideas.
