Glad to hear this is working for you. Some of the red oak I burn will
definitely resist my 3-1/2" splitter at 2500PSI and needs to be cut
with a chainsaw.

The two-stage bypass in my hydraulic pump is a spring-loaded ball
valve that opens at about 600PSI. The pump wasn't too bad to open up
and work on when I replaced a bearing. I suggest having someone else
with clean hands photograph it during disassembly so you can
reassemble the pieces in the correct order.

I recently watched Jewel on Soundstage and was very impressed. Looking
her up lead to Ty Murray and his ranch in Stephenville and how much he
likes that part of north central Texas. Are you anywhere nearby?
