Could you go into some detail on your electric splitter? I've never heard of anyone using a 4-way wedge on an electric splitter before.
It used to be gas powered, but the motor finally wore out so I replaced it with a 3hp 240v single phase electric. It is 20+ ton and costs about 15 cents an hour to run. No vibration, no loud gas motor, no pull starting in the cold, no fumes, no oil, just relatively quiet splitting.
This is a 3600 rpm motor to get full flow from my pump, but Iwould prefer to use a 1725 rpm motor and a 2× bigger pump to get the same flow with less pump noise. The motor is near dead quiet, it's the pump that whines. They make lobed pumps now, but I already had this pump and only had about $100 to spend, so I used it. It's 11.x gpm to start and drops to 1.8 gpm for high pressure.
The 4 way is removeable for tougher pieces, but I have only had to remove it 2-3 times. I am going to build a chute to get the wood out in front of the splitter more.
