    Would changing the steel line and fittings to the size of the ports on both the cylinder and valve help with cycle time? The 90° fitting on both currently drop down in size on valve to line and on cylinder to line.

    I’m not the expert, my friend is. From what I understand about my splitter is the speed comes from a higher hp engine and smaller cylinder. The pump has and adjustment screw where you can increase the pressure before your 2nd stage engages. Stays in faster 1st stage longer, conserves fuel, easier on engine. The downside is the engine may stall before 2nd stage kicks in.

    I put in a call to my buddy about your specific question. I’ll post up an answer when I hear back from him.

    I got some info for you. The log splitter builder says it depends on the orifice sizes on the cylinder.
    The metal line on your machine looks smaller, so it’s worth a try. Looks like you could change those fittings on the cylinder to accept a bigger line. Yes more flow means faster, but you can’t run 10gpm through an 8gpm hole. See what I’m saying. If your hose is flowing more than the hole can accept it won’t change much. He said you can take the cylinder apart and mill the holes out bigger, or get a cylinder with bigger orifices. Hope that helps.

    Well...it just so happens, I might be able to do something about that. I have a boring tower as well.

    I'd take the line and fittings off and have a look at the size of the hole into the cylinder...if it is the same or larger diameter than the steel line ID, then I would say you stand to gain some speed by upsizing the line/fittings...and if you could figure a way to eliminate those hard 90* turns, that would help a bit...and help lower the oil operating temp a bit too...

    I was thinking hose with fittings and allow for a gentle sweep at the connections.
