I understand now how the pump attaches to it.Thanks Steve, The motor is sort of a standard one here. 2.2KW with feet and flange used all over for pumps (water). Just trying to find the best one at the best price  But I don't want to go too cheap and have it fall to bits after a few months.   DaveH

On the control valve - anyone know why it is so big compared to some others I have seen?
Also next to orange plugs there are two more 'ports' with two silver coloured plugs, anyone know what they are for? DaveH

My guess is that "lots of things" want a larger valve and flow rate than a log splitter and then the follow on is that a generic valve that fits "lots of things" is cheaper to make based on economy of scale than a smaller one. Other than the cumbersome nature of the valve it should not affect your performance.

Again a guess on my part but it could be where you would insert plugs to convert the valve from open center to closed center or for power-beyond fittings. Arvid

Thanks Arvid,
I couldn't find anyone/company that sold "log splitter" control valves as such. So I had to take what I could get. I understand 'closed centre open centre' and I have seen in my travels around the internet about hydraulics/control valves the term 'power beyond fittings' - I thought it was something to do with the "trekkies"  DaveH

Got some more goodies today
2.2KW motor. Shown here with the bellhousing just pushed on. "But wait ............ there's more" DaveH
Originally I was getting a single phase cap. start/ cap. run motor which are expensive. So while at the 'motor shop' I decided to look for a motor for my lathe a 1.5KW, same thing cap.start and run.
They showed me this 'plug and play' inverter system - the inverter I can just plug into the wall socket and then just plug in the motor. Fully portable interchangeable. The real big advantage is the cost of a 3 phase 2.2KW motor compared to a single phase 2.2KW motor. In my case it costs a third of a single phase motor. So I ended up with a 3 phase 2.2KW motor and an inverter and not much more than just a single phase motor. Two 3 phase motors plus an inverter cost less than two single phase motors. The control part of the inverter can be used remotely. DaveH
Finishing off the design - well more like where to put this
Being in the Southern hemisphere can lead to a few problems - like the motor goes the wrong way, simple fix mount it upside down. I think this is going to be the most expensive log splitter in the world  DaveH

Ed,
It is a 3 phase motor 220/380v, the inverter comes with a 100 page 'operation manual' looks to me it as it was written by a space man  DaveH

I had the same problem when I first installed a 3-phase motor and VFD on my mill. I wondered why the hole I was trying to drill was taking so long until I realized the spindle was turning in the wrong direction. I swapped two of the wires on the motor and all was well.
