Which Log Splitter?

[Lightspeed]

Next investment in the wood store is probably going to be a log splitter.

I need advice.

Logs I need to split will mainly be fresh felled spruce, 4 -5ft long and 12" to 30" diameter.

To power it I have 240v 16a into the woodstore now, although I'd really only be happy drawing 10a on that circuit = 2.5Kw max

On the other hand we have 3 phase outlets in the barn at the other end of the house and could conceivably split there and transport output to the wood store. This would be a considerable additional expenditure of effort. Otherwise it would mean running 40ft of cable from barn to wood store. This may be economically viable, in terms of human energy saving, especially if there are advantages to be had running a circular saw from 3 phase.

I think the questions I really need answering are:

* how many tons pressure are required?
* Single phase or three phase?
* What benefit vertical vs horizontal operation?
* any other features I need to look out for?
