Valve for log splitter

[hoff135]

Me and a mate are building a log splitter which is going to be pretty powerful hopefully. Ram is 4 inches in diameter and planning a 4 or six way head.

My mf 6480 pumps 110lpm with load sensing.

There are numerous valves on the internet, a lot are only rated at 80 or 90lpm. Would this be a problem?

Also do i need a relief valve?

Looking for auto kickout on the return too. Also how big should hose be?

Any info appreciated

Thanks

The kick out on the flowfit tends to destroy itself as the spring is too strong imo. It's fine and the valve works but the levers loosens, rattles and shears off.

Here you go, I’ve used these on the dozen or so I’ve made. They’re warranted for 12 months anyway so use to death and if it breaks get a new one.

you can just make an adjustable return stop if you don’t want it returning all the way to the top

Be very very sure it’s only you and your mate using it and not staff legally they have to have two hand operation etc as they’re a high pressure Press.

when your making your splitting wedge I find a stepped splitting tool helps break wood wider and Easier.

use a regeneration valve on the ram if you want faster cycle times, sends oil out the rod side back in to the piston side, until its got pressure on it then it closes off and goes normal speed, once log is cracked it will speed up again to push it through. Might not be a problem for logs but its very good on a trunk splitter

Max 80 litres per minute

From a few quick, rough calculations your 110ltrs - if all of it can get to the cylinder and out quick enough, it will stroke your cylinder out in less than 3 secs and so will return even quicker.
Mind your fingers at that rate

 

[fiatf130]

Surely 110 lpm is at tractor rated speed so unless you are revving the tractor to rated speed it will be less than that?

 

[Mur Huwcun]

You will never get 80lpm out of a 1/2 QRC coupling on tractor anyhow plus the tractor would need a few revs to achieve 80. If you stick a flow meter on tractor I would hazard a guess that you'll be around max 50lpm just above idle speed

The noise from anywhere near that flow of oil through that valve type will do you're head in after about 30 secs. I know this from running log splitter off 8 ton digger hammer line. Ended up turning flow down to about 15 litres a min was still plenty fast enough. Mine's not a big ram mind but even so do you know you need that amount of flow?

 

[hoff135]

Yeah i guess you guys are right 110 will be flat out and that wont be happening.

Ill probably end up using it one the 3075 which has less flow. Or i can turn the flow down on the spools on the 6480.

I just didnt want to end up heating the oil

Just needs a paint and hoses-
Thought someone might be interested

Rams only 3 and half i think. Hope its big enough everything else is over engineered

used several log splitters on same 110lt masseys & you dont even need that much its set lower am sure either on electric spool or manual always turned back from full flow & about 1050/1100 revs is far plenty enuff. its not so much the fast flow it just needs a constant supply of oil
ran horizontal splitters like one above all home made & 3 diff verticals since.
The output of the RAM is the thing that will stop when it meets its wood mass thats it.

Looks good ,have you a loader to lift the tree onto it ,nice log lifting arm ,next addition ?
and pleased to see your workshop a bit like ours , ,dont move any thingnor you cannot find it ,
you must have a lot of wind up there if need that big a rope to anchor that christmas tree

 

[Farma Parma]

i have a bought 14t rated vertical splitter here now & it has its limits i can assure you.
i think the likes of a ram on a 50t press is the answer for stubourn timber but you would end up with injuries when i piece flies outwards thats the trouble

Built a much inferior splitter to yours once...similar design.
Lifting logs onto it is always a problem...but I found that having the ram etc at sort of bench / table height easier in the long run.
Working bent over for an hour or two gets to be tedious. After all not all of the logs will be trunk size.
No doubt the power of the ram will help, but the horizontal blades will end up with logs stuck under them, between the RSJ and the blade.
Increases the risk of a really bad splitter becoming stuck on the blade.....sledge hammer required to batter it back off.
As has been mentioned parts of logs from difficult splitters...knotty twisted grain etc can depart the scene at high speed.
Either no one allowed in the vicinity or something to stop them flying.
Is the long stroke for a particular reason....? A stove that takes logs that length..?
True enough long logs speed up the splitting time....but not if they are to saw into shorter lengths.

Admire your fabrication skills.

blade that the log is pushed to split it is far better if it has a pointed bit to start the wood splitting as against more of a blade once started no problem

Its heavy but its what was available a long with the ram.

Its a case of trial and error if the wings on thw blade are a pest ill cut them off. Also was intending sitting the splitter up on blocks for extra height.

Ive rounds that are nearly 3ft in diameter to split which i loaded on a trailer by hand already haha. Failing that i have the mini digger with the bucket and thumb.

Ill post more posts when i get it working. Thanks for the input though

Quite agree.....length of blade causes a huge build up of pressure with a difficult to split log.
Something to get you going then begin to split wider.
I had the same problem with the length of ram, it’s whats available, not always the ideal thing.

The wings need to be angled forward slightly.

Also no ware near enough angle on the cutting edge, but you did right only putting cutting edge on the top side of wings, stops logs jamming under wing.
Also good to let the blade float up if needed.
