And yet another log splitter build

[bob is your uncle]

Well, decided to build a splitter as i couldn't find any of the lower priced ones liked. the main beam is a W14X61 the oil tank is double 6X6HSS holding about 80 liters of oil, the motor is a old 19hp briggs opposed twin with a 22GPM two stage pump, the cylinder is approximately 5" bore off of some sort of cat NOS from the scrapper. if i did it again I'd definitely do it different its very tongue heavy but it does allow you to pull it from the pile of splits rather than burying your own hitch. Still need to find a way to slow the log lift down. (sorry don't know how to resize these)

GREAT JOB!! Such a great looking splitter. I bet you it will tear it!

Nice looking splitter,,
The suction, and return need to be near the center of the length of the oil tank.
(as well as the fill, which, I think already is near the center?)
If the suction and return stay at the ends, you will at different times, get foaming of the oil, and starvation of the pump.

Both will damage the pump.

While you are moving those, might as well move the axle towards the middle, so that you do not have to fight all that weight to move the splitter when it is not hooked to the truck.

I think your video is set to "private",, possibly.

hold on, will try to fix the video first time using youtube.

it got build and modified over two years the axle ended up in the back since if it was nearer the middle it would either be where the pump is or where I'd want to stand (had a vertical shaft engine so had to mount vertically making quite the tall stack up).

Yes, the return is on the back in the center of the two tubes and the suction near the front, guess ill live with it and see how that works out i should have put the fill caps on risers so it doesn't splooge fluid so easily.

my intent is to split with it hooked up so i can keep pulling it out of the pile.

how does this cause the foaming and how would putting them near the center mitigate this?

To slow down the lift...
I forget the term, but they make a little insert that restricts flow. I believe it's placed in the end of a hyd line.
Nice build

It is called a "blind fitting" , it is male, female about an inch long, with no hole in the middle, hence, "blind".
You get to drill the hole size that allows the amount of flow desired,,

Start with a 0.060" drill, if too slow, use the next larger drill,, and try again,,

Visualize where the oil is if the wedge end of the splitter is "low"
Now,,
visualize where the oil is if the wedge end is "high"

If operated connected to the truck, the low or high is what you will be seeing as operating conditions.
(very few places offer flat land,, perfectly flat)

You mentioned the oil "splooging" out of the fill,,
I would bet that was when the wedge end is "high",, right??

The pump and return were foaming the oil, the oil expanded because it was full of air,,
there was no where for the oil to go in the now pressurized tank,,
out the fill was where the oil had to go,,
