I don't have enough details drawn up in SW yet to check the mass properties but I know it will be tongue heavy. I have a couple of Briggs engines in SW but not the one I'm using but I could fake that by weighing the one I have.

Thanks

Yea you don't need perfect numbers. Just look up specs on line and put a block where the engine goes that weighs similar.
 
I assume the pressure gauge T's into the work line somewhere convenient like near the detent valve, but what pressure range do you use 0-3000 or 0-3600 or 0-4000?

How do you cipher the tank capacity?

Here is where I'm at today on the design side... the only thing set in stone (built) at this point is the axle and springs and the beam.

A good rule of thumb most guys here go by is a gallon of oil per gpm on your pump. So if you have a 13gpm pump 13 gallons of oil. Keep in mind your lines, valves, and cylinder hold a lot too.

However, this is more for industrial use! Looking at store bought splitters they have way less oil capacity.
 
I can fit a 12 gallon tank in the frame now and the cylinder holds 1 to 1.25 gallons so if I put 10 gallons in there that gives me 3 to 3.25 gallons of head space in the tank... I think it will work. Mind you I'm not the fastest splitter in the west or mid-west as the case may be and I take frequent naps just for good measure.

Thanks,

I just got the hydraulic tank fittings, suction strainer, return filter and vent cap today... the order status for the cylinder changed from back ordered to pending so that is a good sign.

Unfortunately I will get side tracked for a bit on the splitter as I have two automatics to build now.

Status update on the cylinder, shipped! I dug around and found some castors with 250x4 tires for the front wheels. I have a few more ideas floating around in my head... the tongue will pivot up for storage and the castors will permit easy parking when not in use.

That sure don't look like torch and sledgehammer metal forming. What'd you use to bend it?

One each of these...

Nice. I'm spoiled. Where I work we have brake presses up to 350 tons. Sometimes I can con em into a "government project". Otherwise, I use the aforementioned torch & sledge method if it needs fixed NOW.

My torch set is a weak link in my tool chain for sure and the tiny rosebud I have will hardly get 1/4" thick cherry red. So the press is my go to tool for bending.

Some progress on the beam tonight...

Lion cylinder showed up :) The thread size is listed as 3/4-16 which seems to be an o-ring fitting... the fittings might be fun to track down.

I have some 1" steel showing up tomorrow with some steel for some machines, I decided to order a 12" x 18" x 1" piece for the reaction plate and a 12" x 12" x 1" piece for the wedge and clevis...
