Where are the tonnage specs coming from ?

[sundance]

I have a TSC Countryline 25T I picked up on sale for $900. It has split everything I've put in it, 23" ash rounds included.

I don't think anyone questions the ability of splitters, just the outlandish tonnage claims makers put on them.

Cord King?
Seems like it used a 6" or 7" cylinder if memory serves me.

7" cylinder at 3000psi makes about 55 tons of force.

Yes sir. I think it was rated at 58 tons. As it was made in Canada, you probably need to discount tonnage by 33%.

It’s pi time (x) the bore, times (x) the hydraulic pressure.

The surplus center has the hydraulic pumps and cylinders you match the pump to your engines hp.

My last homebuilt splitter was a 5” bore x pi 3.1416= 15.07 x 3,000 psi= 47.124 tons. What she didn’t split she cut through it.

I built a 32ton splitter with a 3,000psi with a 3.5” bore cylinder for 25 years homemade. My only problems was the free I beam was too thin but a sledge hammer would fix it when it bent but not often.

I have extra I beams here is anyone in ct or nearby is interested affordable.

Um ya, your math's a bit off there.

This is how i did pressure calculations for boiler examination.

Easy way to remember is that a circle is 79% (.7854) of a square. 5” square =25sq.in.

79% of 25 = 19.75 sq in area times force.

19.75 x 3000psi = 59,250 pounds force.

Convert to tons 59,250/2000= 29.625 (tons)

When I bought my house with old woodstove(since upgraded), I started cutting my own firewood and bought a small, electric 4 ton splitter. It is an awesome machine and has split over 50 cords of wood.
surprising what it could do. I use it to do small amounts or kindling or indoor splitting now.
I've since bought a Forest King farm model hydro splitter rated at 30 tons.
I know it can't be pushing 30 tons of force at the blade so its definitely false advertising.
It does good though and was on sale so I'm happy with it.

Man I have had the same electric one..it was horrible. Wedge design too blunt. Granted didn't have much in it and made a few bucks off it.

Did just pick up a 30 ton Brute that is about identical to yours too. It is a lot faster and a lot more power than my homebuilt one. Smaller pump and cylinder are culprit i think. Nice splitter tho!!!

Tonnage only equates to part of the equation too.

A sharp, thin knife will split wood with much less force required than a dull wedge that's wide.

SO Many times I get asked if I put a bigger engine on my existing splitter will it cycle faster? No. More speed requires a larger flow, which then takes more horsepower to turn that larger pump at the same maximum pressure.

Thats actually a yes and no answer. I have never tested this, but observation has led me to believe that most box store splitters are supplied with just enough engine to run at full load without stalling. In this situation the motor will slow rpms as the pump pressure increases. This is the point where a little more hp will decrease cycle times due to the ability to maintain rpms and pump flow. Now how much this small amount of rpm and flow will decrease cycle times isnt as important as is that little extra "speed" worth the cost. While the cost of a 1 or 2 hp bigger engine is a small, one time, cost, the every day cost would have to include the extra fuel needed every day the machine is operated. Or in my case is the faster cycle time worth more to me than being aggravated waiting on the cylinder to return. My splitter is way over powered with a 25 hp kholer and 28gmp 2 stage pump and I wouldnt want to swap the motor out for a smaller one even tho the math says I can.

I would be more impressed if you said a 23" elm or oak crotch. It does not matter what dia the wood is if it is straight. I have done 43 " pine rounds. Does that indicate that I have a super splitter----no.
