I'm thinking that a small industrial forklift axle might just be the ticket. Narrow and I would imagine, very stout.
Shinn, I sent you a PM about a swap if interested.

Forklift axle is pre narrowed I suppose, I wonder if open diff, but probably yes.  Of course if I go to a junk forklift place ill probably end up with the piston and if I swap you for a pump this is a mute thread at this point, but I am intrigued.

I also don't imagine it needs to be more than a car axle.  27 PTO horses going thru a setup designed for 120 plus and it should be fine.  Having seen how a differential works and is constructed, I don't see any problem running one side consistently more than the other if it is a decent axle in the first place and the fact they live in 90 wt oil makes me feel even better.  I am debating wether I want to deal with drum brakes or disc.  the drum gives the option of a simpler cable emergency brake operation were the disc would require a master cylinder and do any cars today have unboosted units?  Would a clutch slave cylinder work?

If you can build that contraption, might as well build a proper one with a hydraulic pump. We had one built home made locally including the old snow blower engine for around $500, has a hitch and wheels and back leg to. Heavier and cheaper than ones in the box stores. ;D

That vid sure answers a lot of questions about the potential for the OP's idea.

Looks like a nice setup, and think he mentioned it uses a 1/2" cable. But running slower than the OP plan, or not?

Great find on that video.   That's the one I had seen a few years back, but couldn't find it recently.    As for speed, the big advantage I see is the cycle back.   Some decent garage door springs or a counterweight could make that pretty quick.   He mentioned how he geared it so any tractor could spin it and obviously the engine wasn't revving very high, so it could be faster but for safety that seemed about right.  That said, using a transmission AND pulleys with the 3/4 ton axle does speak to the gear reduction that will be needed. 

Another intriguing aspect is using the opposite wheel as a winch as he does, but it could also be made into a shear or chunker for the smaller stuff. 

Wheels turning in my mind anyway....

That's the one I could not find!

Thanks r.man, I wanted to watch it again.

This guy uses an axle setup with supersplit parts and the other side is a chunker shear.

Wow, I don't consider myself a safety freak but that guys fingertips and or fingers are not long for this world if he doesn't change his habits. I am not a huge believer in over-guarding but that machine needs something to keep his fingers back from the chunker and he needs a table so he will let go of the blocks being split.

Agree with you on that guys safety setup but It showed it is possible.  In researching  this  on line,  There are lots of guys  that take a 2 speed rear and spin it with a tire driven by a pipe welded to a small engine.  I think I might try that first as a power  source.   One of those  chunker guys stuck a large propane cylinder over the whole thing and made it much safer.  Unless I get into the smoker/charcoal/gasifier biz, I don't want to chunk but see it as a way to quickly cut up smaller branches.  I would mount a standard rim on it as well to use it as a capstan for bigger blocks of wood.

There are european machines that do the same as the chunker but also use a 90 degree piece on the cutting wheel that splittes the chunked piece as it cuts it. They are used for branchwood and polewood and look to be fast and low maintenance.

Those euro chunkers are slick, I seen a few tube clips of some that fed the stick in from the top so that gravity does the work for you once you get the stick in. I think one was mounted on a excavator boom.
 
Now if a person needed a heavy flywheel could you fill a tire with fluid, and would it self balance once spinning?

If the tire would balance it self as it is turning by the fluid going to he outer part of the inside of the tire evenly.

Might depend.

Likely the fluid would just sit in the tire and not spin with it at lower rpm, but at some point the friction may increase as the rpm of the tire picks up. However, before centrifugal force  could move the fluid out to the outer part evenly, there likely would be a very unstable rpm that would throw things out of kilter.

Such happens with tractor tires that have fluid in them. People have experienced the unstable effects of the fluid when the speed of the tractor (such as if coasting down a hill fast) reaches the point that the fluid starts moving around and over the top inside the tire. If that makes sense, there have been some bad accidents as a result.

I see what you are saying, that in between speed before it gets balanced could be quite scary.

a guy here used a transmission off a tiller to build a winch loader for a pulp wood truck. he had two forward speeds and one reverse speed. people have also used the limited slip rear ends for loaders on the same trucks.
the tiller loader would pick up the world if you could hook it up. he pulled the truck out of the mud before with it.

Why would you want a chunkier? And have to fool with all the little pieces.
Do you shovel the stuff in the wood stove?

I'm guessing the chunks are mostly getting used for gasifier boilers. Those stoves like low moisture content and the chunking would get em drier.

Storing them seems like a pain though.
