Last week we had a big storm up north here. Elderly neighbors had trees blow down that had been there since Christ was a child. I went over and cut them up and about the time I finished they came out with wood spitter. I just got done with all that and thought that I had a 90 lb piece of Mary Ellen I needed to resize to fit my smaller saw. So I ran home threw her in the truck and came back. You should have seen the look on their face when I threw Mary Ellen on the rack and held her down. Told'im to hit the lever and wallah now I have two pieces Mary and Ellen. jamesp would have been proud. So to make a long story longer. When I was younger I wanted a laboratory size rock crusher and everytime I had found one for sale it was gone about an hour before I got there. So here is my idea ...square metal box (heavy steel) maybe the bottome welded criss cross with hardened rod to help the break up. Plate that fit into box attached to an adjustable throw hydaulic cylinder. Manual or hrydraulic. I think it would be like magic, no flying pieces when you wack them with a hammer. Maybe one day I will tell the story of the hydraulic oil filter crusher.

nowyo uses a hydraulic press to split rocks. I have not seen it in action but if I remember right he has a wedge point on top and just a flat plate on the bottom. More splitting than crushing action like you did with the log splitter. Maybe he will come on and give a better explanation. Jim

Might not be hydraulic but here is a photo of the rock crusher that is used for all the rough that gets sent out for the Feather River Lapidary tumbling contest. Neat look piece of machinery. Rocks go in the hopper up top and come out the chute at the rear.

Looks like a gold ore crusher with a hit n miss engine. That's a antique for sure, is it a hammer mill or roller mill?

Explains why my rough this year looked like it had been run over with a steam roller

Dynamite maybe? If the use exploses it fractures to the core! Even huge boulders will b full of fractures. That's why Larry uses trachea to mine his Willow Creek claim. It's slow going thru solid rock but what you pull out is much better quality. He pulls out Volkswagon sized t eggs and then jackhammer them open and might only get a very small but beautif u center or gets nothing sometimes. It's a wonderful material tho.

There is wedge and feathers? or you could try drilling holes then use some kind of expansion material-agent. That is a 4 foot drill bit I am about to use in the pic. Good results when holes are spaced a foot apart. www.miconproducts.com/wedges.html
