hey guys !! im new here, just joined today and want to say thanks for allowing me to join!!! i have plans to build a power hammer from a 3116 caterpiller engine block and crankshaft. what do yall think ?

Engine blocks have a lot of open space lowering the efficiency. If you have access to a Cat what about using an axle or other large SOLID chunk of steel for the anvil?

I take it this is going to be a tool that does not get hauled around! :D :D

Sounds an interesting build .May the bluebird of uncomplicated sucsess make it's home there!

Not the best of both as concrete and engine have different vibration profiles and so the bond is not usually a good one over time. Using a big hunk of solid steel is the best way to go and if you have access to a Cat you should have the steel too!

Note that the density of steel is approx 3 times that of concrete so lots of concrete doesn't give you much extra mass.

Welcome aboard Mongo, glad to have ya!

As Thomas says concrete isn't a good choice, it'll debond and pulverize a couple thousandths at a time. Do you have a set of plans or are you designing the hammer yourself? Post some drawings and we'll be able to make better suggestions and spot things that are unlikely to work.

I think using the crankshaft as the eccentric is a good idea, but eliminating the engine block or at least turning it upside down would eliminate having to try to make the piston articulate in the opposite plane it needs to. Turn it sideways to the rest of the hammer, cut off everything not needed, and there you go.

Wow, is it really 3:00 in the morning? I hope that was a clear thought. :)
