Hi all.
I was wondering if anyone though that a couple hundred pound concrete
"pillar" with an inch or two of steel on top (welded/bolted to the
internal rebar structure of the pillar) would provide reasonable
service for a treadle hammer? Or would we quickly be dealing with a
pile of gravel? I was thinking something like an 8"x8"x36".
Thanks,
don

Please log in for more thread options As described you will quickly fracture the concrete. You would need some
kind of shock absorber between the steel and concrete. I don't know if
this would work well as an anvil or not.
My friend was quite amazed at the damage his treadle hammer did to his
concrete driveway in a short time--no pad underneath.
Is concrete+labor that much cheaper than steel? Admitedly, steel has
gone up a fair bit.

Please log in for more thread options The question was partly practical, partly theoretical. I agree that in
the end steel is probably the way to go, but concrete is also a bit
more convenient to obtain and could offer some flexibility in design if
it would hold together. It's also easier to sneak past my wife.
Thanks,

Please log in for more thread options Just a thought, but lead might be cheaper, especailly if you can find a
pile of old tire weights.

You're gonna need a shock absorber or you'll have gravel right quick.
This might work..... take a couple of pipes and cast them into the
concrete vertically. These are the cylinder of your shocks. Thicken up
your top plate to at least three inches and weld two more pipes to the
bottom that will fit inside the pipes you cast into the concrete, so
there's a sliding fit. There should be at least a foot of 'overlap' in
the pipe joint for positional stability. Go to the truck stop and get a
couple of Rubber, not plastic, mudflaps and cut them up to fit flat
between the top of the concrete and the bottom of the top plate. Weld on
a sheetmetal skirt to the sides of the top plate to reach down over the
mudflap stack to shield it from splatter and radiant heat. Wait for
everything to set up, go to work. Consider the mudflap an expendable
component over time.
