The ad says it has a "crack" - that's not a "crack" its a complete fracture making the broken horn even more useless as a working anvil. Maybe a curio in a garden is all its good for.

For those that are unaware the going price for anvils in the US ar between US$3 and $6 a lb so a 100 lb anvil in V good condition might be US$500.
Prices (AUS$4.50 and $9 per /lb) are similar here in Oz.

I managed to pick up a 70 year old 112 lb anvil in ordinary to fair condition some 8 years ago for $2.70/lb and I consider that a bargain.

You Guys wouldn't want to start collecting saw doctors anvils then, they cost twice as much as blacksmiths anvils.

One of these would do me.

German Refflinghaus style: 90% rebound, weighs in at 210kg, and priced at $6K.

There are more expensive ones around but I did not want to be too greedy!

Should polish up very nicely, BobL, But then what would you do with it? You wouldn't want to belt it with a hammer and undo all that polishing.

Apparently if you belt this one with a hammer >90% of the energy comes right back at you or into the hammer!

Cheers Matt.

One way is to drop steel balls onto the anvil with a ruler held vertical near the drop point and record the rebound process with a slow mo video camera. Freeze frame the max height of ball rebound and read the height using the ruler. Simple when you think about it

Another way is to drop a ball bearing inside a clear PVC or PC tube onto the anvil
Then quickly mark with a felt tipped marker where the bottom of the ball reaches it's max height on rebound on the side of tube

Another way it to mark the half height on the side of the tube and count the number of bounces it takes for the bottom of the ball to reach just above that height.
A 90% return will have 5 bounces.
10 bounces should reach 30% of original height.
It works best with a heavy ball as the relative frictional losses against the side of the tube are then minimised.

It reminds me of the "legend" of the blokes who were asked how they would measure the height of a tall build with a barometer.
The first guy said, measure air pressure at ground floor and again at the top floor and do some calculations.
Next bloke said, climb to top floor and throw barometer off building and time how long it takes to reach the ground
Third bloke said, don't bother climbing the bloody building, offer the barometer as a bribe to the building manager to tell you the height of the building.

Thanks Bob,
Shortly after asking the question, the light bulb flicker ever so slightly.
An I thought yes just measured a steel ball rebounding.
