Big Anvil

[Whiskeysup]

Was at the Lanesville Indiana Heritage festival yesterday(crazy about old tractors,machinery etc.) when I saw a couple of blacksmiths giving demonstrations. He said he made the pattern out of styrofoam and had it cast. Beautiful and impresive.

WOW!  862 lbs.  That's a monster.  You don't move that puppy around with a two-wheeled hand dolly (more like a fork lift)!!  Do you know if that's a forge welded face?  Looks like a seam of some sort.

Arkie, I noticed that too.

I am guessing that is a milling machine mark from when it was cleaned up after casting. No need to put a face on a cast steel anvil.

I agree no need for an attached face on cast steel, just curious. Don't think it's a milling machine mark...that would be a perfectly straight line. Maybe some residual something in the casting mold.

Arkie it would only be a straight line if the surface was straight.

If you place the anvil, which *should* have a *flat* base prior to milling (if it's done right), on a flat surface (milling machine) and run the milling cutters across the top, then it would be a flat surface; i.e. straight line on the side.

[BIGGUNDOCTOR]

If the anvil is standing up on the mill, and  you run an end mill along the side, and the side as undulations of even just a few thousands you will get a wavy edge. Being a casting I would not expect the sides to be perfectly flat or smooth.

[arkie]

I think we're talking about two different things...no need to pursue it any further.

Any idea on alloy and heat treat?

1030 low carbon surface treated on flat face not horn.

How do you know this? If it is your anvil please tell us more.
