[TheForge] treadle hammer anvils

Bob,
Maybe you could be clever and design a built-up anvil that BOLTS together =
with a minimum of bolts.  I'm thinking of something like an I-beam, stood =
on end, with a face plate (maybe 6" sqaure of 1" steel), as the "skeleton" =
of the anvil,with pieces that bolt to either side the web, between the =
flanges, to add mass.  The hard part would be to ensure that these pieces =
make sufficiently firm contact with the face plate that their mass makes a =
difference in the behavior of the anvil.  You'd want is such that =
tightening the bolts would tend to press the ends of these pieces firmly =
against the bottom of the face plate.  Angled studs might do this, or =
perhaps some affair involving wedges.

Bob,

The treadle hammer (finished and kits) that Centaur sells are from=20
Kirkpatric, I don't know about the one advertised in the hammers blow.  =
But=20
the Centaur/Kirkpatric ones do not have the adjustable head height.

Personally I'm a proponent of the solid or built up (i.e 4 2"x3" steel=20
bars).  Just like a regular anvil, the solid body provides more =
"rebound"=20
effect than do the tubular anvil bases.   I'll admit that the solid body =
is=20
heavier than an empty tube and may make it more easily moved.  But if =
the=20
tube is filled with concrete and scrap steel then there might not be so=20
much difference.

I guess in the end you get what you want.  The empty tube base will =
work,=20
but may not be as good as a solid base.  But if it does what you want =
it=20
to, then I suppose it's just fine.

Then again, I'm not an expert in these things, just opinionated.
