Then wath type of anvil are you making?

Are you planning to make an european anvil by casting or fabricataion?

I could be wrong, but it looks like your universal holder has already been invented, refined, and mass produced, i.e. a plate with holes in it to universally hold differently sized stakes and tooling: PEXTO STAKE PLATE http://cgi.ebay.com/981-PEXTO-STAKE-PLATE-Blacksmith-Anvil-NO-RES_W0QQitemZ120523668022QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item1c0fc53a36 I have also seen a smaller modern-made stake plate holder for less than $80 on EBay many times. You can't get much simpler or less expensive than a small steel or cast plate with square holes in it.
