From what I can find on this forum (and elsewhere), few blacksmiths have anvils in the (roughly) 70-90 lb range... or at least they don't talk about them much.
I'm getting into the craft as a hobby. I'm not planning on forging anything huge in the near future -- I want to work on smaller projects (hooks and brackets, handles, small sculpture, etc.). I'm also attracted to the idea of a workable-but-still-portable anvil (that almost sounds like an oxymoron -- something like the NC Tool Short Sugar.
So, what are the LIMITS of a 70 lb. anvil? At what point does it become unreasonably light?
Finally, as far as the physics are concerned, is it correct to say that the decreased mass of small anvils results in a less elastic collision, meaning more effort on the part of the blacksmith (since the anvil doesn't "hit back" as hard) and more shock being transferred to the anvil stand?
Thanks!
