[TheForge] In- line hammer

[Lynn and Susan Lang]

Hello

Am looking into building an inline hammer and at first look these
questions come to mind....

What is the usual poundage of the head?

What would be the typical force required by the operator to operate the
hammer?

If the head is round, what is used to restrict rotation of the head?


If you were to build one, what features would you build in?

Thank you
