[TheForge] Home built power hammer question

[Andrew Vida]

1 Rev per second is not very fast, so unless you have a lot of push 
behind it, you are not going to get a lot done.  Speed it up, but do it 
incrementally so you don't have the hammer come flying apart in the 
event you didn't engineer something quite sufficiently.
