[TheForge] My Powerhammer is done!

Wed Mar 19 00:40:01 2003

Hey Shannell,
          The wheel idea isn't mine.  I got it from www.anvilfire.com (NC-JYH) 
I had the same problem with the shock stealing power so I lengthened the shock 
so that it is hitting when the connection to the wheel is just below 
horizontal.  That means that the hammer is hitting when it's almost at it's 
fastest.  It compresses into the strike.  It lessened the distance between the 
hammer and the anvil but it increased the power of the strike.  It also means 
that shock is in compression about 45% of the time....a bit more bending 
pressure on the rod coming out of the flywheel...may need a bigger diameter 
rod.....haven't given it the full test yet....later this weekend maybe...I'll 
post MP3 of it running

Later

Dan
