[TheForge] Krause/Nazel type air hammer

Sun Dec 1 19:18:02 2002

Sounds like people want to keep it on list, which I also agree with.

Here are some questions:
What ram weight and stroke?
What are your cylinder sizes?
What stroke do you use on the drive cylinder?
What size ports do you have that they need enlarging?
How big is your motor?
Have you measured operating current on the motor? (i.e. how much HP does 
your machine consume)

I'm sure I have more...

Thanks very much,
Steve
