[TheForge] Weightless Hammer

Tue Nov 12 10:04:01 2002

Bruce,

I took a look after you posted on the keenjunk site. Very nice drawings and directions. I'm wondering if you have built one using the plans and how it works "in the flesh"?

Looks like you spent a lot of time on it. Thanks.

>lightweight jib crane. A specially designed bale allows the hammer to strike in virtually any direction except straight up. Being weightless, the hammer can be lifted
>repeatedly with little effort for multiple blows. The user must accelerate the hammer for the blow, but this requires no unusual strength. If constructed with a

>This machine is designed to be easily constructed at moderate cost from commonly available hardware using a minimum of hand power tools. The machine is not
>free-standing, but is designed to pivot on the floor and at a rafter or joist. The machine is transportable, weighing only 60 lbs, including the 16-lb sledge, and may be
>easily carried on a car roof rack.
