Re: Knife Thread

Looks very nice and steady. The only problem would be if you have to move it :D . I envy you with my 30 sm piece of train rail. Can't wait to see some knives (or other stuff) forged on this thing.

Second, after the hammer strike, it will stay in the position that pushes open the gas valve causing the gase in the reservoir to empty, wasting most of the gas. this problem, however can be overcomed by using a spring that is slightly shorter than the length of the hammer housing, so the hammer st...
