Basic hammer plans

Anyone built this hammer?

this fellow came up with those plans:

Yes. Finished my in December. Works great.

I read that the author was nearly killed by this machine and that's why the plans got pulled but one could die in a car on the side walk plane so I wonder was it the fault of the machine? and dose the ol adage apply never blame the tools.

There is a noteworthy lack of guards on the machine in the video and in the plans.

I totally agree it should have (more)some guards unfortunately there isn't any info on what happened the nearest thing would be the hammer end spring broke either flicking out and over the top or coming straight through with the downward force of the hammer I would suggest a guard around the top motor and lifting rod some photos I've seen do show home made guards covering most of these areas
