Acting like hitting a rock with another rock is rocket science is absurd. Acting like lifting bosses are anything but lifting bosses is absurd. Talking to a professional craftsman about lifting bosses being more than lifting bosses, and telling them they have no idea what they are talking about is absurd. That is the end of the discussion. Oh, and people still build shit like this, all the time. Acting like they don’t is absurd. Laymen build these things in thier backyards ffs.
