I bought the pneumatic rock crusher and the mortar. The pneumatic rock crusher would not work with my smaller compressor. I don't have the best air hammer either. But I used the mortar anyway. I used a old sledge hammer head I bought in a yardsale, crushed the quart by hand. Between the head and a metal stake I got r done. I'll modify things a bit but the plexiglass cover I made for the pneumatic rock crusher doesn't work with my new set up.
