User Comments:
• This is the very top of the steam stamp. The upright shaft near the bottom of the machine is the actual rod that would reciprocate up and down. Below this floor would be the business end" of the stamp, i.e., at the bottom of that rod or shaft would be a large and heavy "stamp shoe" which would set in an angled "mortar box." The up and down motion of the stamp on broken rock in the mortar box would cause it to be crushed to a smaller size."
