The California Modified Automatic Soil Compactor is supplied with 2in (51mm) round 10lb hammer only. Required piston and rod are included as parts of the machine.
The California Modified Automatic Soil Compactor can be used with the 4in (102mm) ID molds, 5.5lb (2.5kg) weight with 12in (305mm) drop. The standard 2in (51mm) hammer can be replaced by one of the same 3.14in2 area, but with pie-shaped face to cover entire sample surface with 6in molds. The hammer lift compensates hammer drop for soil thickness in the mold during compaction. The free-fall hammer has weight concentrated at the foot and adjusts easily from 5.5-10lb by addition of a surcharge weight.
