Rock splitting
Using a motorized drill/breaker, you can split large rocks
safely and accurately.
Start by drilling holes in a straight line across the rock
you want to split. The holes should be about 30-40 cm
(12”-16”) apart and at least 40 cm (16”) deep.
Insert feathers and wedges along the line. Drive in each
wedge a little at a time until the rock splits. Some grease
applied to the wedges makes the job easier.
