Splitting igneous Basalt using wedges and shims.

["Sam" <leijen@zzzzzzzzzz>]

Thanks Bill for the speedy reply.

The rock is about 800 mm through and 1 metre high.
It is an oval shape actually.

I drilled into the rock 120 mm which was enough to place the shims fully in.

I hear what you are saying about "not enough wedges"
I'll get some more and try again.

Are the spacings correct?

Thanks
