[RE-wrenches] Mounting on rock

[Mac Lewis]

Hi Aaron,

Granite is a great substrate to mount to (once it's done). You could weld a
large flange plate onto the bottom of your pole, and bolt it to the granite
using anchor bolts. Rock climbers (including myself) drill into granite all
of the time.  Bosch, among others, has a great drill and bit setup that
works well. Glue in epoxies are a great way to keep moisture out of the
hole for many years.

Ballast racks are available too but it seems like a shame not to attach to
the granite in some way.

Good luck
