[Towertalk] Tower Base

Bruce et al

There is always a limit to the depth of a hole with respect to the width.
Unless you plan on drilling a cylinder, or using a large machine with a tall
reach and small bucket, you can expect similar results. Just because they
specify those numbers, doesn't mean they're realistically achieved.
