Re: [ATM] Astig. due to gravity

You forgot those of us that don't have basements!
You need to use the chainsaw to dig out the concrete and dig a
hole in the ground for the necessary distance plus stairs to get
down there.  You also need to watch out for high groundwater
(mine is three feet down!)and rocks which can make the digging
more difficult.  Use of explosives is not recommended even though
you can get the formulas for many of them off of the web as the
whole house may not enjoy the results with the commimentment
frying pan upside the head from the wife.
