[TowerTalk] rotary or demo hammer for ground rods

[Jim Hoge <knowkode@verizon.net>]

Hi gang,

I am in the market for a rotary or demo hammer for remodeling work. I am 
looking at tools that deliver 7-10# percussive force (10-14 joules).What is the 
size recommendation for a rotary or demo hammer for driving ground rods? I'm 
sure that soil conditions play a large part but what is the minimum that will 
drive a ground rod in a timely manner? It would be nice to have a use for the 
tool once the work is done.

Tnx es 73,
Jim W5QM
