[TowerTalk] Ground System: Equipment Ground

[Jerry]

I've been "redoing" my grounding system with arrestors, new control 
boxes, new underground cable runs, etc. and now am faced with adding my 
equipment ground to the SPG at the entrance of my shack.  My first 
thought was to purchase a 6-8 ft copper ground  bar to attached each 
piece of equipment....and then a length of #2 to the SPG.  That is, 
until I found out the cost of copper bars these days.  Any suggestions 
for a substitute?  Would a length of 1/2 or 3/4 inch copper pipe work 
okay?  What would be the best way to connect the equipments' grounding 
straps to this pipe?  Your ideas would be appreciated.
I hope this is an allowed question for this mail group.  If not, please 
excuse the bandwidth.
Tnx & 73
