highground I just ran into a guy who uses liquid nails with 10" lag screws. I guess he drills a pilot hole first, or maybe he runs the lag in then takes it out to pump in the Liquid nails, forgot to ask.

Well, welcome to Continental European wiring!
The only difference being, most of our buildings (except for some rural farm houses) are rock solid brick instead of adobe, including all interior walls.
You either need a slot cutter (basically an angle grinder with two parallel blades and dust collector) and chip out what's left between the two cuts (very common in Germany) or a rotary hammer drill with a flat chisel bit (most common in Austria, less dusty and less likely to hit live old wiring). In the old days they did everything with a cold chisel and sledge hammer (usually 4lbs.), for smaller jobs that's still used.
On my summer job we channeled rock solid brick walls for 2 1/2" conduit with hand tools. Go figure...

Well the long lag bolts worked like a champ, in fact the 10 inch ones got so hard to turn the last 3 - 4 inches I thought they would break. I went and got some 8 inch ones, they hold unbelievably well. Larry, my plan for thru bolting fizzled when I discovered a tiled tub surround right where the panel had to go.
Thanks highground for the idea. I couldn't get ¼ inch lags longer than 4 inches so I used 3/8.

Arizona, where you can hardly get a panel to stick to the wall then you spend 3 hours with a 60 lb demolition hammer to drive the ground rods.
