Subject: Concrete Block framework for horizontal sensor.


I wonder if anyone has had any experience using standard concrete blocks to
form the "L" framework for a horizontal sensor.
 
For the pivots I would be using crossed rods top and bottom.  I would cement
in place the mounts for these and make the top adjustable for leveling.
 
This amounts to taking my horizontal sensor which constructed on a AL
channel frame, and moving it over to the concrete frame.  I have the space
to do this.
The aluminum frame is currently apart and was being readied for welding.
 
Any comments or suggestions.?
 
I have been running my vertical for about a year now and want to get the
horizontal going again in a permanent manner.
