How to erect: 
1.  All wood is 4" by 4" pressure treated. 
2.  The cross of Jesus is 16' in vertical height (13' above ground level) by 8' in horizontal length.  The 8' horizontal piece is 3' below the top of the vertical piece.  The crosses of the two robbers are 12' in vertical height (10' above ground level) by 6' in horizontal length.  The two 6' horizontal pieces are 2' below the top of the vertical pieces.  Each piece is notched out, then glued and nailed together. 
     Jesus' cross is painted white on each face and on all sides, while the robbers' crosses are painted only on each face so that when viewing them from either direction the white will always be on the right of Jesus and the black will always be on the left of Jesus. 
     All 3 crosses are set in concrete. 
3.  If possible the 3 crosses should face east and west to try and prevent turning of the wood by the sun.
