Mortar Boxes
What is a mortar box?
A mortar box is exactly what the name states. A box your going to fill with mortars. Each box, consists of two long sides
and two short sides, which form a frame with no top or bottom when assembled. These wooden frames are assembled using
metal rods, washers, and cotter pins, then filled with sand. These boxes are usually only used on the 4th when there are
simply not enough racks to go around. Sand boxes take much longer to fill than it takes to kleet an equivalent number of racks.
Mortar boxes are required if you are shooting out of steel tubes. By law, the steel tubes must be burried 2/3 of thier length in
the sand in case of a tube fragmentation.
How do you assemble a mortar box?
Very simply actually. Take the two small sides, or ends, and slide them in place between the two long sides. There are
six holes for the rods which hold the boxes together. Insert rod through both sides, put washers on both sides of the rod on
the outside of the box, and secure using the cotter pins.
