Build Instructions

The build instructions below are divided into two parts, namely pre-assembly and final assembly. In the pre-assembly some of the sub-assmeblies or parts are either prepared or assembled together to ease the final assembly. The number in the (#) paranthesis denotes the quantity of the part required.
