Benchwork 4

Benchwork continues in Zone 2 and 4. The upper and lower front L-girders are assembled and installed.

The first step is temporarily clamping a vertical 1"x3" to the valence.

  

With a length of 29-feet, i used three 10-foot 1"x4"s for the top L-girders.The first L-girder is clamped to the end L-girder. The other end of the L-girder is clamped at the vertical with a second clamp.  Each L-girder is leveled horizontally with a 4-foot level and cross leveled with a 2-foot level. Once correctly leveled the L-girder is attached at the end with a rafter angle plate and temporarily screwed at the other end to the vertical 1"x3".

At the other end of the wall a second L-girder is attached and installed in the same manner.

The third (center) L-girder is aligned with the two end L-girder and cut to fit. A rafter splice plate is then screwed at each connection point.

When all L-girders are leveled I then install two wires attached between the valence and the upper L-girder and legs between the lower L-girder and the floor.
