There are many styles of scaffolding. The most rigid are made by Up Right for
temporary antenna towers, but the top is small, 4' by 6'. They are unfortunately
all one folding section and difficult to erect on top of each other without
the correct devices. Two sections of these can be connected together and tilted
up together for a very stable 12' high shooting platform. DO ERECT A SAFETY
With all types of scaffolding, starting level is important. Putting 1 foot by
1 foot pads on sand or soft ground is better than on a large piece of plywood
that will rock if the ground is not perfectly level. Screw leveling pads help.
Casters should be used only on hard surfaces.
Regular scaffolding can be made more rigid by adding extra diagonal bracing
that pulls one section tighter against the existing bracing. Tensioned rope
or pipe will do.
The standard top safety rails are only for safety and are not rigid enough for
rigging. You can add to an existing railing or build your own. Splicing pipe
onto the risers will be very strong if the right type of connectors are used.
Chain pliers, hose clamps, Kant Twist clamps and ladder chain with bolts will
work. Three way crosses will work for railing corners, but are hard to align
pipe into. Individual crosses are easier to use. The Kee Klamp #45 cross is
easier to align than the longer Speed Rail #10 or #30A crosses.
DO NOT BUILD SCAFFOLD TYPE STRUCTURES FROM SPEED RAIL AND KEE KLAMP FITTINGS,
THEY ARE NOT DESIGNED FOR THIS AND WILL FAIL IF STRESSED BEYOND THEIR LIMIT.
Top railings can be made with Speed Rail and Kee Klamps if care is used.
When building a deck, two thicknesses of 3/4 or one piece of 1" plywood is stronger.
Planks flat or 2" x 4" on edge can help support the tripod legs. USE CARE WITH
HEAVY MATERIALS UP HIGH. A single sheet of 3/4 ply will bend under the weight
of the camera crew and move the tripod legs.
