The base of Dolly is 4 x 2 ft 4 ply with a centre (hinged)
for storage and space).


The plumbers plastic tube is approx 40 mm diameter and is
joined together with small inserts.

The roller skate wheels are bolted to a frame beneath 4 ply
boards and the handles are from lawn mowers adapted to
base.

The 3 armchair cups are fixed to base to allow tripod to be
secured and kept in place with rubber hooks.

The completed system allows long tracking shots without any
jolts or unwanted movement and cost approx £30
for materials.
It is a very cheap tracking
device which can be pulled along forward or backwards with adjustable handles
and is strong enough to stand on if required.

The whole unit folds up for easy storage and transporting to and from venues.

The most important aspect is that no matter how many bumps
on grass or road surface, it runs very smoothly.
