Camera Car Tricks
Three axle camera cars are smoother going over bumps because 5 wheels are always
on the ground when one tire goes over a bump. These cars are not as good on
rough ground because, on most, only one axle drives.
Video monitors of the video assist helps the driver. Well shaded 4" to 6 " are
fine. They can usually be run off the car's battery.
Triangulation
Camera car hardware relies mostly on parallel bars with very tight fittings
on 2" OD (outside diameter) tube. (See tube and pipe). Not many camera cars
use triangular bracing. I have made some adapters that make 2" (2-3/8" OD) Speed
Rail fittings useful with 2" IPS aluminum pipe. These are 2" diameter scaffold
fittings welded to 6" stubs of 2" IPS pipe. I use 1-1/4 pipe and scaffold crossed
for triangular bracing. The new Doughty fittings will adjust from 1-1/4 IPS
pipe to 2" OD tube. Industrial Metals has the Doughty line which Hollander Mfg.
has taken over. In Europe the stuff may be a little more reasonable.
