Edmund Scientific stuff to build your own dolly track,,...

Some cool stuff from Edmund Scientific. You could combine elements
together to make a precision dolly/truck/lift track.


These are lab-jacks. They will give precise vertical camera movement by a
simple turn of the knob:

This is a rack and pinion track:

The rack and pinion track was popular back in the 70's. it was advertised
extensively in "Super-8 Filmaker" and "Cinemagic".

My solution was to get a $20 RV levelling jack, used to jack up the
corners of mobile homes. It's just like a scissors jack for a car, but
twice as big (or bigger), and rather than having a funky hook at the top
that's made to fit into a slot in the frame of the car, it's got a flat
plate with some mounting holes... perfect for attaching a camera. The base
also has mounting holes, which were a perfect fit for the T-slot bolts on
my machinist's table for side-to-side and forward/backward motion. The
movement is a lot smoother than the lab jack I bought. For anyone who
hasn't seen this already, I have my camera-jack system documented on my
website: www.darkstrider.net/Camsyst.html

My setup is limited to only 11" travel along one axis, and I think 7" the
other way, but has an incredible 20" of lift. I'd like to step up to a
better slide one day, and was thinkjing about a couple of drawer slides,
but that slide you linked to might be better (Haven't really checked out
the specs yet).

I know this subject has been covered to death but I would like to add
another solution. I just picked up a Bolex Super Titling Bench from Ebay
with the thought of doing titles the old fasioned way and it occured to me
it could be used for dolley shots. One of its features is to do a moving
camera shot. This is acheived by moving the carriage on the slider posts.
It even has a ruler built in for measurement. Total travel is about 27.5".
The bench can be positioned horizontal or vertical. You would need some
kind of adapter if you want to do vertical moves to keep the camera
horizontal or if that's the camera angle you want, then you're fine. You
would also have to secure it somehow so it doesn't move around when you
are moving the carriage. You could also use the bench to do traditional
cell animation in the vertical position. The bench is really well built.
This system is not as sophisticated like some other home built solutions
presented here but it may provide a cheaper way to do dolley shots. Here
is a good description of it here and it can also be found in the "Bolex
Bible" book:

There's a bench on Ebay right now that shows a clear picture of the
platform with the ruler attached. Item number: 3849533801. It is only the
bench and not all the accessories found in the super titler kit.

It's probably not the most user friendly description of what I did, but
hopefully it will work.
