Making a Slider

We wanted a slider for a shot in a car. The slider will enable us to have a moving pan whilst the characters are talking.
Originally we looked at the possibility of buying a slider, however these are expensive and in order to fit the car we needed ours to be 1.5m long, so that it can rest in the open windows.

For the slider we used:

*All measurements are in millimeters unless otherwise stated.

Two blocks of 120x50x30 scrap wood.

One block of 100x50x50 nylon.

Two 1.5m lengths of tubular steel, with a diameter of 22mm.

To start with, we cut the steel to the correct length and cleaned it with emery paper.

We then used a 22mm forstner drill bit to drill two holes in each of the wooden blocks, making sure that they were 60mm apart from each other so that the tubes stayed equal distance apart throughout. The holes went through about 2/3 of the block, so that the tubes would stay in place. 

Next, we measured and cut the nylon block, where the camera would sit.

We then drilled two 25mm holes through the nylon, allowing it to slide along the steel tubes. 

We then sprayed a silicone spray on the steel to make the nylon travel smoother, and fitted the end pieces of wood at each end of the tubes. 

Here is the finished result:
