HOW TO BUILD A LARGE CAMERA SLIDER DOLLY PLATFORM [DIY TUTORIAL]

Here's a short film on how to save money and build your own dolly. I don't have the exact measurements. It was so simple all I needed to do was:
1: Cut 2 wheel rails to the length of the board
2: Install the wheels onto rails (staggered)
3: Mount the rails parallel to each other

When installing wheels, insert the bolt in this order:
Bolt / Washer / Wheel / Washer / Nut / Rail / Nut

You can build it however size, however width, however length desired. You can drill more holes on the board so the wheel rails can be mounted wider or narrower. I believe this simple design is by far the most versatile. Materials cost me around $50.
Hope this helps! Please ask questions.
