I don't believe there's anything unique about this design - there's probably others on this website, but I wanted to make an Instructable and since I made and used this contraption I thought it was a good place to start.
The video link is the shot I used this getup to get. Full video at the end of the instructable.
Step 1: Parts You'll Need
- 4x wheels. I used an goofy-boot and stole it's wheels. (I could return them to the skate but I prefer the one legged workout)
- 5x PVC pipe end-caps.
- 5 times nuts and bolts with washers. (more on those in a sec.)
- 3x PVC T joint
- 2x PVC elbows
- 1x PVC pipe of some length. That's up to you. I bought a fresh one from Rona and have plenty left over.
As for trhe size of the pipe – It's some standard size.
So between the last photo and this you've got enough info to build this. Here are the details…
Step 2: Spinning Bits
I drilled a hole in each of the caps and bolted the wheel with the hex on the outside and the locking nuts next to the plastic of the PVC pipe so that it's tight but the wheel spins freely - obviously that's important.
Step 3: Camera Mount
I used the extra nut/bolt combo to attach it to the extra end cap, like the wheels.
Step 4: Body Parts
So 7 x 4inch PVC pipes in total.
Step 5: Assemble
No glue needed.
This setup allows you to twist the pipes to set the angle of the wheels. As well, the neck and be adjested up and down, sort of, by rotating it along the axis of the body.
This set-up is good for light duty dollying on a flat surface with a smaller camera. A full sized SLR would work for a while but you'd want to glue some bits together for added stability.
Anyway, This design got me out of a jam, maybe you will find it useful.
