Scott had always wanted to make some sort of ball bearing rollercoaster and we thought we'd post up the results of his first testing and building sessions.
The idea was to make track for ball bearings (or similar) out of something that was fairly quick and easy to work.
Scott found that mains cable copper wire was perfect for this, go to the next step to see a list of ingredients for this project and get cracking.
It is assumed that you have access to a workbench / desk and that you can use tools like soldering iron, wire cutters and so on.
Step 1: Ingredients
- Ball bearings (we used 5mm)
- Battery drill/screwdriver (ours is the cannibalised motor from an old one)
- Small drill bits (that match the diameter of the wire you will be using)
- Mains wire (we ended up getting a big roll but you can use the grey sort, often easy to get from skips or lying around. You'll want the stuff that is quite stiff, we found 2.5mm squared core to be best)
- Pliers / wire cutters
- Soldering iron + solder (we ended up modifying our soldering iron tip for best soldering)
- Small motor (ours is from and old zoom lens, you could maybe take apart an old CD drive to get the tray motor or similar - post up what you use)
- Spirit level/s
- Chipboard / ply board (for jig and for mounting the rollercoaster)
- Matches (for jig)
- Glue (we used hot melt glue gun and some wood glue)
- Sharp knife (Stanley or similar)
Once you have this lot, you can get making!
