Step 1: Tools and Materials
Rotary tool with stainless steel wire brush wheel
1/8 inch diameter stainless steel rod
3/16 inch diameter stainless steel rod
Not all of the tools in this list are required, but will make the construction much easier. Your build may need more or less than what I show. This may also vary based on the material that you construct your marble track and cabinet with.
NOTE: If you plan on using any tool for a project please make sure you are familiar with the tool and all of the dangers associated with it. If you are not familiar with a tool then you should ask someone who is to show you the proper way to use it. A lot of communities have classes at local colleges on the proper use of tools and machinery. There are also local woodworking clubs that offer classes at very reasonable rates for beginners. I highly recommend using these resources for your safety and for the most efficient use of the tool.
Always wear eye and hearing protection.
Always work safe with the proper safety equipment and guards on your tools.
