As I have discussed in the last couple of posts my intent is to use magnets and dowels to pin the terrain to the modules of my micro RC race track. The initial inspiration for this system came from user ‘Healzonu’ on the Ultimate RC Forums and I have developed the concept further for use on my track. For those playing along at home, this is how you make the hole array for the first time in four easy steps.
Tools And Equipment
To do this you will need:
- Two B1 sized plots/prints of the hole pattern template (see the printables page). You can do this with only one print if you want as the B1 layout only covers half of a module. You will have to flip it around to do the second half if you only use one print.
- A drill.
- A drill bit corresponding the the size dowels/magnets you are intending to use. I actually used a 1/4″ bit for 6mm magnets to make the hole just slightly oversized.
- Tape. Masking tape is best but almost any will do.

Now I have the idea for a magnetic dowel system to position the terrain the base modules need to have holes drilled in them. This array of holes is used to pin the terrain into the plywood with the dowels.
I intend on using 6mm diameter magnets and wood dowels for the job as a starting point. It is prudent to start with small holes and make them bigger if stronger magnets are required. I am also starting with a 50mm array of holes and the module will fit a 23 rows and 11 columns with this array size making a total of 253 holes.
Rather than mark out the array on the module using a pencil and a straight edge I have decided a little more accuracy is required, so back into the CAD system and a quick layout was generated for half the hole array that can be printed to a B1 sized layout. If you want to follow along at home a PDF of the hole pattern layout will be available on the printables page. You can get this printed anywhere that does roll size plan plots. I had mine done at Officeworks here in Australia but there are many place around the world that do it such as ‘Fed-Ex Office ‘ (Kinkos).
In my next post I will take you through the simple steps to using the hole pattern template.
