Designing a marble track from scratch

marble

 

Woodworker extraordinaire [Matthais] was approached by a toy company to create a ‘marble run’ toy. [Matthais]‘ jig-building skills are beyond reproach, so whipping up a prototype for this toy was pretty easy for him.

The basic unit of construction for this marble run is a simple ramp block with inputs and outputs at either end. These were crafted from blocks of wood, with the ramp carved out with a slot mortising machine. To make the side cuts on each block, [Matthais] used his pantograph router and a jig that cuts the wood for marble inputs on either side.

After taking his creation to a hackerspace for some very large kids to play with, [Matthais] found a few problems with his initial design. The blocks didn’t want to stay aligned when marbles were moving down the ramps, so a small mortise and tenon – looking very much like a piece of Lego – were added in several locations on the underside of each block.

Making one of something is relatively easy, but [Matthais] is making hundreds of pieces for his marble run prototype, each interchangeable with another. That’s impressive for something crafted by hand, but when you’re a master at making jigs like [Matthais], everything goes by pretty easily.

    That’s the woodgears.ca guy. His name is actually ‘Matthias’. He does great things with wood.
