Thanks for the tip on the Multi-router. I’m not sure how it works so I ordered a video on it. It looks very interesting.
Mcnotashark:
We currently do use jigs in our production. We keep things pretty close to tolerances but not close enough. The reason why accuracy is so important is because if you have cubes that are off, by the time you stack 6 of them high you create a lip. When the marble hits this lip it slows or even stops it completely. The tighter the tolerances, the smoother and faster the marble rolls. Woodworking equipment is just not made for that precision. True, the wood itself is a variable that does not lend well to accuracy either BUT.. With choosing very dense hardwood, controlling moisture content in the environment and lastly, “impregnating” the cube with a sealant has worked well to combat variances.
I would love to get a CNC router, but I can’t find one under 3k that would work.
One last question and I won’t bug you guys again
I want to find out if the Multi-router will work first, but I’m leaning towards getting the grizzly G1007

It has a power feed so I can do what mcnotashark suggested by just lining up the cubes. Here is my question. If I make a custom pulley for this machine to gets speeds of around 10,000 RPM, would the bearings be able to take it? It’s a 2HP motor so it should have the torque.
Thanks again to all of the feedback I got.
