I added several new features this week. More ramps, turns and modifications. The marbles are rolling nicely. I covered the motor with an old leather apron to protect it from the welding sparks.
I used a old wok, which we found at a thrift store, to add a cool bowl effect at the end of the marble run. A little bit of grinding and the bowl is looking good!
Some of the final pieces and track are in place. We are getting close.
