Finally it is finished. After a broken arm, a severed thumb, and a lot designing and troubleshooting the Marble Race Masterpiece is finally finished. At first this did not seem all that complicated to build. We came up with the types of tracks we wanted and simply started making them separately. Once we had two or three of the levels finished that was when things started to get complicated. We had to figure out a way to stack them all together. We picked an order, then had to change it around. We also continued to add to new tracks to the Marble Race until we had seven total levels.
At first we wanted to see if we could avoid gluing each level in place, you know, to make it easy to disassemble and ship if necessary. Sadly this brilliant plan was not meant to be. The four posts for the tower began to twist and warp because the tension was so high. In turn, this caused some of the tracks to slip out of alignment and marbles would fall off and fall out in all the wrong places. So, in the end, we bit the bullet and glued it all together. We coated it with a polyurethane protector. We even added a base (not pictured) to catch all the marbles when the race was over. It is stunning, and really really fun.
Our little boy loves to run marbles on this track. He has to stand on his tip-toes to even reach the start switch, and he cant see the first two levels just yet, because he is such a shorty, but once it hits eye level he smiles and follows the marbles running down, down, down. He always tries to catch the marbles in the plinko section before they drop down to the next level. It is pretty fun to watch him get so animated and excited with his fists full of colored marbles.
Here are the tracks in order:
1. start switch and two straight tracks
2. zig zag
4. two straight tracks into bowl funnels
6. switch plate
7. half pipe
