This was our main project today. We have entered a fun part that involves actually running this thing on the track to see if all of our hard work will pay off! We knew from our previous experiments that we were going to have to weight the trucks, so I grabbed a pair of 2# dive weights as Kid-zilla prepped Mack for duty.
Initial runs showed that we had overtightened the arms…
…and that we needed to fix the trucks to their platforms. This required some disassembly…
…followed by CA glue and reassembly. When that was all down, Kid-zilla took a moment to see just how big his creation is!
After derailments, we placed a short flat car between Mack and the rig to see if that would help.
Maybe, but Mack was spinning, so we brought out a helper, Kolea, which Kid-zilla informed me is Mack’s girlfriend (I keep a few cars between them at night, as they are not married! The Triple O is a PG affair!).
Alas! Poor Mack is wired opposite to Kolea, so we had to bring out Mike Bananapeal for the remainder of the trials.

There were a few pinch points, and more revealed themselves when we placed his submarine on the cradle and took it slowly around the tracks.
Frankly, I am surprised it worked that well! Part of the issue is the lack of straightaway to allow the cradle to line with track before it hits the next curve. We can route this rig around that building, luckily, and we can always trim / tie the plants.
So where does that leave us besides arboring? First, as I still need my dive weights, we have to find up to 4# of weight to balance everything. Kid-zilla suggested some sort of box. I am not sure what we would put in that box! Second, we need to add some steps, tie downs, lettering, etc. to bring this to life. Finally, I need to figure out how to open Mack so I can reverse the wires on his motor and let him pull this rig with his girlfriend!
Even if the final project is a “set out” piece, knowing it COULD work will make bringing this over the line worth our time.
