Flywheel added to the Red Caboose GP9 September 27, 2015 13:54
A little extra space was need between the drive shafts to add a flywheel. Instead of hunting down shorter shafts it is easy enough to remove the spacer between the drive shaft halves. The half's are then reconnected with a 1/8" x .3" section of steel shaft. Enough space was gained to fit in a 1.2" x .75" flywheel made from mild steel.
