Careful son, there's scary stuff in there!

This is odd. The wire that leads from the switch to the motor is a lighter gauge than the wire in the cord. That can probably be improved. I also don't like the way the cord is above the handle so perhaps I'll relocate it below the switch.
As I review the videos on Youtube I noticed several sanders pop a bit of a wheelie at the start of the race, and having the cord lower may lower the center of gravity a tad. Additionally if the cord hits a snag during the race having it lower might keep it from tipping up. Can't hurt. (I think)
