[Fot] SLOT CAR RACING SYSTEM

[Kas Kastner]

Now you have a racer that handles just about the same. Whoopee !!!

Are you okay from the weather problems? The trees would need to go three
floors to get the important stuff. :-)

  Used to be that all the good controllers had brakes--at the very
  least a "dynamic" braking system that shorted the motor for braking,
  at the best, a reverse voltage to give serious braking. I was really
  into slot cars in the early 60's, to the degree that I worked for
  "Frank Malzone's Pit Stop" a short-lived commercial track in Boston.
  I built my own stuff, including a two-speed axle that used a motor
  reverser to shift. No brakes if you were in the low gear when you let
  off, but if you were in high then you got an automatic downshift and
  "engine" braking. The axle used two bevel crown wheels facing each
  other on both sides of the pinion attached to the axle with ball
  bearing sprag clutchs, and two pinion gears on the motor shaft. I
  also built an automatic transmission that used a rubber wheel drive
  on a steel disk that was pulled towards the inside of the disk (high
  gear) by a light spring. The shifting adjustment was the angle of the
  motor in respect to the disk. Under load the motor woud pivot so the
  drive wheel slid to the outside edge and give lots of torque, then as
  the wheel RPMs built it would work inward for higher gears--like a
  snowmobile trans.

  Of course none of this stuff delivered any advantage, the best setup
  was a well-suspended light car with a hot motor.  So I started
  building motors. My meanest was a few turns of silver wire per pole
  on an epoxied mabuchi armature carefully balanced on a razor blade
  balancing fixture. It drew so much current that the pickups smoked.
  It would toast a controller in about ten minutes of use.

  Fun stuff. My favorite car was a BRM that I worked over for months
  until the suspension functioned so well it could take serious turns
  at nearly full speed. The big breakthrough was Z-type anti-sway bars
  that transferred lots of force to the outside wheels, keeping the car
  flat and the pickups on the conductors. The magnet trick wouldn't
  work on those tracks, we used copper braid for the conductors.

  I think I was about 14--I know I didn't have a driver's license. I
  burnt out on the hobby and started building motorcycles, haven't
  touched one since then, though someone gave me a Williams F1
  Scalectric set a few years ago.
