The GRW is a full
motion mechanism specifically designed for plywood and other flat-bottomed
Pinewood Derby tracks. It operates by remote control to start your race
with nobody near the track. The GRW mounts to the bottom of your track
with four self tapping screws included. The electronics portion of the
unit is integrated with the actuating mechanism.
The actuating component
is a powerful rotary solenoid which rotates your existing peg bar by
a brass pull rod. There is wide variety in homemade wood tracks, so
we will need to discuss your situation as to the mounting details. Photos
of your track are very helpful.

The GRW is designed to work
best with light weight peg bars. Some peg bars are not suitable. For
example, the Classic Piantedosi wood track has a peg bar made from a
5/4 x 3 board, extended 6 inches on either side of the track. Its large
rotational inertia is beyond the capabilities of the GRW.
We offer quality light weight
gates consisting of a hinged aluminum angle with vinyl-covered stainless
steel pegs to fit any track.
Additionally we can integrate
the entire system on to a 1/2" substrate of MDF, to save you the
assembly time, optimize performance, and make the system easily removable
for storage. Contact us for pricing.

New!
The GRW now has
a big brother!
Weighing in at
2 pounds, 10 oz, and generating three times the torque, the GRWB is
not needed for 6 lane tracks, but could be considered for 8 lane tracks
and above. Or for unlimited class races where heavy cars are allowed
and empty lanes are common. The high torque eliminates the need to adjust
spring tension.
The heart of the
GRWB is the Ledex Size 7S, Model H2809-027 with 17.5 inch pounds of
starting torque. The GRWB and GRW are shown at the right for comparison.
GRWB: $259 GRWB-D:
