Model
GRM
|
Description
The GRM is a full motion
mechanism specifically designed for the Freedom Pinewood Derby track made
by MicroWizard. It operates by remote control to start your race with nobody
near the track. The actuating component is a rotary solenoid which pulls
the Freedom's peg bar by a brass pull rod.
You will be removing
the two springs from the Freedom gate, and also you will remove the gate
lever from the side of the track. That is the extent of modifications required.
|
Two auxillary
pieces come with the GRM to allow installation without the need to drill
any holes.
|
|
The GRM is unique in
that it mounts with no fastener devices.The two aluminum rails fit precisely
into the contours of the track, and the ends are trapped by the gate and
the upper joining bar. It's a beautiful fit for a beautiful track.
|
One piece anchors the
brass pull rod to the peg bar by means of the screw forming the peg for
the left-most lane. The other piece anchors the spring to the peg bar by
means of the peg for the right-most lane. The other end of the spring is
clamped to the edge of the track downhill from the gate.
|
 |
Mount the pull rod bracket
under the two right-most gate pegs as shown.
Install the solenoid
assembly uphill and against the gate assembly. You will need to temporarily
loosen the mounting screws of the gate assembly and the top cross bar.
|
|
 |
You will
need a needle-nosed pliers to form the loops in the brass pull rod. |

One often requested
modification is the ability to trigger the light tree from within Derby
Management sofware in addition to the standard infrared remote control.
When the light sequence gets to green, the Light Tree in turn activates
the gate. This modification involves work on the Light Tree, the Gate, and
and the interconnecting cable, and adds $20. Order the GRM-E at $199 and
the Light Tree Model LT3-E at $179.
