The Pro Body Tool reduces friction! By correctly
placing the axles in the body, a builder will not have to bend
or tweak the axles to get the car to run straight. In all cases,
if an axle needs a slight bend to correct alignment the axle placement
is incorrect and the bent axle jeopardizes correct axle to hub
alignment. Although it has corrected the alignment issue, it has
more than likely created a slightly higher friction between the
axle and hub.
This tool easily places the axle holes perpendicular
tot he centerline of the car and ensures parallelism in the
axles front to rear. This helps insure correct tracking of
the car and aids in alignment.
Test fit the Body Tool on the bottom
of the pinewood derby block with the two 'ears' positioned
on the sides of the block. If the tool will not fit , use coarse
grit sandpaper to reduce the width of the block until the tool
fits snuggly. If the tool is loose, tighten the fit by placing
a piece of paper - folded as needed - between one 'ear" of
the tool and the block.
To create pilot holes in axle slots - Use a square to draw a
straight line on one side of the car starting at the middle of
the axle slot and extending to the top of the car. (Or measure
the distance from one end of the block to the middle of an axle
slot and transfer that measurement to the top-side of the block.
Then use a ruler to draw a line from that measurement to the
center of the axle slot.) Repeat for the other axle slot.
To create new axle holes - Measure and mark
the desired position of the new axle holes on one side of the
block. Extend the mark from the bottom of the block to the top
of the block using a square (or measure and mark near the bottom
of the block and near the top of the block, and then join the
line with a pencil and ruler). Holes for extended wheelbases
are typically positioned 5/8" from the end of the block.
Repeat for the other end of the block.
Position the tool on the bottom of the Pinewood Derby car with
the two 'ears' on the sides of the block. Align the index mark
with the line on the block. Clamp the tool in place.
Hold the block firmly. Position the drill bit in the hole and
slowly drill 3/4" into the block. Without releasing the clamp,
turn the tool and block over and drill the second hole. Repeat
for the other two holes.
