Instructions for using Pinewood Derby Body Tool Axle Jig

The Pro-Body Tool is designed to accurately straighten existing axle slots or create new axle holes Using a hand drill on BSA and PineCar kits. The required #44 drill bit is included.

1. Test fit the Pro-Body tool on the bottom of the block with the two “ears” positioned on the sides of the block. If the tool will not fit onto the block, 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 tool and the block.

To create Pilot Holes in Axle Slots

1. 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).
2. Repeat step 1 for the other slot.

To Create New Axle Holes

1. 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 wheelbase are typically positioned 5/8” from the end of the block.
2. Repeat step 1 for the other end of the block.

Position the Tool

• Position the tool on the bottom of the car with 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 ¾” into the block.
• Without releasing the clamp,turn the tool and block over,and drill the second hole.
• Repeat steps 4 to 5 for the other 2 holes.

Technical Data for Pinewood Derby Body Tool Axle Jig

The Pro Body Tool is designed as a drilling aid to help create correctly placed axle holes on the body or correct misaligned slots in stock blocks when rules require their use.

1. The Pro Body Tool easily places the axle holes perpendicular to the center-line of the car and ensures parallelism in the axles front to rear. This helps insure correct tracking of the car and aids in alignment.
2. The Pro Body Tool locates all of the axle holes at the same height on the body which helps ensure the car is sitting square to the track, for a equally balanced car left to right and an aid in alignment.
3. The Pro Body Tool helps guide the thin #44 drill bit required to drill axle holes preventing deflection for a more accurate job. This is something that can not be done with a drill press plus due to the clearance required in the quill assembly in most hobbyist and home use drill presses to make the press work, there will most likely be some run-out in the drill chuck, this makes the Pro Body tool the most accurate choice plus only a hand drill is required for the job.
4. 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 (this is the perfect foundation for the best possible Rail Rider™. By getting the axle placements in the correct position the builder will have to make minimal adjustments to get the desired alignment and prevent “Cross-Binding” in the car. This is where it takes excessive corrections in opposite directions to get a car to run straight or be a Rail Rider™ , while the car is going in the correct direction excessive load points have been created at friction points, the Pro Body Tool will prevent this.
