How To Use the Slotting Tool To Cut New Slots In Your Pinewood Block

Pinewood Derby Axle Slot Tool

Pro Body Slotter

Now you can cut accurate axle slots in a pinewood derby car block with this tool and a standard hack saw. New axle slots are needed if the existing slots were not cut straight or if you want to alter the wheelbase of your pinewood derby car. You can also cut slots in the top of the block then cut the block in half to make two blocks.

To use the Pro Body Slotter, you will need:

  • Hack saw
  • Extra hack saw blade
  • Vice or "C" clamp
  • Square or other right edge tool
  • Pencil

It is best to cut axle slots before you shape your block.

Instructions

Test fit the tool

1. Test fit the tool on the bottom of the block with the two "ears" positioned on the side of the block. If the tool will not fit onto the block, use course grit sandpaper to reduce the width of the block until the tool fits slightly loose.
Draw a reference line

2. Using a square, draw a straight line on one side of the body block (opposite of the holding screw) in the desired axle slot positions for both front and rear axle slots.  Extended wheelbases should be positioned no less than 5/8" from the end of the block to prevent the wheels from extending past the ends of the car.
Position the tool

3. Position the tool on the bottom of the block with the two "ears" on the sides of the block. Align the index mark on the tool with the line corresponding to the location of the new axle slot.

Clamp the tool
4.Clamp the tool in place by tightening the 3/32" set screw with the provided hex wrench. Tighten it just enough to hold the tool safely in place (do not over tighten). The set screw will make a small dimple in the block that will be hidden behind the wheel but can be easily filled with a dab of wood putty.
Add second saw blade
5. Install two blades in a standard hack saw frame in opposite directions (teeth forward in one and backwards in the other). We recommend 24 teeth per inch for a good cut and proper width.
Cut the slot6. Place the block in a bench vice or clamp it to a table to help hold it during the cut. Cut until the blade reaches the bottom of the tool's slot.
Final Result

You now have a perfect axle slot.
