Tools

The Pinewood Derby Tools that Derby Worx manufactures are designed to help parent and child teams work together to build a Highly Competitive Racer and learn the fundamentals of friction reduction, alignment and simple physics.  On these pages we want to share some of the more advanced tips we have learned and developed over the years to better help all racers.

PRO HUB TOOL:   For maximum performance with your Pro Hub Tool we recommend polishing the pins on the tool like you would your racing axles. By placing the tool in a large drill or drill press, start with 600 grit sand paper and work through a minimum 2500 grit or even a 1 or 2 micron polishing cloth then finish with your axle polish for a mirror finish.  The Pro Hub Tool is also  an excellent tool for burnishing in the graphite in your wheel bores and by adding a small amount of graphite in the dished end of the tool, graphite can be burnished into the inner hub face after coning for even more friction reduction

PRO BODY TOOL:  A pinewood derby car body block is not a perfect piece.  As nice as some blocks look, they are still cut or planed wood and are not parallel front to back, this creates a problem when drilling straight axle holes not only left to right, but getting them parallel front to rear.  For maximum performance and precise alignment, choose one side as your reference side, all of your marking and squaring of the Pro Body Tool will be done from this side for greater accuracy. Next, using a full sheet of medium grit or 220 sand paper on a flat counter top or a old piece of safety glass, long sand the body block reference side flat and true, mark your axle hole locations or  the reference line for the existing slot. Firmly square your tool against the trued side of the body block while carefully align your reference mark and clamp in place to drill. A folded piece of paper can be added to the opposite side to reduce any tool gap and help with squaring the reference side.  After drilling the rear axles first, slide the tool to the front, re-square, clamp and drill.  This simple technique will insure you that your holes are perfect every time and all you need is a hand drill (cordless or corded) and  the provided #44 drill bit.
