Pinewood Derby Axel Alignment Computer

This page contains a JavaScript program that calculates axel alignment adjustments for Pinewood Derby cars. The alignment calculations are based on the results of four trials as described in the Alignment Process chapter of Stan Pope's excellent book Learn to Build a Winner - A Textbook for High Performance Pinewood Derby Car Design and Construction. To use the alignment computer run the four trials and enter the wheel positions as they appear at the end of each trial. The recommended actions are displayed in the bottom panel.
