Picture of Another Soap box derby build
This is another build for Trowbridge soap box derby.  These my son and I built these for 1st Westbury Cub Scouts

220 litre plastic drum
4 bicycle wheels (14" - 20" are ideal)
A pile of timber
      3 pieces 1metre long
      4  pieces 75mm longer than the wheel diameter
2x M10 bolts and matching lock nuts
M8 threaded bar
An assortment of screws and smaller bolts
15mm x 3mm steel bar for track rods, and control arms
2x 15mm equal T plumbing fittings
One standard issue 9 year old cub scout for checking sizes

Step 1: The Start

Picture of The Start
Take your drum, and drill a hole on the side near the bottom big enough to take jigsaw or padsaw blade.  This is so a the hole for the driver can be cut. It needs to be big enough to allow easy ingress and egress but small enough to keep the cub safe when they eventually crash it.
