Gudgeon

Patrick's father had just bought a farm and was frustrated at having to hang 20 gates from their 'gudgeons' - the metal pin that farm gates hang from. Patrick needed a project for his school science fair and this was a perfect opportunity.

The Gudgeon Pro 4 in 1 looks like a 1.4m-long spirit level, but has holes specially placed to guide the drill to allow perfect gudgeon placement. Its length is designed to show you how far to ram the fence posts in, it has markings to guide wire placements and has levels to ensure the posts are upright.
