I need some bearings for the blade guides and fortuitously came across a skateboard (kids grown up & left home) while putting stuff out for our annual council clean up – nice.

Skateboards have 2 bearings per wheel so I now have a set of eight – how many do I need?

For each guide I need two for guiding the blade and…thinking about it decided to use two for thrust – that 4 per blade guide assembly x 2 equals 8 – perfect.
