Welcome!!! In this episode of the Go Kart Build I build a simple hub to hold the brake rotor but I do it using a complex machine. I saw this as an opportunity to show how a keyway can be cut using a hydraulic keyseater. It is overkill for this small part but that is what I do! I hope you enjoy and don't forget to subscribe.<br /><br /><br />You can follow me on instagram @brockofawesomeness<br />...<br /><a href="https://www.youtube.com/watch?v=RRAbmb44URg" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=RRAbmb44URg</a>
