Trying to make a precise register for an ER32 collet chuck backing plate

In this video I try to turn a very precise register on the backing plate I'm making for a cheap Chinese ER32 collet chuck. I am trying to make some money for my youtube hobby, through the Banggood affiliates program. Follow the link below, buy something you NEED and I'll earn some commission. Doesn’t cost you anything extra, and you' basically save money out of Banggood' s hands :) My fav Banggood tool: https://bit.ly/2AUgjZ7 ER32 Collet chuck: https://bit.ly/2Dt8zQ4 20mm Boringbar: https://bit.ly/2yZ4hMl The Rolingmetal photo album: https://photos.app.goo.gl/YW7rDL8YYYU...
