An Accurate Quick change tool holder

[Metaler]

To back up my website I have decided to produce Videos to illustrate the projects and processes it contains, starting with my Quick Change Tool Holders. These, being of an unconventional design, there appears to be a reluctance to take it up so have included in the video an explanation of the principles behind the design and carrying out tests to show the level of accuracy it achieves.

Vertical repeatability tests showed that the tool bit returned to much better than 0.0004 in / 0.01 mm and horizontally not quite so good but still within 0.0004 in.

I have already produced 22 videos but am only making them public gradually, around one a week.
