This post is by way of an introduction to an occasional new feature of the site, where I will videos to different posts to help with understanding. Adding videos is not in my skill set, so this first is just a general overview of some of the ways in which waterjets have evolved over the years. I have tried adding one before, but this is the start of a little more of a concerted effort to use this medium. The overall video runs some 15 min 39 seconds. 
It is a compilation of different tapes made over the years, some of which are now otherwise unavailable. I’m going to let the overall video speak for itself with this first piece, but will then come back in subsequent posts to discuss some of the parts of the video. I hope you find it interesting.
As I mentioned I will break this into segments and discuss those in more detail later.
