Hi JRock
I am not great at making videos myself but I would like to give you some feedback as a watcher of this video.
When talking and having the lathe motor running made it difficult to hear you explain what you were doing. Also it would helpful for those that haven’t tried rotary broaching to have an explanation on the angle of the tool entry to work piece and how the wobble of the tool cuts as it passes through the component being machined. Rotary broaching is quite difficult to get your head around if you have never seen the cutters small movement while both the tool and work piece rotate. I thank you for posting as this is a very interesting subject with many uses and very difficult in my opinion to explain how the process works.
I look forward to seeing more of your videos and no offence is intended with the feedback.
