Making A Rotary Broach - Cutting Hex Sided Holes (DIY)

Описание: G'day everyone,

In this video I will be showing you the journey that I undertook to try and cut my own hex sockets. To do this I need to make use of a rotary broaching tool. There are commercial versions of this tool, but they are out of my price range for a hobby shop, so I decided to make my own. This will be a rotary broach tool for the lathe.

Making one should be a pretty straight forward job, but there are fine details that need to be done correctly in order to do this correctly. It took me a few weeks and several revisions to make this work. I hope you enjoy this video.

The two links below are well worth checking out. They provided me with a useful direction to go in when designing this tool.
