G'day everyone,
One thing that I always assumed was out of the question in terms of being able to make in my home workshop would be an internal spline shaft. External splines could be done (although probably not involute) but internal splines requires sophisticated pull broaches.
However when push comes to shove, and I need a spline shaft, well I had to figure out how to make one.
The spline shaft that I make here is a 6 sided, straight faced spline. This one in particulate does not adhere to iso standards, but with slight modification, I can see this being used to broach one that does.
I do want to point out here this this is a hobby focused video. Broaching 6 keys took a very long time, and I wouldn't expect a job shop to use this, but its always handy to know this method.
I hope you enjoy the video.
