Homemade lathe keyway broach electric slotter

[@2steelshells]

You are to kool for school!thanks for doing all the thinking.👍

Though unlikely to copy your build it expands my sense of possible problem solving. Thanks.

[@tommo033]

Excellent idea, it solves all the problems. You are a man after my own heart, I love building stuff out of junk and would rather build something than buy it. Thanks for posting the vid.

Very ingenious. I just added power reciprocation to a Harig 612 surface grinder using the same idea to convert the rotary motion of a motor to the longitudinal motion of the grinder, and guess what? I purchased a second set of the ball swivel rod ends from McMaster in case I might ever need them!

Nice!

Great, I like the way you did that, show us what you made, the important parts and to hell with the other 27 minutes of a half hour video with you drilling a hole, milling a surface or tapping a hole, if you have a lathe or a mill you probably already have done those things.

Great job. We shared this video on our homemade tools forum this week :)

Nice solution. How is the depth of cut and how long does it need to cut all slots?

[@phildiver2225]

Hi, the depth of cut is about 0.001" or 0.005mm each time i move it, and I normally let it do 3 passes of each cut each time i move it.

[@TorteTS]

@@phildiver2225 Thank you.

[@phildiver2225]

Oops, I meant to say 0.05mm.

[@johncooper4637]

That is a wonderful way to make a keyway but how do you hold your chuck steady and index it?

[@phildiver2225]

Hi, I didn't need to hold the chuck to cut a keyway, however I did make a simple indexing tool which can be seen at this link.
