Re: pic: Homemade Keyway Broaches
If I get access to a manual lathe with a three jaw chuck then that will be my next project...

Re: pic: Homemade Keyway Broaches
One year at GLR we had to put a keyway into a sprocket, and we didn't have a broach or a press in the pits. So we taped about 5 hacksaw blades together, and slowly cut the keyway into the sprocket. Took awhile, but worked out just fine.
It also cost us 5 hacksaw blades. |

Re: pic: Homemade Keyway Broaches
Here is a photo of what else I did. I keyed two of these hubs as well as cutting a key slot in the drive shaft with a Dremel carbide cutter. Took a while, but it works!

Re: pic: Homemade Keyway Broaches
I've actually done this same thing but to make a knurled surface.
Grind off all but one flute, put the tap into a vertical mill and make a pass on your piece (cutting along the side, obviously). Rotate the piece 90 degrees in your vice, and make a pass again. It'll leave you with a nice knurled face that's good for gripper jaws on end-effectors. |

Re: pic: Homemade Keyway Broaches
I love that idea and it gives a good use to old taps!
