| Rounding bar ends - how? |

I know how to make neat rounded ends to a bar, if it has a hole near the end, that will serve as a pivot point, so you can swing the bar around touching an end mill. These were made like that. But letīs assume there is no hole near the end. How could I fix the bar then? Suction cups (hehe...)? Two needles (on top and below)? Or do I need to build some sort of a jig? If so, what sort of a jig? :doh: |

I use a jig similar to this sketch. Two or three grub screws to hold the work piece and the pivot pin as close to the end as possible. This will allow various radii depending on the placement of the work piece. I have not included dimensions as they will vary depending on size required. Joe |

That's a good idea, Joe. I like the 'adjustable' aspect. I use something similar, with a false rod with a hole in the end beneath the part that needs rounding off, but it doesn't allow for different radii like yours will. I think I need to make one like yours! |

Now...... That`s a great idea! :clap: Thanks Joe. :thumbup: David D |

75Plus: Thatīs it! :clap: :clap: :clap: Exactly what I was after, just couldnīt figure out how to get there. Grub screws on both sides of the slot, and you could center the workpiece for various widths. Pivot point very near the apex of the vee... Iīm going to start today, and post pictures when done. Thank you! :nrocks: :wave: |
