    Damaged thread repair tool

    Hi,
    I recently made this little tool for chamfering damaged threads on drive shafts where they have been hit with a hard hammer when installing, (never by you or me of course!). It can also be used for any size or type of thread from 1/2" to 1" in diameter, or even plain bar for that matter. It works well in the tailstock of the lathe, should you ever find the need to use it there.
    I have used a single triangular carbide lathe tool tip as seen in the video and it cuts with just minimal chatter.
    Not difficult to make if you have lathe and milling machine facilities and are prepared to do a bit of old fashioned filing !

    Yes, and a miniature version of this, mounted in a Dremel, would be ideal for deburring/chamfering small screws after sawing to length.

    Loved the vid, and the tool. Lots faster than a tread file.
