    Spuds

    In the context of machining, a “spud” is a pointed metal rod that is used to locate the center of rotation of a mill at a desired point on the XY plane. This point is usually the intersection of two reference surfaces and both the X and Y axes are zeroed. The spud must be mounted in a collet which requires any cutter to be removed. This article presents two tools that avoid disturbing the cutter.

    Hi Rick,
    Very clever !
    For my understanding, why "spud" ? I had a look into my dictionary and I found : potato ?

    Little comment, the last method for touch down with ohm-meter : why did you change the bit in the chuck (I thought the whole interest was not to ?)
    Thanks
    Cheers !
    Christophe

    Christophe,

    I have no idea why a metal rod with a point on it is called a spud. The term is used both for a tool to find center and also by workers to align holes in I beams so a bolt can go through. Crazy English!

    The ohm meter was used to check accuracy and is not part of normal use.

    Keep up YOUR great work. I enjoy seeing all of your inventions!

    Rick

    Hi Rick,
    This is a great idea and I can use the pointed "spud" tool for my milling work I do with my small Unimat SL 1000. I must first remove the milling cutter or spotting drill to find a new location with a pointed rod and there is never a lot of room to do the tool exchanges. Your spud tool idea is exactly what I needed for work with the Unimat.
    Thank you, Paul
