    Default Important keyseat cutter consideration

    Had this emailed to me and thought I'd share it, with everyone here. Makes for some interesting reading.

    Not a fan of woodruff keys. I have seen them create a weak point on the shaft and they break there.

    Industry would like them as they are quick and easy to make. Compared to a feather key that is slower as it requires multiple passes unless the slot drill used is very stiff.

    I think I remember the late UK machinist John Stevenson saying he liked woodruff keys as they made him a lot of money repairing broken shafts.
    Gold, the colour of choice for the discerning person.

    I've had the Crankshaft keyway open up, had to have a special key made to fix it.
    My main thoughts on the article was for cutting T slots.
