    Thanks Shed.
    You’re reading it correctly.
    TBH I struggled a bit with with the setup, and was definitely grinding away from the cutting edge rather than into it.
    A lot of that was my tooth rest arrangement being less than ideal, and I think the 10mm cutter is really too small for indexing that way.
    I spent a bit of time last night making a new sleeve with a better fit in the workhead, and a larger retaining collar with indexing slots like BC showed earlier.
    I just need to cut the slots now to finish it.
    Should make the indexing easier and will allow me to use the other side of the wheel so I’ll be grinding into the edge.

    Finished off the indexing collar, then found I didn’t have enough clearance to get the index finger set up. Made up a rough holder so I could mount it higher - the same index finger I used previously slides up inside the bore.




    Was going to have a crack at this roughing endmill I buggered last year as it’s a decent size to learn on and I can’t make it any worse that it is now - but after cutting the end off with the angle grinder I realized that it’s obviously not going to fit in the ER20 holder




    So had another play with drill faceting.
    Angles aren’t right but I was happy with how the indexing worked and the finish.
