Richard,

    Thanks for the kind words about my Taig site. 

    The problem with the vee cutters is that the tip's sfpm drops to
    zero at the center of the tool. You want the thing spinning as fast
    as possible. They do remove more material because of the shape. I
    find that 90 deg cutters hold up a whole lot better than 60 or 30 deg
    vee tools. Also get them with the biggest tip radius possible for
    your design. 

    They do make burrs too, due to the zero rake angle of the cutting
    edge. You could try using small ball end mills if your work can be
    designed around a radiused groove. They are much freer cutting. I
    have though of using the 1/4 round vee bits but figure they will snap
    just from me looking at them. 

    I'm just glad I'm not the only nut trying this sort of work. 

Nick
