Help with tapered holes

[tinmanpk59]

Have tried your idea out in VCarve, its a nice one but takes too long to generate the hole. And my machine will not take a massive ramp up in speed and feed rates to reduce the cycle time to a respectable level. Pity because I like this approach. Thanks for the input.

You can put less lines in I copied 400 times for a 12mm end mill to give you a superfine finish less would be quicker, play around until you find best to suit your setup.
Plug in "chamfer" only works in V9 I think.
