    For setting precise angles on the compound, especially smaller ones, you could use trigonometry.
    First you set up the compound using the divider; then, with a dial indicator resting on the toolpost and touching the workpiece, you crank the compound a known distance.
    The real taper angle is two times the arcsine of the dial indicator measurement over the distance travelled.

    Gilles, I know that it's too late for this part, but I've seen other Machinists (on their "manual" lathes) using drill-drivers to turn the hand-cranks in order to get better finishes. They make up adapters between the drill-driver's chuck and the hand-crank they are interested in. This gives a more consistent rate of rotation of the hand-crank and therefore a nicer/more-consistent finish. I _definitely_ plan to do this on my lathes the next time I need to turn something! This is a _very_ interesting series and I'll be going straight to "Part 3"!

      You’re absolutely right Bob. Been eyeing them up this week. Gilles

    Also, if you take balanced cuts you will always hit your target size.

      Thanks for the advice Richard. Much appreciated

    Like you said in your video, you can always practice on the test piece before you commit to the actual part. It’s looking good so far, keep up the great work!

    Your poor finish finish is not turning fast enough and your DOC is too small for carbide insert tooling. But I like the video. Cheers
