Each group of workpiece materials has an optimum set of tools angles which have been developed through the years.
Turning tapers on a lathe
Though it might appear that the angle is not critical the diameter at the top of the column and the diameter at the bottom will only be right if the angle is right. If a bearing that will be used is fitted to the spindle after the outside of it has been turned then this can be used for holding the spindle when the taper is being bored. These can be very long and yet quite thin. The principle of this compound slide is that axis of work piece rotates parallel to the axis of bed and the cutting tool moves at the desired angles.
Can use on external and internal. In such cases we can find out the number of mm divisions by the formula. It is fiddly work and takes some practice.
The steady is fitted on the workpiece at the required spot and clamped in place. They can also be made by using a special drill.
For example if it is necessary to drill the end of a thin taper, for example, a stanchion, trixbox configuration guide pdf a stead can be made by drilling a hole in a thin piece of steel that be held in a quickchange toolholder.

Often this means that for a given length of taper the workpiece will have to be longer than the final part so it can be held. The arms of the fixed steady are adjusted so they just touch the workpiece. One might have assumed that the angle on each size of Morse taper would be the same.
Field and maintenance shops generally use a lathe that can be adapted to many operations and that is not too large to be moved from one work site to another. This MiniLathe taper attachment is shown here from the user's perspective.
Of course the male and female tapers must be the same size to work properly. This does mean that the workpiece has to fit inside the spindle. Or, a boring head mounted in the tailstock may be used to provide the offset. It has the benefits that no special equipment is needed and very long tapers can be produced. Regardless of the size, pins used the same angle of taper for the whole range.
Because of these features tapers are used extensively in engineering. Some tapers that are ornamental might also be fluted. Must work between centers. When copying a Morse taper it is essential that the size of the taper being copied is the same size as that being made.
Or a simple gadget may be made that mounts in the tailstock chuck which allows offsetting a ball center. It would be a bit optimistic to think this will work on the first try. These centers do not point at each other as they should and so compromise accuracy. On the oboe it is conical. Here is a view after adding struts to stiffen the attach scheme.
In this method both longitudinal and cross feed can be used. The angle can be set using slip gauges.

The angle of the rotating slide is calibrated so it is quite easy to change the angle and make another, different taper on the same workpiece.
