Taper

Andrew cuts the taper in the jaws With the taper cut and the work piece clamped at full pressure

You can eliminate the need to add a taper to the jaws

It will taper each wall four thousandths of an inch (0.004 , 0.102 mm)

Let's find out just how much taper should be added to the jaw bore

To compensate for this deflection, cutting a slight taper in the jaws may become necessary

After the taper is cut and the correct force is applied to the work piece

The inverse of this, is one thousandth of an inch (0.001 , 0.025mm) too little taper

Now, let's look at what too much, and too little taper look like using our setup

This will taper the face so the bore is larger diameter at the bottom than at the top

In either case, another pass can be made to either remove or add a slight amount of taper

Now Andrew uses a slow drying bluing compound to check if he needs to make another slight taper cut

Now they are the correct bore size and once again concentric to the spindle Adding a taper to your jaws

And in proportion, what would the size of the sphere and the length, and what would the taper be to the Earth?

You should cut the taper to leave more material at the jaw tip than at the jaw base Going back to his original program

One thousandth of an inch (0.001 , 0.025 mm) too much taper results in a concentration of bluing at the base of the work piece

He finds a four thousandths of an inch (0.004 , 0.102 mm) space, so he will start by adding a 1 4000 taper to the jaws
