Fitting a collet chuck to a lathe:

To mount a collet chuck to your lathe it is necessary to add a backplate. Machining the backplate is best undertaken on your lathe to achieve maximum accuracy. To do this, secure the back plate to the spindle. Skim across the face to ensure squareness, then machine a spigot to match the register of the collet chuck. It is necessary to measure the PCD of the fixing holes in order to secure the chuck to the backplate.
