To adjust your 5-C collet in the collet closer
assembly:
1. Choose a 5-C collet that is suitable for the
intended stock size to be turned.
2. Line up the collet keyway with the collet
adapter pin and insert the collet until it stops,
then gently rotate it for final alignment.
3. Gently push on the end of the draw tube until
it engages the collet threads in the spindle,
and rotate the adjusting hub in a clockwise
fashion (as viewed from the outboard end of
the lathe in Figure 8).
— If the draw tube fails to touch the collet,
remove the collet and look into the spindle to
see if the draw tube is accessible for proper
engagement. If the collet cannot touch the
draw tube when inserted into the spindle, see
the following section on “Rough Adjustment.”
If the collet does reach, try again to thread
the collet and adapter into the spindle by fol-
lowing the guidelines in the “Tube Assembly”
sub-section of this manual.
