3.
Use a wrench to loosen the drawbar about ½ turn.
4.
Tap the top of the drawbar with a soft-faced hammer to disengage the
taper.
5.
Hold the tool with one hand to prevent it from dropping, and unscrew the
drawbar. Remove the tool.
To install a tool into the spindle:
1.
Put the drawbar down through the spindle from the top.
2.
Put the tool up into the spindle and thread the drawbar into it.
3.
If you have an R8 spindle, rotate the tool until the locking pin engages the
slot in the side of the tool.
4.
Hold the tool with one hand, and tighten the drawbar with a wrench. Do not
use the spindle lock pin to tighten the drawbar, as you will make it too
tight.
5.
Replace the plastic cap on the top of the spindle.
Squaring a Vise
When you mount a vise on the mill table, it is important that it be mounted
square to the table. If your vise is not square to the table, you will not be able
to produce accurate work.
The vise is usually mounted with the long axis of the vise perpendicular to the
long axis of the table. Thus the jaws are parallel to the X-axis of the mill.
To square a vise on the table:
1.
Mount the vise on the table and snug, but don’t tighten, the mounting bolts.
2.
Open the vise jaws at least 1”.
3.
Put the 3/8” diameter post on the top dovetail of a dial test indicator.
4.
Put the dial test indicator post in a drill chuck, end mill holder, or collet in
the mill’s spindle with the dial facing front.
5.
Move the X-, Y-, and Z-axis controls so the point of the dial test indicator is
between the vise jaws and about 1/8” below the top of the vise jaws.
