MACHINE VICE
The Model B comes supplied with a milling vice that also serves as the compound for the lathe. The 4
way tool post must be removed before using the vice. Loosen the lock handle and slide the tool post off of
the compound / vice as
Figure 14.
The milling vice can be aligned to 1 of the 2 axis of the lathe or at any angle desired. Care must be given
to setting the vice if a precision angle is needed. The following instructions are given to make the jaws
parallel to the travel of the cross slide.
1.
Remove the tool post as described above.
2.
Loosen the swivel bolts on the compound / vice so it can swivel freely. Pivot the compound / vice so
the jaws of the vice are roughly aligned with the cross slide.
3.
Mount the drill chuck into the milling spindle and secure an indicator into it or, place a dial indicator
mounted to a magnetic base on the bed as in
Figure 15.
4.
Position the cross slide and apron so the indicator point contacts the stationary vice jaw or a parallel
mounted into the vice.
5.
Move the cross slide with the hand wheel and watch the dial. Note the direction the needle is moving
on the dial and by how much.
6.
When the vice has moved so the indicator is at the other end of the parallel, pivot the vice one half the
amount of motion detected in
step 6.
7.
Move the vice to the starting position and note the difference. Again, pivot the vice one half the
difference.
8.
Repeat
steps 6
through
8
until the dial remains stationary when the vice is moved.
9.
Tighten the pivot bolts on the base of the compound / vice.
