Draw Tube Assembly

The draw tube assembly comes attached to the locking
yoke and connecting rod.

To install the draw tube assembly into your lathe, do
these steps:

1. Remove the locking yoke and connecting rod from the

draw tube assembly by unscrewing the setscrews that
connect the locking yoke to the bearing housing.

2. Slide the draw tube assembly (Figure 10) all the way
into the outboard spindle until it engages around the
hub adapter

3. Place a collet in the collet adapter, so the collet
threads are exposed out of the back end of the collet
adapter, as shown in Figure 11.

The draw tube threads may be sharp. To avoid cut­ting your hands, use a clean rag or gloves to rotate
the draw tube.

4. Insert the collet and collet adapter into the draw

tube on the front spindle. While holding the collet
with one hand, turn the end of the draw tube
(Figure 12) clockwise 5 to 8 complete revolutions
with the other hand, to thread the collet onto the
spindle.

5. If the collet will not thread onto the draw tube,
adjust as instructed in Rough Adjustments, on Page

Main Adjustments

It is essential to make the following adjustments to the
collet attachment so it works properly.

To adjust the collet attachment, do these steps:

1. Insert a piece of metal stock that is sized to fit your

installed collet.

2. Disengage the hub locking pin (Figure 16) by pulling
the pin out and turning it so the flat part of the pin
is turned toward the outer rim of the adjusting hub.
The mechanism that locks the collet is depicted in
detail in Figure 17

3. Turn the adjusting hub in or out so the collet locking
pawls align properly on the flat surface of the cam
lobe (see

4. Turn the adjusting hub clockwise until you start to
feel resistance in the adjusting hub.

Figure 18).

6. Turn the two 30mm collars clockwise on the draw
tube until they contact the shoulder on the threaded
portion of the cam lobe, as shown in

Figures 19 &

20. Figure 19 is shown without the 30mm collars to

more clearly show the cam lobe shoulder.

7. Tighten the set screw on the outer 30mm collar to
ensure the locking pawls stay in place.

Note:

If you do not make this adjustment, the lock­ing pawls could fall off the cam lobe when the lever
is engaged. If this should happen, use a screwdriver
to raise the locking pawls back onto the cam lobe.

8. Engage the lever and see if the workpiece moves.

9. To tighten the workpiece more, disengage the lever.

10. Pull the hub locking pin out (see Figure 21). While

holding the pin with one hand, rotate the adjust

­ing hub clockwise with your other hand until the pin
engages into the next hole on the hub adapter.

Removing 5-C Collet

To insert a work
current 5-C collet capacity, you will need to remove the
collet and install one that fits the new workpiece.

To remove or replace your 5-C collet in the collet
attachment assembly, do these steps:

1. Disengage the hub locking pin so the flat part of the

pin is turned toward the outer rim of the adjusting
hub as shown in

2. To unthread the collet, rotate the draw tube coun-

terclockwise, in the location shown in

piece that is thicker or thinner than the

M1021 Quick Change Collet Attachment

5. Insert a brass rod through the outboard end of the
spindle and tap it against the collet adapter. Catch
the collet adapter with your other hand.

6. Tighten the outer jam nut against the cover.

Note: You can uninstall the rest of the collet attachment

by removing the hub adapter, unscrewing and removing
the replacement mounting post, reinstalling the original
mounting post, and closing and securing the cover.

Rough Adjustments

The Model M1021 is adjusted properly when the locking
pawls are tight on the cam and the workpiece will not
twist in the collet. Figure 18 on Page

2. Pull out on the lever and back the draw tube assem-

bly away to access the hub adapter.

3. Turn the hub adapter in a clockwise direction if the

Maintenance

The Model M1021 Quick Change Collet Attachment is
essentially a maintenance free tool;
to keep in mind are:

• Make sure that all the components of your collet
attachment are assembled correctly, according to
this manual.

• Once the replacement mounting post and hub adapt-
er are installed, they will not need to be removed.

however, some things

• Ensure that your locking mechanism is working prop-
erly before you start any projects on your lathe.

• Check for proper placement of locking pawls on the
cams.

• The bearings are non-serviceable. If you have prob-
lems with your bearings, you must order a new
bearing pack.

• The hub adapter must be removed in order to
change gears or access V-Belts.

• Make sure threads are kept clean and oiled to pre-
vent binding and rusting.

MAKE SURE that your machine is
unplugged during all maintenance pro
cedures! If this warning is ignored, seri
ous personal injury may occur.
