Item 38142 

Table and Support Arm to Column

1.  Remove the Rack (2B) from the Column (1B) by 

slackening off the Collar Set Screw (11B) and 

removing the Collar (19B).  The rack is stowed 

in this position only for transit purposes.

2.  Lubricate the Worm Gear (18B) with light grease, and 

insert shaft first into Worm Gear Housing in the Arm 

which should fully mesh with the Helical Gear (17B).  

Hold it in this position.  The Worm Gear Shaft 

will extend through the housing to be ready 

for the crank to be attached in a later step.

3.  Gently slide the arm assembly over the column 

and hold it steady while inserting the Rack (2B) 

down through the Worm Gear Housing, meshing 

with the Helical Gear (17B), ensuring the long 

smooth end of the rack is uppermost.  The bottom 

end of the rack will be located in the groove 

formed by the column support and the column.

4.  Hold the machine in this position while replacing the 

collar on the column, and ensure that the end of the 

Rack (2B) is firmly engaged in the groove formed 

between the collar and the column.  However, make 

sure the Rack is not pinched and there is a working 

clearance between the Rack (2B) and Collar (19B).

5.  Firmly secure the Collar (19B) 

with the Set screw (11B).

6.  Thread the Arm Locking Handle (16B) in from the 

left, and tighten to secure the arm to the column.

7.  Attach the Table Crank (8B) to its spigot 

and tighten the securing screw.

8.  Slacken off the arm locking handle and turn the 

crank, testing to ensure that the arm will move the full 

length of the rack easily, without binding, and will also 

rotate about the column evenly, and without binding.  

9.  IF TOO TIGHT, Nudge up the Arm Locking Handle 

and slacken off the Collar Set Screw.  Adjust to 

give a greater working clearance between the rack 

and collar, tighten the set screw, and test again.  

10. Insert the table into its housing on the arm 

and secure with the Table Clamp (13B).

Head to Column

1.  It may be necessary to unscrew the Head Lock 

Set Screws (21A) slightly to ensure they do 

not protrude internally, as this would prevent 

the head from sliding fully into position.

2.  With assistance, raise the Head (1A) 

and locate it on top of the Column.

3.  Align the head with the base, and firmly 

secure with the Set Screws (21A).

4.  Screw the three Feed Handles (24A) and screw them 

firmly into the hub of the Spindle Feed Shaft (25A).

Installing the Chuck

1.  With the Chuck Guard lifted clear of the 

spindle nose, slide the work table up the 

column to within 6″ of the spindle.

2.  Open the jaws of the chuck to their maximum, 

using the Chuck Key supplied.

3.  Put a piece of scrap wood on the table 

to protect the Chuck Nose.

4.  Ensuring all parts are thoroughly clean 

and dry and burr free, insert the Arbor (14) 

firmly into the end of the Chuck (15).

5.  Insert the other end of the arbor, with the chuck now 

attached, into the end of the Spindle Shaft (13), 

turning, where necessary, to ensure that the 

point on the end of the arbor locates correctly 

with the drive slot in the spindle shaft.

6.  Pull the spindle down using the feed handles, 

pressing the chuck nose hard against a piece of scrap 

wood on the table, to press the chuck into place.

Pulley Cover Knob

Locate the knob with Pan Head Screw (22) 

and attach to the cover.  Screw on tightly.
