Table to column
1. Locate the Elevation Worm Gear (19B), the Crank
Handle (5B) and the Table Crank (4B). Insert the
Worm Gear Shaft into the Table Support and extend
the Shaft through the opening as far as possible.
2. Locate the Table Crank (4B). The Crank is to be
installed on the Elevation Worm Gear Shaft (19B).
A Set Screw (7B) is to be aligned with the flat portion
of the Shaft. Get the Crank as close as possible
to the Support, and then tighten the Set Screw.
3. Screw the Crank handle into the Table Crank.
Use an adjustable wrench to tighten
the Crank Handle securely.
4. Loosen the Set Screw (2B) in the Column
Collar (1B) with the Hex wrench and remove
the Collar and Rack from the Column.
5. Locate the Rack (6B) and with the smooth end of
the Rack pointing upward, slide it down through
the large, round opening in the Table Support (3B).
Engage the Rack into the Gear Mechanism found
on the inside opening of the Table Support.
Head to column
1. With assistance, slide the Head (45A) onto the
Column as shown in the Assembly Diagram.
It may be necessary to unscrew the Head Lock
Set Screws (15A) slightly to ensure that they
do not protrude internally, as this will prevent
the head from sliding fully into position.
chuck
1. Loosely slide the Chuck onto the Spindle. Make
certain that the teeth of the Chuck are not exposed.
2. Put a piece of scrap wood on the
table to protect the Chuck nose.
Item 39955 For technical questions, please call 1-888-866-5797.
6. While holding the Rack and the Table Support
as assembled, slide both down over the Column.
Slide the Rack down until the Rack is positioned
against the lower Column Support.
7. Replace the Collar (1B), with the bevel
side down, which was removed in Step 4.
Tighten it with the Hex wrench used in Step 4.
Note: In order for the Rack to slide when the Table is
swung to the left or right on the Column, the Collar must
sit loosely over the Rack. Only tighten the Set Screw
enough to keep the Collar in place. Over tightening
the Set Screw may result in breaking of the Collar.
8. Check the Column Collar for proper adjustment.
The Collar should sit evenly on the
Column and the Rack should slide freely
when the Table is rotated 360º.
9. Locate the Column Clamp (17B) and insert it into the
Table Support. Once inserted, tighten it by hand.
Once this is done, rotate the Worm clockwise with
the Crank. If necessary, loosen the Set Screw in
the Crank and reposition the Crank as close to the
Table Support as possible. Tighten the Set Screw.
10. Check the "gap", i.e., the clearance between the
Table Crank and the Table Support. If the gap is
larger than 1/32", crank backlash will be minimized.
2. Align the Head with the Base (10B) and firmly
secure it into position with the Set Screws.
3. Screw the three Rods (19A)
firmly into the Hub (20A).
3. Pull the Spindle down using the Handle.
Press the Chuck nose hard against the scrap
wood on the table until the Chuck is forced
into a solid fit. The Chuck is pressure fitted.
