6.  Push the headstock back and re-connect 

the spring (Figure 13). 

You must now also shift the indication template 
(Figure 16). See “Indication Template”. 

 

Indication Template 

Because the tracer pin is not easily observed 
while the machine is in operation, the indication 
template (A, Figure 16) provides the operator 
with a visual record of the progress of the 
“hidden” tracer pin. The bracket (B, Figure 16) 
slides in and out of the notches on the indication 
template, echoing the tracer pin as it slides in 
and out of the notches on the template bar 
below.  

The pitch of the indication template must match 
the pitch of the template bar. Therefore, when 
turning the template bar for a new pitch, you 
must also change the indication template.  

1. First notice how the notches on the 

indication template are grouped toward the 
right side of the machine. The indication 
template should always be oriented in this 
fashion. 

2.  Remove the socket head cap screw (C, 

Figure 16) at each end of the indication 
template, with a 5mm hex wrench.  

3.  The indication template that came installed 

on your machine contains the 1” and 2” 
pitch. The other indication template has the 
1-1/2” and 2-1/2” pitch. Either flip the 
indication template, or replace it with the 
other one as needed, to match the pitch of 
the template bar.  

4.  Re-insert and tighten the socket head cap 

screws (C, Figure 16). 

 

Fixed Chaser 

The fixed chaser (Figure 17) provides a support 
on which the workpieces rest. The spacing 
between the “fingers” of the fixed chaser allows 
clearance for the cutter. 

The DT65 Dovetailer comes standard with three 
fixed chasers at 2”, 2-1/2” and 3” pitches. (Pitch 
is the distance between the centers of the 
“fingers”; see Figure 18). 

NOTE: If you wish to use the 1-1/2” or 2-1/2” 
pitch on the template bar, you must replace the 
fixed chaser on the machine with one of the 
others provided. Figure 18 explains how the 
available fixed chasers correspond to the pitch 
of the template bar.
