D. 

OFFSET EDGES  

 

If the side piece edge is not aligned with the 
front or back piece edge, the edges are 
offset. See Figure-15.  
 

Cause:

 The side stops are not set correctly.  

 
Remedy:

  Measure the amount of offset on 

the two test pieces and adjust the front side 
stop accordingly. The front side stop must 
be offset from the top side stop by the exact 
width of the fingers on the template you are 
using. Ensure that the front side stop 
remains square to the work-piece mounted 
on top of the jig.  

 

Figure 15 shows offset edges 

 

D. 

FIT TOO TIGHT OR TOO LOOSE 

  

If you find the fit to be about right in every 
other aspect, but it is simply a little too tight 
or too loose, the depth of the router bit is 
probably maladjusted. 
  

1.  If the fit is too tight, decrease the 
protrusion of the router bit from the 
base.  
 
2.  If the fit is too loose, increase the 
protrusion of the router bit from the 
base.  

 

 
E. 

UNEVEN FIT  

 

If the side piece fits either excessively or 
protrudes at on edge and not the other, the 
fit is uneven. See Figure-16.  
 

Cause:

  The fence is not parallel to the 

edge of the work-piece or the template is 
not parallel to the edge of the work-piece. 
 

Remedy:

  Adjust the fence or template in 

the desired direction until it is parallel to the 
edge of the work-piece. For the highest 
degree of accuracy, clamp the two work-
pieces in the front of the jig so they are 
positioned against the two side stops and 
measure the distance between the edge of 
the work-piece and the edge of the fence or 
template.  
 
Adjust the fence or template so the 
measurement on the other end of the jig 
equals the first. Recheck the first 
measurement in case it changed during 
adjustment.
