Assembly upside down and 
lay it onto the bed so that 
these bolt heads lay in 
those recesses. Looking at 
the bed in the orientation 
above, the Front Frame 
Piece should be towards the 
top. Notice that each Y Axis 
Bearing Plate has three 
small holes left. Line these 
holes in the plate up with 
the small pilot holes. Slide 
an M5 washer onto the 
wood screws, then begin to 
thread it into the holes. Do 
not tighten the wood 
screws down until you get 
all the screws in both 
bearing plates (six total, 
three in each plate). 

Check

 

as you tighten the screws 
down that the bed flushes up 
to the front of back Frame 
Piece. It should not be 
canted or twisted. 

After you

 

finish mounting the bed, flip 
the Y axis assembly back 
over and slide it back and 
forth to ensure that the 
motion is smooth. If not, 
either the eccentric spacers 
are too tight or the bearing 
plates were a bit cocked 
relative to one another 

  

when you torqued them down tight. 

 
 

 

Z AXIS BEARING PLATE ASSEMBLY 

 

We will now assemble the Z Axis plate. This is the plate that will carry your router or spindle 
up and down. The diagram to the below shows the FRONT of the Z Axis plate. Notice that the
