15mm projection of the alignment tenons 

and dowels and around 20mm of net 

support for the pivot mechanism.

The only other measurement you need to 

keep in mind is the distance from the in-

side of the end skirt to the outside of the 

outboard-most cross member.  That has 

to be more than the distance the skirt/top/

leg assembly will move when the table is 

opened up for leaf deployment.  

I like to see the two table plates able 

to move out about 30mm to 40mm 

more than half the width of the leaf.  

That leaves plenty of clearance for the 

leaf to open easily as you can see in 

the photo below.  Once the leaf is de-

ployed, you will push the two halves of 

the table together, engaging and stabi-

lizing the leaf.

Since I normally work with 20mm thick 

stock I set the centerline of the inner-

most frame cross members to be the 

width of the leaf plus 60mm (leaf width 

plus 40mm net clearance, plus the 10mm 

distance out to the center on both of the 

two cross members.

On normal size tables the frame can be 

generous in size and still leave plenty of 

room for the leaf and leg movement so 

the inside of the end skirt to the outside of 

the outboard-most cross member is not 

an overly critical dimension.

Cut a step in the ends of each frame side 

rail as shown above.  The step will allow 

the top plate part of the leg assembly to 

clear the ends and will make 

more sense when we get to 

constructing the leg assem-

blies.  

Mount the ball bearing slides 

centered down 0.5mm less 

than the centerline of the 

frame side rails.  We will 

mount the other half of the 

ball bearing slides to the cen-

terline of the skirt and that will provide for 

0.5mm (~.020”) clearance between the 

underside of the top plates and the top of 

the frame members.  Align the 

back end

of the slide with the centerline of the 

inner-most cross member as shown in 

the photo above.    Use the longest and
