When you need to cut multiple lap joints with uniform spacing, reach for our Cross Lap Jig. Screw it to your miter gauge and use it with your table saw and a dado stack to cut the half-lap joints for anything with a wooden grid: lattice, wine racks, grilles/mullions for glass doors, and torsion boxes for your workbenches and table tops. The jig's indexing key is width-adjustable for stock ranging from 1/8'' to 3/4'' wide. The distance from the indexing key to the blade determines the spacing of your grid, and is easily adjustable with the ergonomic knobs. Simply make your cut, push the key into the kerf you just made, then make the next cut.


  • Machines the interlocking dadoes for cross lap or half-lap joints
  • Great for latticework, wine racks, torsion boxes, shoji screens and more
  • Indexing key for fast, repeatable cuts, and precise spacing in fixed increments
  • Width of indexing key is microadjustable for stock from 1/8'' to 3/4'' wide (to match width of dado)

Can this jig also be used to make finger joints or box joints? It seems like it would work for them as well.

andy v on Aug 9, 2018
Can I download the calculator for the lap jig?
Gdocanndoc G on Aug 9, 2018
BEST ANSWER: The cross lap calculator is currently hosted online only.
Is the jig fence replaceable? It seems it would not take to long to fill it up with notches.
Duane H on Aug 12, 2018
BEST ANSWER: We do not sell replacement fences. However, there are instructions and dimensions to make a new fence in the product manual.

Our Rockler T-Slot Cutter Router Bit - 5/8" Dia x 3/16" H x 1/2" Shank (Item 26099) will provide the correct slot for this jig.
Does this jig require a dado stack or can it be done with a single blade and multiple passes?
Brian B on Oct 14, 2018
BEST ANSWER: A dado stack would seem absolutely necessary for uniform width and spacing for each successive half-lap cut. It's not obvious to me how -- after making a single-blade cut -- you would accurately slide the unit to widen the cut further with multiple passes.
Am a newly woodworking. For scale from 1 to 10 how hard is this item to use?
Ruben F on Nov 6, 2018
BEST ANSWER: At 5. Actually a walk in the park.
Can this jig be used for other than pure perpendicular joints?
Jim R on Aug 13, 2018
BEST ANSWER: The simple answer is "yes" but bear in mind that if you notched each piece in an identical manner (as you would for a square 90-degree grid), you would end up with a parallelogram after assembly.
