Layout of Mortise-and-TenonStart with two 2” x 11” x
¾” boardsLabel one board M and
the other TOn M, mark 1st line 2”
from one end2nd mark 2¼” from end3rd mark 3¾” from end 4th mark 4” from endDraw straight lines
across board in line with marks
Layout of Mortise-and-TenonBetween two inner
lines, mark ¼” in from each side in two places
Create lines parallel to sides of board and shade in center like picture
Layout of Mortise-and-TenonOn end of board,
mark line 1” down from top edge
On T, mark a line 7/8” in from one end
Creating the MortiseUse a machine called
a mortiserDrills square holesUse the ¼” mortise
bitTo start, clamp in
board and check board flushness to table
Setting DepthOpen clamp on left
side of machineAdjust depth of bit to
line on end
Close clamp on left side
This engages stopper for depth
Starting the MortiseCenter bit and align
to one endStart drilling
After cut, move bit about ½ the width of the bit and repeat
Drilling Process
Finishing MortiseContinue/finish to
cut mortiseAfter mortise is
complete, it is optional to clean out mortise with a small mortise
Making the TenonAdjust the blade
slightly below ¼”After blade
adjustment, set fence so the opposite side of the blade aligns with the layout line on board T
Making the TenonCut shoulders first
(on 2” sides)Use multiple passes
to cut length of tenon
Making the TenonFlip and repeatTest fit and raise
blade slowly to create tight fit
Making the TenonBy slowly creeping
up the height of the blade, a perfect fit tenon can be cut
Making the TenonAfter cutting
shoulders, cut the cheeks using same procedure as shoulders
Remember to flipCreep up on the depth
of cut by slowly adjusting height
After tenon fits, mortise-and-tenon is complete
SummaryRemember, cut the
mortise firstSneak up on the size
of tenon to create a perfect fit
By using proper layout and some of the techniques, making a mortise-and-tenon can be easy
