Project
Intro
Skill Objectives
• Stock Preparation
– Jointer
– Surface Planer
– Table Saw
• Joinery
– Finger Joint
– Rabbet
– Dada
– Sliding Dovetail
Paper Work
Due Date: April 20th (4 weeks)
• Start Timesheet – 3/20 ‘Planning’
• Complete Bill of Materials
• Start Procedure Sheet
– Very Important because of the NUMBER
of Parts
Parts List
•
Three Parts List Tables on the Shop
Drawings
– Upper Right Hand Corner
1. Drawer Assembly Parts List
2. Box Assembly Parts List
3. Box Lid Assembly Parts List
1 BF = W x L x H/144
• ALL MEASUREMENTS MUST BE IN
INCHES
• W  WIDTH ACROSS THE GRAIN
– Always 1st Number
• L  LENGTH WITH THE GRAIN
– Always 2nd Number
• H  THICKNESS OF THE WOOD
– Always 3rd Number
– If there isn’t a 3rd Number it is ¾”
Board Feet
• You MUST use the ROUGH DIMENSION
when figuring COST
– You need 1” thick material to get ¼”, ½” or ¾”
thick stock
• Basic Rules of Thumb:
– Add ½” to the WIDTH
– Add 2” to the LENGTH
– Add ¼” to the THICKNESS
DEPENDS ON
CONDITION OF
LUMBER
Example
• Finished Dimension: 3 ¾” x 16” x ½”
• Rough Dimension: 4 ¼” x 18” x 1”
W X L X H/144
4.25” x 18” x 1”/144
76.5”/144
BF=.53125
WOOD = MAPLE
.53125 X $3.10 = $1.65
Remember
• Use ROUGH DIMENSIONS
• Double Check the NUMBER of
Parts
• Double Check you are using the
CORRECT price for the Wood
–You will have more than 1 wood
type

Finished Dimensions
• Cutting ALL of your pieces will be like a
JIGSAW puzzle
– Best USE of material
• I will review and give instructions to EACH
student BEFORE you start RIPPING or
CUTTING anything!!
– Reduces Mistakes and wasted MONEY
Joinery Layout
• Once ALL pieces are CUT to the EXACT
Finished Dimension
• Label EVERY Piece
– Name
– Best Face, Top, Bottom, Left, Right, etc.
• Begin Laying Out ALL joinery
– Rabbets, Dados, Grooves, etc
– Finger Joints, Sliding Dovetails
Procedure Form
• EVERYONE MUST complete the
Procedure Form
• Each Step needs to be SIGNED OFF by
Mr. Thuman

Day 6, 7 & 8
-Cutting Finger Joints
Objective
• Understand BASIC
concepts of Finger
Joint Layout
• Understand use of
Finger Joint JIG
• Cut Finger Joints
using Table Saw
Finger Joint
A finger joint or box combing or box joint
is a woodworking technique used to join
two pieces of wood at right angles to each
other. It is much like a dovetail joint except
that the pins are square and not angled
and usually equally spaced. The joint
relies on glue for holding together as it
does not have the mechanical strength of
a dovetail
Use and Benefits
• Case Joinery
• Drawers
• Anything that needs
to be joined at 90
degree angles
•
•
•
•
•
•
•
Strength
Simplicity
Decorative
Speed
Good in Compression
Good in Shear
Bad in Tension
Finger Joint Layout
• Equally Divide Width
of Work Piece into an
EVEN number of
Fingers
• Depth of Joint equals
Thickness of Work
Piece
• Width of Finger is
determined by
Strength or Aesthetic
Good and Bad
ALL
EQUAL
Sliding Jig
• Holds Stock Vertically
– To Mill End Grain
• Correctly Spaces
Finger Joints
• This one makes
ONLY ½” wide Finger
Joints
• Any stock used must
be EQUALLY
DIVIDABLE by ½”
Fence
Blade
Cover
Indexing Pin/Stop
Runners
Stop – prevents
cutting through entire
Jig
Use of Jig
First Cut –
Stock Against
INDEX PIN
Second Cut –
previous cut
fits over
INDEX PIN
Completed Joint

Day 9 & 10
-Cutting Sliding Dovetail
Sliding Dovetail
• Method of joining 2
pieces of wood at 90
degrees
• Creates a Structural
AND Mechanical
Connection
• Can only be pulled
apart in 1 direction
Tools Needed:
• Hollow Chisel
Mortiser
• Band Saw
• Chisel
• Square
• Hammer
1st Step
¾”
• Use HOLLOW
CHISEL MORTISER
to make a SQUARE
MORTISE across the
BACK face of the
DRAWER FRONT
• CENTERLINE of
MORTISE is ¾”
from EDGE
2nd Step
• Cut PIN on both
DRAWER SIDES
• Use Layout JIG for
SHOULDER MARK
• Use Layout JIG for
CHEEK Depth
3rd Step
• Use BANDSAW to cut
PIN
• Cut from Outside
Corner to CHEEK
DEPTH mark
4th Step
• Using PIN as guide,
trace the angles onto
DRAWER FACE
• Use a CHISEL and
SLOWLY angle the
cheeks of the square
mortise
5th Step
• Patience
• Take you TIME and go
SLOWLY
• You want it to be a SNUG fit
