Introduction:This tutorial assumes that you know how to safely operate your power tools. Always refer to
manufacturer instructions if you are unsure how to use your tools.
Any wood worker needs to take a board from
lumber yard or their local sawyer and make this board a uniform thickness, length and width. This board needs to have all four edges square to each other. This is referred to a milling a board four square and is a pre-requisite to any wood working project.
This is best accomplished by using a jointer, thickness planer, miter and circular saws and a table saw. In this example we will mill a board 30" x 4-1/2" x 5/8" with all for edges square to each other.
Step 1: Rough cut your stock
Rough cut your stock to 30-3/4" x 4-3/4" and maintain
same overall thickness. Start by selecting a piece of stock larger then your finished size (obviously) and use a framing square to square off one end of
board. Be sure
end isn't checked (cracked) and if it is square
board off just beyond where
cracks end.
Make
cut using a circular saw being careful to make a fairly square cut. Now measure 30-3/4" and square off
board using your framing square make
second cut
same way you made
first. Be careful to cut on
waste side of
line.
Step 2: Rip to rough width
The table saw is
best tool for this cut. Set
rip fence so it is 4-3/4" from
blade and set
height of
blade so
gullet of
teeth is
same height as
stock. Following
directions included with your table saw start
blade and make
cut, being sure to use a push stick.
Step 3: Truing one face
Now that your piece of stock is
rough size needed it is time to true up one face. This is best accomplished with
jointer.
As always with
jointer it is advisable now to take more than 1/16" per pass. Taking more wood per pass will overwork
machine and give results that are less than optimal.
Analyze
board to determine
direction of
grain and whether there is cupping. It is best to place
cupped face down since it will site better on
jointer table. Run
board through for a couple of passes until you have a uniform face free of voids and dips.
