bandsaw blades have a certain amount of "lead" (the tendency
of the blade to wander off the cutting line), depending on
the set and style of the blade's teeth. The amount of this
"lead" varies from blade-to-blade. That's why it's usually
not good enough to align your Bandsaw's Rip Fence squarely
with your blade and assume that merely pushing your workpiece
through the blade will create a straight line. Chances are
good that this simply won't be the case.
becomes most apparent when attempting to resaw thin boards
out of thick ones. For that reason, your Bandsaw's Rip Fence
is usually NOT the best way to guide a wide (3" or wider)
board through a resaw cut. There is a high probability that
your blade will wander off and you won't like the cut. If
you're planning to maintain a consistent thickness from end-to-end
when making a resaw cut, you'll save yourself a lot of time
and headaches by building yourself one of these simple jigs.
1 shows the plan for the Jig. Make it from a 5" x 6" piece
of 3/4" thick Apple Ply, Baltic Birch or similar multi-layered,
voidless plywood. When cutting it out, it's IMPERATIVE that
you maintain a 90-degree angle between the vertical face of
the jig and it's "foot".
vertical face features a "bullnose" edge that rests against
your workpiece when making your cuts. Form this edge with
Table and a 3/8"
Round-Over Router Bit passed down each side of your jig's
vertical face. Use a 1/4"
Straight Bit to cut the travel slot. That's pretty much
If you have a later model Shopsmith Bandsaw, you can attach
the jig to the table with a 1/4"-20 bolt, fender washer and
T-Nut, slipped into your Miter Gauge slot. If you have
an older model Shopsmith Bandsaw (or one without T-Slot Miter
Gauge Slots), you can merely C-Clamp it to your worktable.
If you'll be using the latter of these two approaches, there's
no need for you to cut the travel slots when making the fixture.
device has been designed with a rounded face that your workpiece
surface rests against during the cutting process. To use the
jig, first use a marking gauge or similar device to draw a
line down the full length of the workpiece's edge that will
be up (and visible to you) while cutting. This line will serve
as your guide.
simply start your cut, always holding the wide face of your
workpiece firmly against the vertical "bullnose" of the jig
as you advance your stock slowly through the cut. Watch closely
to see which way the blade "leads" as you cut. To correct
for the "lead", simply swing the end of your workpiece left
or right to compensate and keep your cut going straight down
the line. It's just that simple.
