Here are the steps for Res-awn door panels of spattered maple.
1. Find the point angle by drawing a streak
parallel to one edge of a 16-in. long scrap piece.
Saw the streak freehand. Sign how much you have to
angle the wood in order to track a straight line.
This is the drift angle.
2. Stop about halfway through the cut, hold the wood
in place and shut off the saw. Trace the‐angle of the wood on the band saw bench.
3. Set your barrier parallel to the line on the table.
An adjustable block at the end of the barrier allows you to
hold this angle as you move the barrier laterally. Create sure
your table is square to the blade and your barrier is square
to the table.
4. Clamp the barrier and create a test cut. Watch
for the wood pulling away from the out feed side of the
barrier or binding. It can take a couple tries to get the drift angle perfect. Once the drift angle is correctly set, move the barrier laterally to create the cuts you need.
5. Position the barrier and re saw your board! Be
sure to use a push block and push stick to keep your
fingers well away from the action.
6. Draw a line down the middle of the log using a pencil and
straight edge, or snap a chalk line.
With the log protected into the sled, saw the log in partial.
7. Set up a barrier to re saw the boards. Run one face of your halved log against the barrier, and keep going until you've cut the entire log.
8. Position the barrier so the veneer is
being cut from the side of the board away from the
barrier. Although this means moving your barrier for each
cut, it gives the best results. Use a push block and keep
an eye open for the blade blowing out through the face
of the veneer. After your first cut, smooth the face of
the board with a planer or joint-er, and re-position the
barrier. Repeat until the piece is down to 1/2-in. thickness.
This is about as far as you can safely go.
9. Controller bearings in its place of controller blocks can help band saw blades run straighter. They price around $150, also are obtainable for virtually any saw.
10. Intermediate‐sized band saws (16 in. and 18 in.) are outstanding for re-sawing, with bigger motors, wider blades and larger tables. Prices are generally $1,000 to $1,800. When good cuts go bad.
So you've mastered the setup, but you're still having problems? Here are some tips:
a. Always use a sharp blade.
b. Keep your feed‐rate slow. Listen to your
saw and slow down if it's bogging down.
c. Use a blade with the right tooth count.
Too many teeth create it hard for the blade
to clear the sawdust.
d. Even with everything correctly
set, your wood may not cooperate.
e. Tension your blade. Too little tension can lead to barrel
cuts . The blade shouldn't deflect extra than 1/4 in.
