laguna 14-Twelve Bandsaw, Manual

Page: 42 / 68

bandsaw, you will probably have a good idea of the blades that are suitable for you.
If you lack the experience or are unsure of the type of work you will be doing with
your machine, we recommend that you purchase a selection similar to that listed
below, which is a good general selection and will tackle most jobs. As you gain
experience, you will settle on the blades that suit you.
1. 1/4" 6 TPI. This is a small, aggressive blade that is suitable for tight curves and
fast cutting where a good surface finish of the cut is not important.
2. 1/4" 14 TPI. This is a small, fine blade suitable for reasonably tight cuts where the
surface finish is important but speed of cut is less important.
3. 1/2" 3 TPI. This is a general-purpose blade that can cut large radiuses and short
sections of straight cuts. The cut is fast and the surface finish of the cut is poor.
4. 3/4" 3 TPI. This is a general-purpose blade, which will be used for straight cuts
and is suitable for large radiuses.
5. If you are going to be cutting hardwoods or require superb surface finish, then you
should consider purchasing a Resaw King blade from Laguna.
Rounding the Back of the Blade .
With most guide systems it is recommended that the back of the blade be rounded
with a stone. As the machine is supplied with Laguna ceramic guides, this is not
imperative because the ceramic will round the back of the blade as it is used.
However, if you decide that you want to round the back of the blade, a procedure
follows.
A round blade back creates smooth interaction between the thrust bearing and the
blade. If the blade rotates slightly, there is no sharp blade corner to dig into the thrust
bearing; also, the rounding process smoothes the weld. A blade with a round back
makes tight turns better because the round back has smooth interaction with saw
kerfs.
After the guides have been adjusted and the machine is running, hold the stone
against the back corner of the blade for about a minute. Wear safety glasses when
rounding the blade. Then, do the same thing on the opposite corner. Next, slowly
move the stone to round the back. The more pressure you put on the back, the faster
you will remove the metal. Be careful that the inside of the machine is free of
sawdust because sparks could start a fire. On small blades such as a 1/4" blade, the
pressure on the back of the blade may bring the blade forward off the front of the
wheels. Therefore, be careful not to put too much pressure on the stone. When
doing this, it is also important that the upper guides be positioned right above the
stone.
The blade has teeth and extreme caution must be exercised, as your
hands will be very close to them.
