SECTION 1 OVERVIEW
1.1 Toothsetter/Gauge (LTTSG) Introduction
There are two steps to maintaining blades used on the Timbery sawmill. They should
ALWAYS be followed in this order:
1. Blade Sharpening
2. Toothsetting
See Figure 1-1. The blades supplied by Timbery have a raker-style set in the teeth. If you
look at a blade from the top, you will see that the teeth are set (or bent out) in a repeating
sequence; straight, left and right. The teeth that are set left and right do the cutting. The
straight teeth (rakers) clear the cut of sawdust.
See Figure 1-2. As the blade is sharpened, the tip of the tooth recedes and the set
becomes smaller. Correct setting is one of the most important factors in the cutting ability
of a blade. Check used blades regularly to see if they need resetting.
The Toothsetter/Gauge (LTTSG) provided in the Blade Maintenance Package allows you
to accurately and evenly set the teeth of a bandsaw blade. The spring-loaded clamping
mechanism lets you position a tooth in front of the Gauge and clamp it in place. You can
then measure the set. The tooth is bent by clamping the blade further. This chapter
describes proper setup and operation of the toothsetter.

Deburring The Blade

1-2 TSdoc102519 Overview
1.2 Deburring The Blade
Sharpening leaves tiny metal burrs on the back side of the teeth. New blades also have
burrs. These burrs MUST be removed before the set is checked. If they are not removed,
they may cause the toothsetter to give false readings.
To remove burrs, take the blade from the Sharpener. Invert it, so that the inside of the
blade is facing out. Drag a stick of hardwood across the blade in the opposite direction
that the teeth cut. (Use the weld in the blade as a reference point for starting and stop-
ping.)
Cutting with the blade also removes burrs. If the blade you are about to set has been
used after sharpening, you will not need to deburr it. Clean the blade before removing
from the mill by running the Water Lube Option for 15 seconds. Remove the blade and
wipe dry with a rag to prevent rusting.

SECTION 2 SETUP
Mount the toothsetter to the stand. Use the mounting holes found in the base plate of the
setting fixture. Use the provided bolts (inserting the bolts down through the top of the
mounting plate), wing nuts and washers. Setup the toothsetter so that there is at least 32"
(81.0 cm) to the rear and to either side of the tool. This allows enough room for the blade
supports.
See Figure 2-1. The main components of the toothsetter are shown below. These parts
will be discussed in the following instructions.

2.1 Blade Support Installation
Attach the three blade support arms to the threaded mounting bar at the rear of the tooth-
setter.
See Figure 2-2. Assemble a blade support guide onto the end of each blade support arm.
Bolt from the hexed side of the guide assembly. Tighten the top bolts with the self-locking
nuts. Tighten the bottom bolts with the wing nuts.
The guides should be about 1" (2.5 cm) from the ends of the right and rear tubes and
about 2.5" (6.0 cm) from the end of the left tube. Final adjustments will be made later.

2.2 Dial Indicator Setup
See Figure 2-3.
1. Back the setting point out of the way. Insert the hex key in the end of the setting con-
tact point shaft and turn counterclockwise until the setting contact point is behind the front
edge of the moving clamping plate.
2. Adjust the Dial Indicator. Clamp the gauge pin between the clamping plates. The pin
should be touching the center of the gauge foot.
The dial indicator should read 0. If the dial indicator does not show 0, loosen the dial lock
on the upper right side of the dial indicator. Rotate the dial indicator to 0 and retighten the
dial lock.
Now, remove the gauge pin from the toothsetter clamp. The dial indicator should now
read between -.001 and -.005.

See Figure 2-4. If the dial indicator does not read between -.001 and -.005 with nothing
clamped, you will need to adjust the indicator mounting block:
3. Reclamp the gauge pin centered on the gauge foot.
4. Loosen the screw at the bottom of the indicator mounting block. Move the indicator
assembly back until the gauge foot does not touch the gauge pin.
5. Move the indicator assembly forward so the gauge foot touches the gauge pin and the
gauge needle moves .001 - .005. Retighten the mounting block screw. Make sure the
mounting block remains flat against the toothsetter base plate.
6. Rotate the dial face until the gauge reads zero.
7. Unclamp the gauge pin. The indicator should now read -.001 to -.005. If not, repeat steps
3-6.

SECTION 3 OPERATION & MAINTENANCE
Once the toothsetter alignments have been checked and adjustments have been made,
you are ready to measure and set blades.
Sharpening removes metal from the face of the tooth. This eventually reduces the set to a
point where the blade will not cut very well. Set should not vary more than (±)0.001 from
one tooth to the next.
The following steps will take you through operation of the toothsetter.
Note: Refer to the Tru•Sharp™ Blade Handbook for recommended set specifications for
your sawing application.
3.1 Blade Installation
1. Clean the blade and deburr before putting it in the toothsetter. Otherwise, sap
buildup on the blade or tooth will give false set readings. Metal burrs created by sharpen-
ing also will cause false readings.
2. Mount the blade in the toothsetter. Place blade between the clamping plates and on
the three guide assemblies.
NOTE: You will need to move both the left and right index pawl assemblies down and out
of the way. These will be adjusted later.
3. Set the clamping assembly to hold the blade. The clamp is set at the factory to lock
the blade firmly as the handle throws over. If the handle is difficult to push forward or
throws over before locking the blade, adjust the clamp nut.
