SECTION 1 OVERVIEW
1.1 Toothsetter Introduction
There are four steps to maintaining blades used on the Wood-Mizer sawmill. They should
ALWAYS be followed in this order:
1. Blade Cleaning
2. Sharpening
3. Deburring
4. Toothsetting
See Figure 1-1. The blades supplied by Wood-Mizer 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 cut-
ting. 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 BMT100-2/BMT100-3 Toothsetter 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.

1-2 BMT10013doc082115 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
2.1 Toothsetter Mount
Install the crank handle to the toothsetter crank assembly using the supplied hex head
bolt. Be sure the handle is oriented in the "up" position as shown. Install the crank handle
knob to the crank handle using the provided socket head bolt and two hex nuts.
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), hex nuts. 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.

2.2 Blade Support Installation
Attach the three blade support arms to the threaded mounting bar at the rear of the tooth-
setter. Five sets of support arm mounting holes are provided. Use one of the set of holes
for the appropriate blades (BMT100-2: from 1" to 2" wide blades; BMT100-3: from 1" to 3"
wide blades).
See Figure 2-3.
