SECTION 1 OPERATION
The Shingle/Lap Siding Option (SLR) allows you to quickly saw tapered shingles or siding
with your Wood-Mizer sawmill. Read the instructions in this section completely before
operating the SLR.
See Figure 1-1. The major components of the SLR option are identified below.

1.1 Installation and Setup
1. Position the SLR on the mill bed with the mounting brackets around the front and rear bed
rails. The shift lever should be at the front end of the mill. Make sure the SLR frame is
lying flat on the bed rails. DO NOT tighten the clamp bolts on the bed rails. The clamp
bolts should only be tightened before towing the sawmill with the SLR attached.
2. Slide the SLR frame all the way over toward the inboard side of the sawmill bed until the
SLR stops touch the bed rail stop blocks.
See Figure 1-2.

1.2 Cutting Wood Shingles
To cut tapered shingles, up to six wood blocks are clamped over each cam. The siding tilt
adjustment bolts are adjusted down to prevent the lifting rollers from tilting the SLR frame.
When the shift lever is thrown, the cams lift the back of each wood block. The shingle
taper adjustment bolt is used to control how much taper is sawn into the shingles.
1. Saw a log into a cant the width you want your shingles. The maximum width the SLR can
accept for shingles is 12” (304.8 mm). Use a chainsaw to cut the cant into blocks the
length you want your shingles. The minimum length the SLR can accept for shingles is
14” (350 mm). The maximum length for shingles is 24” (610 mm). To reduce the risk of
vibration causing the blocks to work loose from the clamps, a maximum block height of
12” (300 mm) is recommended.
2. Install the SLR to the sawmill bed (See Section 1.1).
3. Adjust the shingle taper adjustment bolt all the way out and throw the shift lever up.
4. Adjust the siding taper adjustment bolts clockwise until you can spin the siding lift rollers
by hand. The lift rollers should not tilt the SLR frame when the shift lever is thrown.
5. Adjust the clamps as close to the SLR frame as possible. This will insure the rear of the
blocks are positioned over the cams. Turn the clamp handles counterclockwise until each
clamp is all the way out.
See Figure 1-3.

6. Position the first block in the front clamp assembly with the front edge of the block even
with the front edge of the clamp.
7. Slide the outer clamp half in until it contacts the block. Turn the clamp handle clockwise to
firmly clamp the block in position. Be sure the block is securely clamped so the block will
not come loose while being cut.
8. Repeat procedure to clamp remaining wood blocks.

9. Before adjusting the SLR for the amount of shingle taper, push the shift lever down and
make a trim cut to level all of the blocks.
10. Move the blade to the top of the back edge of the first block. Raise the shift lever until the
block tilts to the desired taper. For example: if you want to cut shingles that are 1/8” on
one end and 5/16” on the other end, adjust the SLR for 3/16” taper (5/16”-1/8”=3/16”).
Adjust the shingle taper adjustment bolt until in contacts the shift lever linkage. Secure the
bolt in position with the jam nut.
11. Always follow all safety and operating procedures explained in the sawmill operator’s
manual when using the SLR.
12. Raise the shift leverand lowerthe blade the thickness of the thin end of the shingle. Make
a cut and return the carriage. Each shingle should match tapers to the setting you want. If
they don't, repeat Step 9 above.
13. Push the shift lever down and lower the blade the thickness of the thick end of the
shingle. Make a cut and return the carriage.
14. Repeat Steps 12 - 13 down to the heart of the cants. Unclamp the cants, flip 180° and rec-
lamp. Continue sawing down as low as the SLR clamps will allow.

1.3 Cutting Lap Siding
To cut tapered siding, a single cant is clamped in the SLR. The siding taper adjustment
bolts are adjusted up so the lifting rollers tilt the SLR frame. When the shift lever is
thrown, the SLR frame tilts sideways.
1. Saw a log into a cant the width you want your siding. The maximum width the SLR can
accept is 12” (304.8 mm). If necessary, use a chain saw to cut the cant to the length of
siding you want.
2. Install the SLR to the sawmill bed (See Section 1.1).
3. Adjust the shingle taper adjustment bolt to 1/4”. This will stop the shift lever when the lift
rollers reach their maximum height. Adjust the siding taper adjustment bolts all the way up
so they do not lift the SLR frame from the bed rails.
4. Adjust the clamps so the inner halves are inside the cams (used for shingles only). This
will insure the cams don’t contact the cant. Turn the clamp handle clockwise until the
clamp is inside the cams.
NOTE: To saw cants wider than 10”, the cams must be
adjusted out of the way. Be sure to mark each cam location

gles. If the adjustable clamps do not provide enough adjust-
ment to secure the cant, use wood spacers between the
cant and clamp.

5. Position the cant so it is centered in the SLR frame.
6. Tighten the front clamp to secure one end of the cant. Slide the outer clamp half in until it
contacts the block. Turn the clamp handle clockwise to firmly clamp the block in position.
Be sure the block is securely clamped so the block will not come loose while being cut.
7. Repeat the procedure to clamp the rear of the cant.

See Figure 1-8. Determine the dimensions of the siding you want to cut.
See Table 1-1. The amount of taper is limited by how wide the cant is.
8. Before adjusting the SLR for the amount of siding taper, pull the shift lever up and make a
trim cut to level the cant.
