Loading 1. Small end about 1ft. from end headblock.

2. Orientate bowed logs so that bow is at 45° concave

upwards away from the headblocks. Sawing

A. 6-10in. S.e.d.

1. 1st cut. Use the linebar and shadowline to make a first cut

2in. from and parallel to the pith.

Set the line bar to % marked s.e.d. less 2in. plus

small end bark thickness. For example, for a 9in. log,

4^-2 plus bark thickness of ^in. gives 3in.

Set the small end headblock and, if the log has taper, move the line bar back an inch or so and move the butt end

across until the shadowline appears parallel to the centre line of the log.

2. 2nd cut. Turn the log 90° and using the shadowline position

the log so that the second cut will be parallel to the log centreline and give a small end arris with no more than a ^in. width strip of wane.

3. 3rd cut. Turn the log a further 90°. The headrig assistant

will set the hackstand gauges to 4 3/16in. (+ l/16in. tolerance). After the cut bring the carriage back past the saw so that the headrig assistant can check that the cant measures 4 3/16in. (+ l/16in.) at the butt end of the log.

4. Discharge the cant. B. ll-14in s.e.d.

1. Procedure is similar to that for 6-10in s.e.d. logs.

2. Linebar settings are \ marked s.e.d. less 4%in. plus bark thickness.

3. Backstand gauge setting for the 3rd cut is 8^in. ( + l/16in.).

4. If a ll-14in. class is so badly formed that a 8%in. cant cannot be cut, use the 6-10in. class cutting pattern.

5. Cants will be resawn by the breastbench. C. 15in. plus s.e.d.

1. Procedure as before except that linebar settings are ^ marked

s.e.d. less 6%in. plus bark thickness and hackstand gauge

Tolerance + l/16in. all sizes.

Advise the headrig assistant of the actual size (signal H O.K.) 2. Check that the sawyer is not exceeding the wane allowances

(max. width of strip of wane is ^in.) on logs of normal form. Wane allowances may be exceeded with bowed or kinked logs. 3. Assist the breastbench sawyer by turning all slabs so that

their sawn surface is facing downwards and all cants so that the unsawn face points towards the breastbench sawyer.

4. Using a white aerosol paint spray for bark surfaces and a black lumber crayon for sawn surfaces, mark the uppermost surface of each slab and cant so that tree and log

identification is clearly legible to the breastbench sawyer,

tailer out and marker. The identification will be the

same as for the log, for example 012/1, with further

identification of the part of the log, for example 012/1/1, 012/1/2, 012/1/3 for the first, second and third slabs and

012/1/4 for the cant. The order of parts will be recorded

on a blackboard visible to the breastbench crew and the marker.

5. .An operation time sheet will be filled in. The time from

load to load (loading a log on the carriage) will be recorded and within that period delays due to abnormalities

(adjustments, downtime) will be recorded. 4 3/16in.
