Precision of the sawmill components
The sawmill is constructed of extruded aluminium
proles. This material can, by nature, deviate
somewhat when it comes to angles and atness.
When designing the sawmill, we have taken this
into consideration, so possible deviations will not
affect the functions of the sawmill.
One place where the slightest deviation is clearly
noticeable, is the joint where the ends of the
guide rail sections meet. It has been shown that it
is very difcult to make such a wide crosscut at a
precise angle. A saw blade is quite simply not more
precise then +/- a couple of tenths of a degree, and
this results in visible deviations. These deviations,
however, are of no importance, provided that you
do not press the gap closed. Press the guide rail
sections together without using force. The joint
coupler will adjust and secure the guide rail sections
in relation to each other.
For the sawmill, we want to have as exact t as
possible of the plastic glides of the log lifters. Plastic
is soft and difcult to process. This can result in the
log lifters being somewhat difcult to move. If this
is the case, use ne sandpaper and polish the plastic
until the log lifters run easily. Usually, the plastic will
have worn down after a couple of days use. (Before
polishing, read the section on adjusting the log log
lifters on page 39).
Demands for precision
We are convinced that a chain sawmill can provide
as good results as, or better results than, other
small-scale sawing methods. A large number of our
customers have reported that they have never had
better wood products than those they have sawn
themselves. However, it is natural that we also meet
customers who want to improve on the precision.
Experience has shown us that variations in sawing
results can have many explanations. The choice
of raw material is vital. Cutting good boards from
short, large-diameter logs is considerably easier
than getting high precision results from long, thin
ones. Tensions caused by storage or place of growth
can cause problems. Some tree types cause more
problems than others, etc.
The precision requirements also vary. A result that
is satisfactory for someone sawing boards for rustic
fence posts may not be good enough for someone
sawing boards to be used in construction without
being planed rst.
If you have gone through the various steps
for adjusting the sawmill, checked the cutting
equipment and observed the effects of tensions in
the wood, but still do not get the sawing results you
expect, please contact us at Logosol.
