Log Construction Details

A true Handcrafted Notch

 The notch is first scored  1/8" away from the scribe line with a chisel.  Then it is cut with the saw.  After the rough sawing is completed, the notch is finished off by hand with the axe right to the line. A truly " Handcrafted Notch".

Cutting the " V " Groove.

Owner / Builder Dave Wheatley is cutting the "V" groove on top of the wall log. This cut is very dangerous to make, and is why the majority of handcrafter's use the single scribe construction method..  Three passes are made with the saw.  The first pass cuts one side of the " V " and the second cuts the other side.  The third pass makes the kerf cut.  This "V "groove cut is the second part of the double scribe construction method.

Understanding Checking, Shrinking & Settling

Checking: Is the process of cracks forming on the outer surface of the log as the log shrinks. Shrinking: Is the process of water evaporating from the cell fibers of a log. There are millions of these cells in a log which are like tiny straws full of water. As the water evaporates, the straw fibers collapse. So shrinking is the diameter of the log loosing its size. Settling: Settling is the loss of wall height as logs in that wall shrink. This loss in height is accounted for in a building by the use of screw jacks.  Settling will accure in a log wall until the logs reach equilbrium with the surrounding enviroment, usually between 3-5 years.  Our typical wall will have 10 - 12 rounds of logs in it.  We allow 3/4"  of settling for every foot of wall height.  So in a wall, there will be aprox. 5 - 6 inches of settling.

Cutting the Saddle Scarf

Owner / Builder Dave Wheatley hard at work on the show home.  After the saddle scarf's are cut and sanded, the notch is ready for final scribbing.

The " W " Groove Cut.

The " W " has been cut.  On the two legs of the " W " a P-cell gasket is stapled on re-assembly of the log shell.  The notch also gets this gasket as well as fiber glass insulation.  Notice the second log at the top of the photo.  Here is the upside down " W " as the log sits on the wall.  Between the two rows of gasket is fiberglass insulation, which is placed in the " V " groove on the log below.  This double - scribe lateral groove construction provides SIX barriers to out side air & weather.  these are: 1) wood to wood; 2) gasket; 3) insulation; 4) insulation; 5) gasket; 6) wood to wood. The "W "cut is the first part of the double scribe construction method. 

Post & Panel Construction

This piece on piece construction dates back to one of the earliest forms of log construction in the 1700's.  Basically, there are no notched corners, which means that a building using this system requires far less labour to produce than one using notched corners.  One advantage to this system is that there can be long wall length's.  One disadvantage is that there can be an uneven look to the log courses between panel sections.  This construction method is ideal for client's wanting high-end quality, but who are also on a budget.  The panels are scribed together using the Single Scribe construction style.  Post & Panel construction is suitable for any application that you might think of and can be built with both the handcrafted and milled log construction  methods.

Single- Scribe Lateral Groove Detail

Here is a detail drawing showing the Single - Scribe construction method.  This construction is also known as the Scandinavian Full Scribe joinery.  Note there is no cutting work on the lower log.  This is the main difference between single & double scribe construction methods.

Double - Scribe Lateral Groove Detail

In the detail drawing, you can see the upside down "W "and the "V "cut with the kerf cut to the center pith of the log.  The gasket and insulation are installed on the logs at re-assembly of the log shell.  This high end construction provides six barriers against any air or weather infiltration into the home.  No other building system in the log home industry provides this level of quality.

Arch Cutting 2

Cutting the arch end trims on the show home.  The cut is made using the powerful two - man saw.  The saw has a helper handle bolted onto the nose of the bar.

Finishing Package to Dry In Stage.

Here is a basic roof rendering showing the different elements of the dry in package.  The components can be customized as to the owner's needs.

Log Cabin Graph

Here are the most common cabin sizes.  Here you can see how the different cabin sizes compare to each other.  Notice the 4x8 sheet of plywood at the bottom.  A loft can be added as well for more additional living area.

Square Log Wall

Here is an example display of our standard 6 x 8  log corner cut with our band sawmill.  The logs have been milled flat on four sides.  A bit of wain has been left on the edges of the logs for a more rustic, handcrafted look.  The log corner construction shown is known as the butt ' n pass system.  This corner style is the most cost effective to build.  An ideal choice for those on a limited budget.

Machine Lathe Round Logs

     Here is a photo of a small cabin built with the machine lathe round log.  Log diameter sizes are 8 - 10 - 12 inch.  The log diameter effects the bottom line price tag for the log shell construction.  The log corner shown is the saddle notch.  Logs are milled to a uniform diameter.  The lateral groove is the sweedish cope.
