Raising tip: lifting a post straight up

Raising tip: lifting a post straight up

  |   Newsletter, Techniques, Uncategorized

From Daizen News, June 2013

During a raising, lifting the post straight up from the top will help place it accurately and safely. We calculate the weight of the member and place a proper screw that we can hook into the dead-volume center, so the lift is controlled.

The hook used to do this is called a transport ankor, and it’s sold by Würth. We countersink and inset the screws, so that we don’t need to climb up the top of the post after it’s set to take the screw out.

Because we pre-stain our timbers, no damage is allowed. The anchors eliminate the strap that would otherwise go around the member. Also, we protect the corners of the post bottom by enclosing it in a box before the post is lifted. This is a money saving preparation  that we strongly recommend.

We include a gasket around the bottom of each post as part of the building envelope.

A nylon-based plate makes a thermal barrier as well as preventing moisture transfer to the post’s end grain. Then our famous Japanese epoxy anchor system goes in to secure the post to the foundation.

Residential Glulam

  |   Materials, Newsletter

From Daizen News, May 2013

Glulam, or glue-laminate, is engineered wood that is twice the strength of #1 grade timber and is sometimes used as a beam.  It is composed of several layers of dimensioned timber bonded together with durable, moisture-resistant structural adhesives.

Glulam is frequently used in large scale projects like airports and manufacturing facilities in order to achieve a large open span. As an industrial component, it looks good, but for a residential application, we use Glulam in a different way.

First, to soften the laminated look, it’s best if the glue in the lamination is clear. Then, we wire-brush the surface in order to blend the glue lines in. Finally, we use a dark stain color.

Glulam can be an affordable alternative to big timbers. At any size bigger than 8 in. x 14 ft., or longer than 24 ft., the cost of kiln dried timber rises to exceed that of engineered wood . . . and then the point is reached where natural timber at that size does not exist. For this project, an industrial feel is part of the design concept, so Glulam is the material of choice.

Charred board finish

  |   Newsletter

From Daizen News, May 2013

A board burned ½-in. deep becomes naturally weather and insect resistant. Charring boards in this way was a common finish in the old days in Japan.

These days it’s more for an authentic look, but it’s functional, too.

Feature: fully enclosed in SIPs

  |   Newsletter

From Daizen News,  May 2013

This project was designed by John Peter Sauter, a Calgary architect, for his sister. It is built on the lake property where they have spent summers since childhood.

The full timber frame structure was completely enclosed in structural insulated panels (SIPs), so that the interior walls and roof are SIPs. (The SIPs have drywall on their inner side.)

Notice that the posts and beams are fully exposed on the inside walls. The unusual timber color is stunning, and the very-well-chosen colors of the walls, ceiling, and beautiful furniture enhance our timber frame ten times over!

From Daizen News, April 2013

We are pleased to announce that we have moved into a larger shop in a better location.

We are now about 20km east of Kamloops, near the Lafarge concrete

plant. The shop is big enough so that we can now fabricate two

projects at the same time.

Our new address:

Thanks for stopping by

  |   Community, Newsletter

From Daizen News,  April 2013

We would like to thank the people who stopped at our booth at the March BC Log Home, Timber Frame, and Country Living Show held in Abbotsford. Our display this year was to show the limits of how much we can bend timber. We have not yet assigned the use of this very curved display.
