Scribe Fit Construction
Our system is based on overscribe techniques. The most common notch we use is called a compression fit saddle notch. Careful techniques are employed to give the inside of the notches a shallow concave shape and to keep the leading edges flat. Scarfes are planed flat to close the grain and wax is applied internally to slow down drying.
Lateral grooves are true Swedish copes and receive special attention during cutting to ensure proper angles and depths are maintained, allowing for the proper application of internal sealant.
They are then hand gouged to make a smooth concaved groove while closing the grain of the wood. Wax is also applied here to slow down internal drying.
Logs are insulated with 2 bands of Emseal and sheep's wool. The top of the logs are kerfed and wedged to localize checking. Using the combination of notching, shallow cove, lateral grooves and kerfing techniques has proven to be very effective in controlling checking while minimizing settling and shrinkage, at the same time eliminating slump.
We have been using this particular system with great success since 1984, however, it is based on Scandinavian technology that is hundreds of years old.
