Using Screws in Wall Logs
Some people might be surprised to hear that manufacturers don’t go out of their way to produce logs that sometimes could be mistaken for a banana or propeller.
All logs are machined perfectly true, no bends or twists at this stage. However, wood is wood and can decide to take its own revenge on the machining process – varying moisture content along a logs length can result in a perfectly true log bending and twisting.
Any manufacturer that guarantees ALL its components arriving with the end user as straight as when they were created is treading on dodgy ground.
Are twisted boards a problem ?
In just about all cases, a twisted board can still be used without compromising the structure in any way. If you identify the badly affected boards, it is worth using these towards the bottom of the wall so that as the weight increases above it, the board is held in place.
All Eurovudas cabins come with a pack of long screws to assist in holding twisted logs in place – personally, I will avoid using screws at all costs. Why ? – Well, as previously stated, the moisture content of the walls logs will vary throughout the year resulting in the wall height changing.
If you have screwed the logs together, it prevents the logs settling and finding their natural position. Worst case scenario when the logs shrink as they loose moisture will be a gap between the logs due to them being held apart by the screws – if at all possible, do not use the screws – the strength of the wall will not be compromised !
