We regularly re-machine slabs brought to us by people that have purchased timber elsewhere that is not properly dry and it has bowed or buckled. If we didn’t do this our lovingly kiln dried timber will be back up to 16-18% by the end of winter.
This is why our timber stored in Donnybrook is stored in a heated/insulated shed after it has been dried.
The exception to this is thin boards used at the end of summer. The atmosphere simply does not get dry enough for long enough periods of time to get the moisture content down to an acceptable level. Timber dried in Pemberton or Cowaramup (for example) will never dry out to a satisfactory moisture level for indoor furniture. Timber that has been air dried in the wheatbelt for a suitable time period will be nicely dry because the atmospheric conditions in that area are very dry. It is for this reason that we gently air dry our timber first until less than 20% and then finish it in a kiln.Īir dried timber may never get dry enough for use with inside timber projects - it depends on where it has been dried and for how long. Ever been climbing around in there in summer? It’s HOT. Imagine the effect of putting green sawn timber into a roof space on a new home with a tin roof. It is for this reason that much recycled building timber is stressed greatly. If you take green sawn timber and bung it into a kiln and heat it to anything over 50 degrees or even less sometimes, yes it is going to be stressed (it’s a bit more complicated than that, but that is the crux of it).
