|Timbers that are already kiln dried and milled arrive at Appalachian|
Timber Services. They are then graded and sent on for processing.
|One of the problems with natural wood is it splits as it continues|
to dry over time. To control the the splitting, the stack of blades
pictured above cut slits the length of the railroad timber.
|Timbers then have metal screens tacked over the ends to further|
prevent and control splitting. From here the timbers go into a chemical
bath that pressure treats the timbers to prevent rot and decay.
|Here workers custom shape a timber for a bridge replacement project.|
Saws and knifes are used to mortise the timber to exact specifications.
