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. |
