A sawmill is a place where logs are cut. Sawmills were greatly improvised with the Industrial Revolution of the 18th century. The first mechanical sawmills were run by water power. But with the introduction of electricity in the 20th century, sawmills are being run by high technology with massive production. The saw mills basically help to transform logs into lumber by going through many processes. Trees are first selected and felled. The branches are then cut and taken to the saw mill as logs. The logs are then differentiated into various species and then sorted by size and end product to be made such as chips, lumber or plywood. The logs are then cut into cants using saws. They are then broken down as resaw or as gang edger. The cut lumber then goes through various processes such as edging, trimming, drying and planning after which the finished lumber, is then transported to the market by shipping.
Types of Sawmills

Saw mills are used for professional work or for hobby purposes. It can be either a part-time business or a full time business.

The process of operating the saw mill requires heavy cost and hence he should be ready to face the expenses before he starts the work.
While choosing the saw mill, he will have to decide which type of saw mill he requires. He can choose between production and kerf. If he requires more production, he should choose the circular sawmill which produces more lumber, while the band saw mills with a thin kerf is able to convert more lumber out of the log. The cost of the circular mills or the band mills and the cost of the saw blades have to be considered. The requirement of the cuts such as horizontal cut or vertical cut or angle cuts will also have to be considered. The capability of the log size as well as the safety measures to be taken, are other features that have to be considered while choosing the right sawmill.
Portable or Stationary Saw Mill
Portable sawmills can be set up in remote areas or at the logged regions, where sawing is done. The cut lumber is then stored and dried. The end products will have to be towed for marketing. If the quantity is large, the towing vehicles should be heavily powered. The setup time for the saw mill and the takedown time, will have to be considered and the costs involved with this process, have to be factored into. The stationary saw mills have a solid foundation. The production continues nonstop in all weather conditions. The log transportation facts have to be considered, as they are not located where the timber is found and will have to be transported through larger distances for being cut. However, they have a huge production rate and they are large in size.
