Get free sawmill and bandsaw mill plans online through websites such as ToolCrib.com and TumbledRose.com. Plans range from detailed drawings, video clips, three-dimensional vectors, diagrams and online reading materials. Many of the plans are not safety tested; building sawmills with information obtained online carries some degree of assumed risk.
As of 2016, some of the topics covered by the tutorials on TumbledRose.com include drive unit concepts, blade installation, mounting and wheels. ToolCrib.com provides links to Google books with plans, diagrams and instructions for developing various sawmills featured in publications throughout the last century. A homemade bandsaw using pipe fittings and auto parts, for example, was featured in a Popular Mechanics issue from 1935.
Trees2Money.com notes that many commercial mills do not accept urban logs because metal objects and/or nails are sometimes embedded in the wood. Owning a sawmill provides the ability to make use of wood from a variety of sources. As of 2016, replacing blades that are damaged as a result of nails or foreign objects is typically around $30, according to the website.
