This was free-form built; I worked at a sawmill, so I had an idea of the basic layout. The steam engine was built almost a year ago for this piece. The hardest bit to build was the carriage for hauling the cants pat the sawblade. I wanted a dremel cutting blade to be my saw blade, but I couldn;t find one and wanted to get the sawmill finished, so I used a metal washer instead. I'll replace it with a proper cutting blade once I get a hold of one.
