When a questionable tree threatened his house, [John Heisz] did the sensible thing and called in a professional to bring it down. But with a flair for homebrew tools, [John] followed up with a seemingly non-sensible act and built a quick and dirty DIY bandsaw mill to turn the resulting pile of maple logs into usable lumber.

A proper bandsaw mill is an expensive tool. Prices start in the mid-four figures for a stripped down version and can easily head into the multiple tens of thousands for the serious mills. [John] makes it clear that his mill is purpose-built to deal with his leftover logs, and so he made no attempt at essentials like a way to index the blade vertically. His intention was to shim the logs up an inch after each cut, or trim the legs to move the blade down. He also acknowledges that the 2-HP electric motor is too anemic for the hard maple logs – you can clearly see the blade bogging down in the video below. But the important point here is that [John] was able to hack a quick tool together to deal with an issue, and in the process he learned a lot about the limitations of his design and his choice of materials. That’s not to say that wood is never the right choice for tooling – get a load of all the shop-built tools and jigs in his build videos. A wooden vise? We’d like to see the build log on that.

We’ve featured a surprising number of wooden bandsaws before, from benchtop to full size. We’re pretty sure this is the first one purpose built to mill logs that we’ve featured, although there is this chainsaw mill that looks pretty handy too.
