The summary is:
The speaker demonstrates how to make a simple jig that attaches to a chainsaw and allows it to cut flat boards from logs. He explains the materials, dimensions, and assembly of the jig, and shows how it works on different sizes of logs. He also compares it to other methods of milling, such as using a circular saw or a bandsaw. He discusses the advantages and disadvantages of using a small chainsaw, and gives some tips on how to get better results. He shows the boards he produced and how he plans to cure and plane them. He concludes by saying that this is a low-commitment and inexpensive way of milling wood, but it may not be worth it for everyone.
Here are the key facts extracted from the text:
1. The text is a transcript of a video about how to make a chainsaw mill jig and use it to cut lumber from logs.
2. The chainsaw mill jig is made of 2x4 blocks, plywood, drywall screws, quarter-twenty bolts, wooden washers, and a coupler nut.
3. The jig attaches to the side of the chainsaw bar and rotates on a 2x4 rail that is clamped or screwed to the log.
4. The jig allows the chainsaw to cut a flat spot on the log and produce boards of various thicknesses.
5. The author uses a small and lightweight chainsaw (MS 170) with a thin kerf and a 30 degree angle chain.
6. The author faces some challenges such as deflection, chain problems, rain, and imperfect cuts.
7. The author compares the jig method with other methods such as using a circular saw, a sawzall, or a bandsaw.
8. The author produces seven boards from two maple logs that are about 7 and 14 feet long and 10.5 and 15 inches in diameter respectively.
9. The author paints or applies polyurethane on the ends of the boards to prevent moisture loss and plans to air dry them for a year before planing them.
