The key factors are less about “hardwood vs. softwood” and more about:1.Log diameter — the mill has a maximum throat/capacity;2.Blade type — hardwood usually needs the right tooth profile and sharp blades;3.Engine power — dense hardwood takes more horsepower;4.Blade sharpness — dull blades struggle badly in hardwood;5.Log condition — dirty bark, embedded metal, or very dry logs make cutting harder;6.Hardwood is tougher on blades.YSDMILL sawmills are designed to cut hardwood logs, including large-diameter hardwood.
For a band sawmill, the most common blade size is usually:1¼ inch (1.25") wide × .042" thickwith blade lengths depending on the mill model—often around 125" to 173" long on portable mills.
The main limits are:Throat width / max diameterBed lengthEngine horsepowerBlade width and strengthLog weight (sometimes weight is the real limit before diameter)Quick rule of thumbFor most common portable band sawmills:Expect roughly 24–36 inch diameter logs and 12–16 foot lengthsThat covers the maj
