2. Cutting log plywood
You can use small circular saws with just one hand because they are portable and lightweight. Cutting long plywood would be easy with it.
It would be best to use extruded foams or small blocks or used workpieces to raise or support the plywood. This practice will make a deep cut into the plywood possible.
3. Turn logs into firewoods
Table saws or chainsaws are expensive. If you can not afford them, you can use small circular saws to cut long and large firewood into smaller logs.
