This is not a monthly cost or a replacement schedule. It shows sourced examples of items that wear out or get used up.
What this estimate does not include
The complete path is scoped to material the 10-inch saw can handle. Larger work needs a larger saw, and freight is especially important for the 250-pound sphere machine. Sales tax, shipping or freight, raw material, replacement timing, and workshop-specific electrical or plumbing changes are not included.
