How to Use This Calculator

How the result changes with Wall thickness (in)

Wall thickness (in): Rough-turned wall thickness. Thinner dries faster but cracks more.
Bowl diameter (in): Outer diameter of the rough-turned bowl.
Wood density (0-3): 0=Light (pine), 1=Medium (cherry/walnut), 2=Heavy (oak/maple), 3=Very heavy (ipe/ebony).
Ambient humidity (%): Average relative humidity where the bowl will dry.
End grain sealed? (0/1): 1 if end grain is sealed with Anchorseal or wax (reduces cracking, adds ~20% time).
Drying method (0-2): 0=Air dry, 1=Dehumidifier kiln (~5x faster), 2=Conventional kiln (~10x faster).

Drying time (months): Estimated months to reach target moisture content.
Drying time (weeks): Same estimate in weeks.
Starting MC (%): Estimated starting moisture content based on wood density.
Target MC (%): Target equilibrium moisture content for indoor use.
Crack risk (1-5): Relative cracking risk: 1=very low, 5=very high.
Water loss (lbs): Estimated weight of water that will evaporate during drying.
