Calculators

Units:

* Unit selection affects all calculators on this webpage.

All values are interpreted in inches. Enter values as decimals or fractions (e.g., 2.5 or 2 1/2 = 2 1/2"). Do not include units in the input. Feet, yards, and other units are not used. All results are returned in inches.

Wooden Planter Compound Angle Calculator

Enter the front slope, side slope, planter height, and board thickness. If only one slope is entered, both faces use the same slope. If board thickness is left blank, the calculator assumes 3/4 in. or 19 mm. Results give table saw blade tilt, miter gauge setups, edge bevels, and board widths.

Blade Tilt (off 90°): The amount the saw blade is tilted away from 90° for the compound end cuts. -
Blade Setting (90 - Tilt): The blade angle as read directly on the saw, equal to 90° minus the blade tilt. -
Miter Gauge Setup / Front: The miter gauge setting used when cutting the ends of the front boards. -
Miter Gauge Setup / Sides: The miter gauge setting used when cutting the ends of the side boards. -
Front Edge Bevel: The bevel angle cut on the long edges of the front boards so the assembled planter sits flat. -
Side Edge Bevel: The bevel angle cut on the long edges of the side boards so the assembled planter sits flat. -
Front Board Width: The overall width of the front board, measured tip to tip across the beveled long edges. -
Side Board Width: The overall width of the side boards, measured tip to tip across the beveled long edges. -

Segmented Bowl Ring Calculator

Provide any three of the four primary values (wall thickness, stock thickness, wall slope, or ring spacing), and the calculator will solve for the missing value. This allows you to work from known or desired dimensions and determine the remaining geometry of a segmented bowl ring.

These two fields are optional. Enter either bowl height or ring count to calculate the other using the stock thickness. Only one of these fields needs to be filled in.

Wall Thickness: -
Stock Thickness: -
Wall Slope: -
Ring Spacing: -
Bowl Height: -
Ring Count: -
