Lay out equal divider bays
Find clear bay widths and every divider face from one reference wall, including the thickness occupied by each partition.
Measure once. Plan the whole job.
Turn your measurements into layout marks, material quantities and a clear preparation record. Every tool includes a worked example and explains where its result applies.
Workshop calculators
Plan repeated cuts, mark a layout and check an assembly before making.
Count equal cuts from one strip
Reserve both end trims and the saw kerf before counting equal-length blanks from a fixed strip.
Size four rails for a mitered frame
Convert the intended inside opening and rail face width into short-point and long-point dimensions for four 45-degree corners.
Mark an evenly spaced row of holes
Place the first and last hole at equal end margins and calculate all intermediate centres from a single reference end.
Compare a box with its target diagonals
Calculate the diagonal of an intended rectangle and compare two measurements without inventing a pass tolerance.
Convert rectangular stock to board feet
Convert measured millimetre dimensions and quantity into board feet, litres and cubic metres.
Estimate banding for selected panel edges
Count separate banding strips and add a trimming allowance to both ends of each selected edge.
Correct a printed template scale
Use a measured calibration bar to calculate the next print percentage, then verify with a second print.
Prepare a small box for glue-up
Rehearse the sequence and record what is ready before opening the glue.
