Work Length Centres

With Exact Spacing, if the last centre will not fit, an extra batten is added to the end (double battens) and the last centre is reduced.
This ensures centres do not exceed the entered (maximum) centres.
Drag the Centres slider to see the effect of the end spacing and double end battens.

With Equal Spacing, centres are adjusted to fit equally, at nearest to (under) entered centres.

If the first or last batten is set-in from the ends, enter the set-in to adjust the diagram and results. All centres will be adjusted to suit the entered set-in. If the first (bottom, or left side) centre is different to the rest, enter the measurement in First Centre to adjust.

DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks

How should we spell it?
