Units Radius Joint



Concentric circles For concentric rings, start with outer ring. Adjust for optimal cut size, and hit 'Copy Diagrams' to copy current diagrams to page footer (or print the page). Then enter Inner Radius - Joint Width for new Outer Radius (or drag Radius slider). Adjust number of units to get optimal cut size. 'Copy Diagrams' and continue to create a list of concentric rings. Or hit to automatically enter the new Outer Radius and re-calculate.

Running Outer Gauge run



Enter Outside Radius (not diameter), unit height, width and side joint width and hit Calculate. Drag the Units slider or Hit or to add or subtract units, and find best unit cut dimensions to suit your available paver sizes.

Full Scale Templates Check Full Scale to draw the single unit diagram at full scale to print and cut for a template.

Check inside radius, outside radius, paver width and other dimensions before cutting and using templates to mark and cut the pavers.

Check Circles to draw inner (Green) and outer (Blue) bounding circles to see the bounds of each unit. For a better view of how the bounding circle dimensions fit, keep hitting - Unit to widen units and clearly show the circles.

The running gauge points are square across the outside edge of each unit, and straight across side joints for straight edges and around the outer circle for curved edges.

Check Dimensions Check all dimensions on-site before cutting.


Calculate Diameter and Units per Course using pre-sized units (Fire Pit Blocks etc)

If you already have blocks pre-sized, for fire pits etc, and need to find out how many it takes to make a complete circle, and the outer diameter of the circle, enter single block dimensions below and hit Calculate. The number of blocks and diameter is calculated from the side angles of each block, and assumes no side joints. Add a little to allow for irregularities in block manufacture. This calculation is an estimate, as the block dimensions may not geometrically fit a complete circle. If you add or subtract blocks to alter the diameter, all that happens is the side joints open or close (inner or outer) to adjust for the change. Smaller diameter = less blocks with wider outer joint gaps. Larger diameter = more blocks with larger inner joint gaps.

Input Inches eg: 10.5 or 10 1/2

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
And if you're cutting wet, wear a mask - theres dust in the spray too!

How should we spell it?
