Your measurement
Your diameter in three steps
A piece of rigid cardboard, a compass and the balls you want to round. That’s all.
Step 1
Draw and cut out
On a piece of rigid cardboard, draw a circle 84 mm in diameter. Cut out the inside of the circle cleanly.
Step 2
Push your balls through
Push your balls through the opening one at a time. The cardboard must not bend or tear.
Step 3
Enlarge if needed
If the balls do not go through, draw a new circle 0.5 mm larger (84.5 mm, 85 mm…) and try again.
Your diameter
The one that lets the most balls just pass through
With a firm push on the ball, without the cardboard giving way. Enter this diameter before adding the tool to your basket: it is made to this measurement.
The right diameter
A tool that does not quite close
The diameter you choose determines the result on your balls.
Slightly too large
To be avoided
The tool closes, but the granules are not ideally packed.
Slightly too small
Well-packed granules
The tool does not fully close around the ball, but the granules are perfectly packed.
The goal
A minimal gap
The tool does not close completely, with as small a gap as possible. This is the diameter to aim for.
