Number line with hopping figures

Also: sandpaper (grit 120 and 240), a utility knife or fine saw and, for joints, a rubber mallet.
Carving and finishing
- Clamp the workpiece flat on the spoilboard or secure it with double-sided tape, and set the origin as shown in the carving assistant.
- Engrave numbers and ticks, mill the slots, then cut out strip and figures.
- Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
- Before gluing, dry-fit everything. If a joint is too tight, increase the clearance by 0.05 mm and carve the part again; if it wobbles, reduce it.
Assembly and final touches
- Paint the figures and add the eyes. The figure stands with its tenon in a slot and hops from number to number for each sum.
- Sum 7 + 5: figure on the 7, hop five times to the right; going past 10 shows the step across ten.
