Wax foundation has some advantages over letting bees build their own comb
* it provides a guide for bees to build straight comb. Without foundation, the beekeeper runs the rish of having comb built outside the hive frame when they strat, preventing its easy removal for inspection.
* foundation built comb is ususlly stronger in part due to the wiring embedded in the wax. This allows for centrifuge extraction.
* foundation allows beekeepers to increase the size of the cells on the honeycomb. By stamping bigger cells on the foundation than what bees would naturally build, the beekeeper is guiding bees to build bigger cells, increasing the size of worker bees as well as the volume of the cells for honey storage.
Wax foundations are made in various sizes, depending on the frame they will be inserted into. If needed, roller knife is used to cut wax foundations.
