Producing beautiful trunk slices is a significant development step in wild wood processing, as sawing off a trunk slice requires some practice in handling the saw. For the grinding of trunk slices from a diameter more than 10 cm, the use of a 220-volt drilling machine is advisable. The accessories available for the drilling machine makes the grinding of larger trunk slices a relatively simple matter. This is especially appreciated by those who once grinded a trunk slice by hand. How to handle the drilling machine for grinding the trunk slices is explained in detail in the workshop.
