nice instructions
I just can't understand your praise for the induction cooktop; the I-field is not only "crazy" fast but also highly controversial
if you put a pot that is too small on it, the electromagnetic field shoots out about 0.3-0.5 m, wildly in all directions
since we are also made of iron, we get heated too (keyword pregnancy)
therefore, induction, no thanks.
there really is a tool for cutting holes at Ikea, but it is in the office section for drilling cable tunnels in tabletops and is too large for faucets
