I am making 16 windows for a 1940's cabin. So far they are doing their job well on my desk with two routers. It's good to have 2 tables because it takes a while to climb and fencing, although it's not just a bitset. Very inexpensive for the cost of this entire process. Cedar wood for a couple of windows costs more than bits. There is a video by Infinity Beats on YouTube showing how to use these beats. Very helpful.
