Hi Blister:
Regarding the SomeTimeWoodWorker post, I am the guy who developed Router Boss. But, we did not do it alone. There were 3 engineers helping us and we spent more than a year on the project.
Router Boss shares many concepts with WoodRat which we previously imported to the USA, but it is not the same machine and does not share any interchangeable parts with WoodRat. We were issued a patent on our improvements and we expect a second patent to be issued this year. WoodRat has several international patents, but Router Boss does not infringe on any of them.
As James indicates, Router Boss includes several digital options for positioning of cuts. We also sold a digital option for WoodRat, but it sometimes got in the way and had to be removed. With Router Boss we were able to design the digitals so they never have to be removed. Plus, as James says, Router Boss includes LED lighting and a laser projected crosshair marking the center of cut. Also important, Router Boss provides built-in dust collection ports both behind and in front of the bit.
Note that the digital is an option. It is helpful, but not necessary. Unlike WoodRat, we also provide 24" or 600mm of rules that can be used with a cursor to positions cuts. We also provide the ability to print dovetail layouts on your computer then stick them on the rules.
We undertook development of Router Boss to provide a more robust and versatile machine for the user community. An excellent independent review of Router Boss is available on the benchmark.20m site
