Very nice video and a good review also ,I don't speak French but I got every word
I have been using Marc's S. way for about 8 years now and I have been pushing his way for about the same time..
May I offer a tip or two..use wider stock and then rip it to size after you the bits on the stock..
Next tip make a sub fence for your Incra fence out of 3/4" MDF in that way you will have a zero Clearance setup,all that you need to do is push the in feed side of the fence into the bit
and the out feed also (but you don't need to do the outfeed sdie the norm) once you have the bit set, this will give you a chip breaker right on the fence and no rip out on the stock at all..and it's quick way to set the bit height also.
To make the zero clearance parts fire up the router and just side the sub fence into the bit and stop at the bearing..
You can use the sub fence for all the Sommerfeld bits just flip it over and use the clean end for the new setup..
Doing it this way you don't need to adjust the fence because most of the bearings are the same size..but not all, just a time saver tip..
But using wider stock is a real time saver and if you damage one just rip off one more part and put the pattern cut on it...
