Corrected Router, Looked like a 2200 to me but I stand corrected.

I seen this jig while cruising a festool site. Thought man its kind of pricey for what it is. But after seeing this video of it being used. Im gonna get me one .

You can also do essentially the same thing for cheaper using two fences.

I tried out one of these back in the day when you could call Festool USA and they would send you what you wanted to try out at no cost. I never tried to get any tools sent, but did try out some of the more esoteric accessories like this one. I can tell it does what it is supposed to do well, but I do think with the right motivation a similar quality jig could be made for significantly less cost. I needed it for some full mortise lock sets, but ended up going with dedicated lock mortise set. I have the Templaco (https://www.templaco.com/). In my case I had some unique locks and they were able to make me custom templates for their system at very reasonable prices. Their base set makes doing standard lock installation almost too easy.
