Ron and Ryan, thanks for making this available. I do have 2 questions:
1. I see you note the MFT holes as being 20.2mm, mine caliper out smaller and (as I believe you know) I made the rip dogs 19.9mm which fit great in my MFT. I believe they fit your MFT also, so can you help me understand the discrepancy? Has Festool changes the size of the holes for new MFT's?
2. What software do you use for the drawings? I am in the market for a CAD program but some of the prices are staggering. I don't have a lot of experience with CAD and am looking for something capable of doing fairly simple stuff like dogs, etc.
Would appreciate any feedback you can provide.

I just called for 20.2mm because that was mine averaged. Some slightly smaller & some slightly larger. That geometry will be what your CNC guy can use to generate the toolpaths for your top -- simply tell him what size you would like yours to be and he can adjust accordingly. For your rip dogs you will want (ideally) the holes to have ~.005" clearance. The rip dogs are slightly on the loose side in my MFT/3 but certainly acceptable.
Steve Adams (QWAS) may have an actual "target" hole size that Festool shoots for on the MFT's.
The software I used is very expensive and not practical for a casual user -- I hear lots of good about Google's SketchUp software and the price is right.
