Boy this thread has been going on for some time now, and with a lot of very useful ideas. All this time I have been trying to see what's best for my needs in my shop by following this thread. I do like to have reasonable, read eyeball, precision in cut angles and lengths, and as long as all four sides of a box are same length and perpendicular to each other, I'm happy.
All of this is to say, I spent a lot of time and money - mostly on Woodpecker stuff - to achieve the desire goal. Last week I removed all the Festool protractors, fences, guide stops from my MFT/3s, and found Qwas dogs and a good tape measure like a Tajima or a FastCap were all I needed to cut square and to length. There is 1 hugh provisio - I needed to start with a straight edge on the sheet goods. After that aligning the straight edge against 2 or 3 Qwas dogs, and backing my fence up to 2 Qwas dogs set perpendicular to the cut edge, I was good to go. The length of the cut is set by the tape. Good, quick, and cheap. Now if only I could find a use for the OTT 26" square!
