Several have mentioned variations on this theme. I recently bought the TS55, MTF, Rotex 150, and CT22 to remodel/update the house we just moved out of. The Rotex did great knocking down some over-ambitious ceiling texture, and knocking the grain down on the deck I just pressure washed (another new tool). I used the TS55 to install a beautiful laminate cork floor in the kitchen.
We had the kitchen cabinets resurfaced, and new doors installed by an outside contractor. I then fabricated a particle board counter, laminate top, and oak trim. Perhaps not the latest style, but it still looks good to me.
I bought a cast acrylic sink from Lowe's. Instructions said to invert on surface, trace outline, cut opening 1/2" inside the line. Luckily I looked VERY closely before proceeding. The damned sink was not square; it is a parallelogram! I could have returned it (along with the damaged shower door; the vanity counter with the cracked sink; the second vanity counter with the faulty (noticeably uneven) backsplash; the vanity faucet set with incorrect drain parts packed in the sealed box), but it wasn't too noticeable, and I needed to get something done!
So I inverted the counter top section, inverted the sink, traced, and moved in 1-1/2". There was plenty of room to move in closer, and this gave me much greater latitude in case of error. As you all know, it is much easier to cut more material off later if need be, than to put it back when you remove too much!
I then set the counter section on the cabinet to make the plunge cuts with the TS55, and of course, you all know what happened next. The lateral cuts were fine, but the side cuts overlapped the cabinet, and left a kerf mark in the face of the new material. Luckily, (#1) I had the saw sat at moderate depth, and the kerf is only about 1/2" deep. Luckily (#2) the cabinets were done in white laminate, and a quick dab of white silicone caulk camouflaged the ding. I'll show it to my wife after we have a signed purchase agreement in hand.
(When I made this cut, the counter was set over the door underneath the sink. Jeeez - if I had set the blade at max depth, as is recommended to coincide with the plunge limit marks on the saw guide, I might have cut all the way down to the door opening! Unfortunately, even the best tools don't prevent these stupid mistakes . . . )
I can take pride, however, in knowing that the kerf is exactly perpendicular to the top of the counter! A high-quality screw-up is better than a sloppy screw-up, isn't it? (Please say yes . . . )
