I recently had to trim out the windows of my new shop. Never thought I would prefer a circular saw to a miter saw for installing casement trim - not that I install trim much anyway being a hobbyist - but that was the case when trimming the windows in my shop recently. I do have a miter saw, a cheapie Delta Shopmaster that is accurate enough. But my miter saw setup is limited to the saw only - no extension tables with hard stops, dust collection, etc. Since there were four windows to do and the side casings would be of equal length (and a length short enough to allow me to use my flag stop on my MFT fence), I used the TS55 with the MFT 3.
I apologize for some of the photos. No lighting in shop at the time.
Setup:


Flag Stop:

After installing the side casings, marking the head casings was just a matter of resting the trim upside down on the side casings and marking.

The zero clearance strip made aligning these marks a piece of cake.

Finished window:


I had my nephew, Matt fill all the nail holes (lucky him!). He's a sophomore (H.S.) and is taking his first woodworking class in school. He also got to use the nail gun and make most of the cuts with the TS 55. He commented on how easy it was to use the saw (and what a blast it was using the nail gun!)

In this case, Festool definitely changed my normal course of work (for the better). Accurate, repeatable cuts with virtually no dust! And as a testament to the ease of use and safety of their tools, Matt made the majority of cuts with no effort.
