I was contracted to do a job that involved the installation of 30 - 4' X 12' sheets of fiberglass skined plywood. The sheets were very badly warped. The job would have been almost impossible to do without the Festool TS 55 & guide rails. This was the first large job that I used the Festool saw & rails on. I could not believe the amount of time that was saved by not having mark full length lines & free hand cutting the sheets with a power saw. And to top it off, every cut was as good as the factory edge. Chris R., Indiana
