I used my LT15 Wide to resaw a floor beam from the 1889 barn that we dismantled in 2022. I milled it to a 4 inch thick slab. The slab wasnt wide enough for the bench but it was about 11 feet long so I resawed two 5 foot long, 9 inch wide sections from it so I could get an 18 inch bench seat. We planed, sanded and finished with poly then mounted the metal legs.
