4-404-41 4-42TREADSOn open stairs, cut the closed side of the tread until the proper angle is achieved against theclosed side skirtboard and trim until the mitered return portion fits snugly to the outsideskirtboard. Some filing may be required to achieve a custom, finished installation. PHOTO 4-40.NOTE: The width of a mitered return tread may need to be adjusted to create a codecompliant overhang (i.e. a 10" run and an 11-1/2" tread would not meet the maximum allowableoverhang of 1-1/4" set by many national codes). To do so, rip the tread on a tablesaw to themitered return joint and complete the cut with a handsaw or jigsaw. PHOTO 4-41. If thisleaves the portion of the return that wraps around the skirtboard too long, cut to length andreshape with sanders or a router equipped with a 1/2" radius roundover bit. PHOTO 4-42.CONSTRUCTION ADHESIVEWhen all the treads are pre-fit, begin final installation byinstalling the first tread or starting step/starting newelcombination. The use of construction adhesive is stronglyrecommended on all wood-to-wood connections. PHOTO 4-43.NOTE: Check Over-the-Post starting newels with a level andshim the starting step as needed. PHOTO 4-44.Treads for closed stairways can be cut in the same manner asclosed risers (See Chapter 4, Page 11).4-434-4414 CHAPTER 4 - STAIR BODYC O F F M A N S T A I R P A R T S • S I N C E 1 8 7 4
