1. Stair nosing is 3 1/8" with 3/4" overhang. Will glue and nail with 16g finish nailer. Can you describe
the nailing pattern and spacing? Also, how tight to zigzag Urethane ? I dont want to overkill since the face nailing will be visible here
2. Installing 3 5/8 Kempas (3/4") with 2" Bostitch cleats. Can someone tell me proper spacing of cleats in middle and ends?
I prefer to use star bit trim screws on stairs. Stairs tend to get a karate kick motion when people run up them and I don't want them working loose so I don't use 16g finish nails. See picture below.
I have two drills and make a pilot hole with an 1/8 inch drill. I pattern the holes so I have three screws in each stringer.
It sounds like you are using flooring boards and nosings to make the treads. What I have found works well is to mark the width of the nosing using a scrap piece on the tread sub-floor. Then add the width of the planks and figure out what the rip is going to be and cut the rip piece first. If you install the rip first you can blind nail the planks every 5 to 6 inches and pilot and screw the nosing through the sub-floor and into the stingers.
