OK, I am going to start parallel to both "rails" changing direction at the appropriate angle to follow the rails. The strips will maintain direction through each 90 degree turn. Like this http://www.flickr.com/photos/83726742@N ... hotostream
I'm going top put in Bruce pre-finished Fulton strip square edge 3/4" natural Red Oak.
The staircase is brand new with new 3/4" landing tread which continues across the top of the stairs, railing, and balusters. However the floor side of the landing tread is square edge, no TorG. Oops. The balusters are too close to the edge to run the router down in place. However, at least I should be able to put a groove in the tread at the top of the stairs for the new floor behind. I'm thinking the rest of the landing joint to the strips along the railing will not be critical since it doesn't get traffic. Does this sound reasonable? Sub-floor is solid 3/4" plywood.
There's nothing special in the Bruce install instructions regarding the square edge. Is there anything special to watch out for with the pre-finished square edge to make this job come out good?
