Stairs ... a little machining...

Stairs ... a little machining...  So this evening I jigged up a router template (first photo) to cut one of the grooves in the bottom of the stairs, just the big landing step for now.  Both steps are in the pipe clamps.  The other clamps are holding the jig in place, and the bags of lead shot are ensuring that the jig lies down flat on the step.  In the second photo you can see the result after I ran the router through the template (but before I cleaned up).  It took three passes to cut a half inch deep groove, 1.5" wide.  I cut the groove a tad longer than it actually needs to be, so that the rib will fit in nicely without worrying about the radius of the router bit.  After I cleaned out the groove with compressed air, I did a test fit of the rib – perfect fit!
