Step 17Prepare End-stop for Moving Rail
iImage Information

Mark the ends of the dowel pins with a Sharpie or a dab of paint. Close the moving rail against the moulding on the left-hand end panel. The dowel pins should leave marks where they hit the moulding. Drill 5/16" holes into the moulding at those points, deep enough for the dowel pins to fit all the way in (at least 1/2"). The moving rail should now close the crib completely, and the dowel pins should slide in and out without resistance. If the pins are tight, open up the holes with a 3/8" bit.
The upper corner of the moving rail isn't stable. You should choose to position the dowel pin centered
on the end-panel moulding as shown in the picture.
