I finally completed the Crib, have it assembled and it is in use.
I got a couple questions about the mounting hard ware. The side pannels are removeable. They are supported by Mortise and tennon joints and a screw from the side pannel will lock into a threaded insert along the corner posts. I wanted to conceal as much hardware as I could, and the open part on the side pannels will be capped.
The matress frame attaches directly to the corner posts to threaded inserts at four different levels as he grows.
The finished project. Feel free to let me know of any feedback or areas of improvement.
I’ll get some teething rails on it soon before he chews his way out of it.
