I finished this a few days ago. I built it for my daughter to rock my new grand daughter. I had never built a rocker before but she wanted one. I used pine only because I have a lot of it! I didn’t think pine would be strong enough so I ripped it into 3/16” strips then glued and clamped them in forms I made for each piece. The pine is so much stronger laminated than it was before, heavier too. To hollow out the seat I ran it diagonally across the blade in my table saw then fine tuned it with an angle grinder and a flap type sanding disc. I used dowels interlocking joints where I could. It’s way stronger and more rigid than I expected. I gave it to her on Easter.
