So I was able to insert all of my pieces for the arm rest support. I drilled pocket holes and inserted screws with them. I had to cut an extra piece because one of the pieces was too big so I cut it down to size but the issue was I drilled before I cut, resulting in the screws to go right through without holding the board to the piece. But it’s all good now. Next step is the back pieces and the leg I’m making for support under the bench.
