Quoted from joelbob:Yeah a deep socket is your friend here. I moved the posts on Stranger Things and had the same battle until I moved the ramp and used a socket. The hole in the wood is tight and you will have to tread them in and out.
Quoted from ForceFlow:A deep socket set. Those will fit over the post and reach the nut at the base.
Any recommendations for a deep socket set? I keep finding my nut drivers sometimes don't do the trick entirely.
