great idea, how do you get them to secure at various intervals? have you used a slide bolt locking mechanism and are the edges of the timber sections set into a channel for ease of sliding.
would like to see a small video on there construction in the future if able.
From the photo it does seem that slide bolts have been used, and there are holes for the bolts at regular intervals rather than a channel. If you'd like to build something similar I suggest you start a new discussion with some photos and plans - I'm sure our helpful community members would be happy to assist. Starting a new discussion would ensure your post is a little more visible - this gallery post is over a year old so is a little hidden.
Let me also extend a very warm welcome to Workshop. It's terrific to have you join us. Please feel free to post anytime you need a hand.
