So this is where I am up to as it stands :)
Here is a 2ft destroyed section. This one is actually fully joined (can’t be separated).
From another angle
This one overlaps nicely and can be separated for a 2ft spacer to be installed.
Here is an example of how the spacer will sit. As you can see I need to finish 2x Spacers and 2x end points to complete the wall.
Also Kaelo is coming to help me tomorrow on my Siege Wall gate :) so come back tomorrow and have a look at the design I cadded up (as well as hopefully another big update).
