Today we're looking at an epic circular tower technique by Poul-Erik Borre
on Flickr. It does use a lot of parts, but the technique can be adapted to smaller scales, it just won't look quite as good as it does in his 'Water Tower' MOC: https://www.flickr.com/photos/dk_titan/42992802720/in/dateposted/
The construction relies on a few key parts; for the outer cylinder 1x1 headlight bricks are placed on their sides along with 1x1 studs (although these could be 1x1 cylinders to save parts). The 1x2 tiles are then attached to the headlight bricks, creating the masonry pattern. The cylinder is created by using a internal structure of plates that are angled by turntables, allowing it to be reinforced and stay strong no matter how large the scale is.
