Preparing+the+old+LAS+dome

The old LAS dome from Pex Hill was pre-assembled on my patio so that I could determine what parts would be required to complete it, take dimensions, remove the old rusty hardware and fill and prime the outer suface before being put onto the walls.

The orginal dome had a double metal curved ring. One ring was originally fixed down to the foundation wall. The other was fixed to the underside of the dome. After much head scratching, I decided to do away with one of the rings and all of the original bearings and lateral supports. These never worked properly and the dome used to bind when rotated.

Instead the top of the wall would hold the axial and lateral nylon wheels. The dowm would have one of the metal rings fixed to the underside. This would ride on top of the wheels fixed to the dome.
