Tower Base

In order to be able to lift the heavy conning tower base up and onto the hull to mark ready for cutting, I had to rig up this scaffolding and chain hoist.  The ring is to heavy to lift without help, but once on the chain, its easy to move it round into the right position.   I had to weld a bar onto the top of the ring to suspend it on the chain.  I will cut it off later.

I’ve used a plumb line to make sure that main weld is exactly at the top, and a spirit level to ensure the tower base is level, relative to the hull.
