This morning, we finished off the fourth wheel by drilling the holes into the foot plate and bolting the wheel together to the foot. We then shortened down all the fatter metal pipe (this is the support pole that goes up inside the scaffolding leg and bolted down) so we can minimised any extra height we would put on the tower (we are wary of this factor because we need to move the towers around and have to slide underneath any rafters we may have put up), the new length of this pipe is 110mm.
The fourth foot had its nut plate welded back onto the support pole and the threads were all heavily greased to avoid any further rusting problems!!
These are now ready to be re-installed back onto the tower when we are ready to put up another completed rafter beam.
