Another visit to Broadway signal box today to do further work on the locking frame.
It was decided to add four further support brackets give additional rigidity to ensure that the locking trays cannot move This should do the trick:
Then it was time to make a start with the positioning of the locks. The tappet blades have many and various notches from their previous life at Aller Jn Box (like this one for example)
It is quite a jigsaw to position them so that some existing ports can be used . We are trying to avoid cutting new ones where possible because of the tedious work involved. Locks must be precisely positioned to ensure that a locked lever cannot start to be pulled because of slack in the mechanism.
Malcolm W has produced a locking scheme which we have been making a start with trying out today.
Here are some of the brass locks in position:
There are some more locking combinations to finish yet which may mean some re-positioning but hopefully it will all fit in. Once all the ports have been established, the locks will be attached to locking bars, the new material for which is now here:
Quite a jigsaw before it's all done.
Just managed to get a shot of the finished Block Shelf which was brought over last week and is now lying on the floor behind the levers. The two brackets to hang this from the rafters are currently being modified at Winchcombe. Another job for the new year to hang this.
