Five of us at Broadway today to do some preliminary layout of the cranks on the steel plates at the exit of the signal box tunnel under platform 2. and to continue with work on the locking frame.
A bit of freshly laid ballast to be scraped away and a couple of holes prepared for the two rodding stools which we are temporarily inserting to line things up. Keith L just loves shovelling ballast. A few of the fittings are lined up on the platform:
We have now marked and pilot drilled the four holes for each crank base . When we have set a further three cranks for the southbound rodding and the pulley wheels , we will remove the plates and use the magnetic base drill to open out all the holes for bolting. (not enough headroom to get at these holes with it).
These four northbound rods will operate the two points and two facing point locks. Levers 12,13 and 15,16.
Unfortunately rain ended up stopping play by mid afternoon so we repaired to the locking room to admire the efforts of Malcolm and George bringing the locking frame jigsaw to a conclusion. All locks and locking bars have now been fitted and subject to a bit of easement here and there it is now complete. Only remains to do the testing to make sure that all the locking combinations work.
The pictures put on today are brill' well done, for the pictures and the work being done.ReplyDelete
Very complicated looking but impressive too.ReplyDelete
Great photographs and a welcome update from a lot of other stuff that is going on at the moment! Regards, Paul.ReplyDelete
Interesting stuff, certainly need to know your Pythagoras, but what happens when the Ballantine is done through the station, would it not cover the ridding?ReplyDelete
Ballast, not Ballantine!ReplyDelete
Thanks for keeping us up to date on your work, we are sure your slow but steady work in the signal box interlock system and the rodding will work perfectly first time! Another great effort, and good pictures as well!ReplyDelete
