Thursday 6th June - Day 6 of the Explorer Cruise
I visited the R&CT Bradley Workshop, Thursday 6th June 2019, on day 6 of the BCNS Explorer Cruise.
There used to be five workshops making lock gates and everything necessary to maintain the canals, but now there are only two. It is a stark warning for boaters that in the days of British Waterways the five workshops made over 400 ‘leaves’, i.e. individual gates a year. Now according to C&RT each year the two workshops normally build 180 lock gates between them, although one of the Bradley workmen told me that it was in fact only 110 or so in 2018. The number necessary for replacement each year is apparently over 200. So you can see that as they wear out and there aren’t enough replacements being made, that canals will have to close.
When our canals and rivers were built there was no standard template for lock gates. They were constructed using a variety of techniques and designed to navigate the local landscapes. So no two locks on our canals and rivers are alike - each one has to be sized up and built to the exact specifications for each lock, and ‘heritage’ demands that no changes be made to existing styles.
An average lock gate lasts for about 25 years, and each one is built from European green oak from a single supplier, by a single carpenter, taking from two to five weeks depending on the size. So when you see a pair of gates, it was built by one man - no production line here. Steel brackets are fitted to strengthen the joints of the gate to make sure it lasts. Many of the cast iron fittings, for example the working paddle gear, are recycled and then reused on the new gates. Other bespoke metalwork such as hoops, collars and paddles are also made at Bradley. The gates are built all year round, but usually fitted in the winter stoppages, so the green oak is kept wet outside to avoid shrinkage, until they are fitted.
