Today we were delighted that the four authors of the papers that filled the latest edition of the International Journal for the History of Engineering and Technology (Vol 92, No. 1 2022) were all present on site. (See for details of how to obtain a copy, or contact Geoff Wallis ( for one). There was lively discussion about Brunel's design. and in particular the post-tensioned tie-rods inside the 'balloon' section of the spans. Andrew Smith, Bob Watkins and Dr. David Greenfield used our endoscope to investigate the method of fixing and tensioning the rods, and their condition.

Meanwhile our seven other volunteers continued restoration work on the Brunel Lock capstan, and trialled Julian's plate-lifting 'Lewis key'. The expanded gardening team removed four Buddleia bushes and the substantial root of a tree that had grown into the copings of Brunel's Lock. We are seeking the Council's permission to remove other trees that are getting established in the masonry here. Eventually they will dislodge or damage the substantial masonry blocks, which will be a considerable expense to the Council to remedy. Altogether a productive and enjoyable day in the warm sun. Do come and join us on May 20th. It's fun! and we would appreciate your help.
