Further thoughts on the above .

The firm in / was in Glasgow is CHARLES McNeil Ltd and I think they are now part of Motherwell Bridge Group . I seem to remember talking to them about Manhole Door bridges awhile ago.

Another possibility is ABBOTT & Co Ltd . in Newark . They make and supply components for and manufacture air receivers and pressure vessels . Might be worth talking to them.

Another suggestion is to machine it as a `one -off ` from a thick piece of plate on a vertical CNC machining centre with a 4th. axis.

I would be better to start with a thick piece of plate rolled / formed to the approximate radius ( by Deepdale in Dudley or Barnshaws in Wolverhampton ) . This would save on the machining time and it would then be a relatively straightforward job on a suitable CNC machine to machine from solid all the detail and the required radius .

Still not a cheap project .
