Pictures 50 and 51 show the supports for the (now higher) cam. Thanks Adrian – I was aware that I had shot myself in the foot by putting that girder there at the front originally, but I was just keen to get something working that was at least better than the ‘suicidal’ original design, and planned to put that right later, which I have! So now this arrangement works, and doesn’t clash with the original design. Don’t we all just love a couple of married 19 hole strips!
