What held this bike up for so long was the Shimano Deore XT M8100 right hand crank with a Power2Max NGeco spider and Woftooth 34 tooth round chainring. That was supposed to be it, no modification needed, but Shimano have shortened the axle and slightly altered the splines on their newer cranksets. These things are never straightforwards.
In order to make it work the steel crank axle was wire cut in half and then half a Shimano Deore Crank axle with the correct spline and length for a Shimano Deore Crank was attached to it. In this picture the piece of metal at the bottom shows the test cut. The axle has a reinforcing steel sleeve inside and a bolt through the middle so there's no way this is coming apart when riding!
That means I can attach my custom swing crank, based on a Shimano Deore left hand crank, to the Shimano Deore XT right hand crank making the bike fully rideable at last. This lets my paralysed left leg just rest on the pedal and spin small circles whilst I do the actual pedalling with my right leg
