Here is the new way I mark large radius curves with my beam compass, have tried using a tape measure, all I need is to  make an adjustable beam , have in the past marked out 6foot radius curves.











The last pic is the pivot end, I put it in an inch from the end of the beam, this curve decking is for the end of the lower level of the spiral four foot radius comes around onto a 6foot bridge and the back corner module after that module is the 27foot bridge.

The bridge be modelled on the Denmark to Sweden double deck cable stay bridge, I will be using 5mm dowel for the cables be 40 on mine the bridge isn't to true scale be 5metre span in HO scale and there is the approach sections on each side.
