Back to the track this evening and a little more trial and error with the V on the B8 point. I now hope I've produced something that will work OK. The rail seems firmly fixed, there's electrical continuity between V and wing rails and, to my amazement, a wagon will roll effortlessly through it. For the amount of time and effort I've put into building this V this is all very satisfying.
The technique I've used is to glue to the sleepers some of Bill Bedford's brass Point Slide & Special Chair etches to which I've soldered the V and wing rails. This has been the trial and plenty of error bit. Very little of the brass etches are visible either side of the rail which has tested my soldering skills to the full. I'm getting good at burning sleepers! ....... Hope the joints hold up when in use as I've only soldered one wire dropper from the V and will be relying on the brass etches to transfer the current to the wing rails. Next time I scratch build a point I might consider soldering some wire droppers on to the wing rails. The chairs around the V still need to be installed but this will be done later when I'm fully satisfied with the whole point.
The photo below is of my trail run for constructing the switch blades and might help to explain the above technique.
The above photo shows where the brass etches will be glued to the sleepers. I'm hoping that two soldered joints will be sufficient to hold the switch blade in place. Use will be made of brass fish plates at the joint with the closure rail. This should help secure the switch blade in place and also help with electrical continuity between them and the closure rail.
Any alternative suggestions to the above will be gratefully received........
