My more modern Points which have no support under the operating tie bar at the outer sections have been giving problems with poor contact electrically and more recently dropping the blade sufficiently to allow wheel sets to drop off the outer rail (this is always manifested on the curved blade rail.
The blade is set some 40 thou above the sleeper surface so I have been experimenting with various arrangements and materials to overcome the problem.
The result was 40 thou PVC strip, cut to the width of a sleeper and
18mm long ( just sufficient to sit under both blades when aligned with the nearest sleeper to the under side contacts and held in position with a spot of super glue). Silicon oil applied between the sleeper and the new tie bar ensures freedom of movement coupled with sufficient strength to support the blades under load.
I have discovered the ultimate test vehicle -- it will object to the slightest imperfection or sample of shoddy work or poor design -- the Mainline Class 45 peak!
Has anyone else had this experience with their points ? My older peco units which have a built in longitudinal tie under the extremes of the operating tie bar do not suffer like this.
