After dissasembly I removed the central moulding on the plastic throw bar and at this position drilled a small hole and inserted a shortened pin. Some CA glue keeps it in position.
Next a slot was drilled and filed in the plastic cover plate so that the pin could move the throw bar from side to side without obstruction. This area was then reassembled without the magnets.
Two holes were drilled through the existing mounting mouldings. One for the plastic cover plate and the other the PC board. These along with other additional holes are where the plastic spacers are secured to the turnout using T Gauge track screws.
The plastic spacers that the servo is mounted to are thicker than required. This has meant that the servo horn is not as close to the base of the turnout as would be ideal.
Here is a video of T Gauge turnout operation using a servo.
Plans for the next version would be mounting the track and servo to a base board of the correct thickness. This should help keep the track flat and eliminate the flex experienced by the existing setup. Also changing the servo horn position so that it is connected to the throw bar via the furthermost hole to give a wider radius. Hopefully this will decrease the movement in the axis perpendicular to the movement required.
