  • warpage

    I have a 4 lane scalextric track that has become warped at the sensor area (photo is currently on the camera sitting on my desk at home!). I am in need of either a replacement or suggestions on how to take the warp out. i'll post the photo later.

    Example of what I am talking about

    Very nice dip right after the sensor just before the next joint.

      Massive amounts of weight over a relatively long period of time. By massive I mean around 20 kg (50 lbs) or more. A small amount of heat from a heat gun on a lower setting will help the plastic get back in shape. The rails you may have to put into a vice.

      To be honest, if this were a standard piece of track I would simply replace it as you will never get it 100% flat.

        It is the sensor track piece. I'd have to rebuild it or order another

          I was wondering if the track sections were still being made, this forum has been inactive for quite some time.
          Are you using Scalextric track? We had problems with that developing warps over time. Flattening out a section with sensors in it would be a more delicate operation. Since you are also getting bogus readings you might replace the section with a new one if those are still available.

            Yes, Scalextric Sport. I figure any warpage is from when racers put their weight on the track. Need to come up with a new lap counter. Not a fan of light bridges...

              The track can warp all by itself. All of the Shoreline Model Raceways tracks are now wood. Our last plastic track was smooth when it was new but it developed so many warps that we started to call its owner "Lumpy", a nickname that persists to this day.
              The track warps because of stresses from the injection molding process. Those are probably due to the sections being cooled too quickly. If you just put weights on the track you can flatten it out, but since the stress is still there it is likely to warp again after a while. To remove the stress the track would have to be annealed, that is heated to the point that the plastic starts to soften, then cooled very slowly.
