Frost sticking wheels to rails, anyone?

As an experiment, try a dew type heater wrapped around the motor body. If left on whilst the roof is open it should provide enough heat to stop the motor from freezing up if that is the problem.

Tis struck me as a possibility as well. Worth a try for sure.  I'll just have to be careful about where the cable goes since it will have to follow the roof.

all you need to do is apply Vasaline to the rails and wheels  it will protect against moisture and therefore wont allow frost to get a hold, and it will keep it running smooth.

i had a similar problem with frost i have garage door draght excluder on the bottom of my home made dome (the brush kind)  and it would hold a little bit of water and would stick when it got frosty, i have now coated both brush and flat roof with vasaline and no more sticking.
