thread size of practice rail pedal on Weber verticlal

  • 1.  thread size of practice rail pedal on Weber verticlal

    Greetings,

    We have to replace a nylon turnbuckle on a Young Chang-made Weber-41 upright, part of the practice rail mechanism. The threads on the upper rod are fouled, making it unclear what the thread size is (so we can clean them up with a die of appropriate size).

    Does anyone know what size this thread is? We have not been able to find out from the manufacturer. (Although it is worth mentioning that Vincent Choi was very responsive about communicating and sending us replacement turnbuckles!).

    Thanks in advance for your assistance,

    Alan
