I have spent the afternoon sitting under my baseboards trying to mount peco point motors. After four hours I have only managed to get one to work efficiently. How is it done? The hole is 10mm in diameter. A CDU is being wired in. The trick seems to be to get the solenoid to be exactly 90degrees to the rail and set so the switch throws the tie bar. But its a devil of a job, working blind, against gravity with screws falling out and then finding it won't throw. I'm using attached microswitches to switch the live frog. I must have adjusted and readjusted the motor a dozen times. I'm running out of expletives so if anyone has a reasonable sucessful method I would be very interested to hear it as I do not really want above board mountings. Hornby magazine made it sound so easy!
