Mk. II Frame take offs - with microswitch/interlocking?
Posted: Tue Jul 19, 2022 9:12 am
I'm looking to use the society lever frames to handle signal and turnout actuation mechanically on my layout. I would like to use the built-in microswitch option and lastly, I would like to fit a locking frame at a later date.
Base
The instructions for the lever frame point to a 55mm square wooden base. Instructions for the locking say that a wooden base is required and details will be 'in the notes' but doesn't say any more about it. Is the 55mm square base sufficient for the locking frame to mount to the front with clearance?
Take-offs
Reading the instructions for the frame, it suggests that the upper take-off clevis supplied with the lever frame kit is superseded if you employ the locking frame. The suggested construction is to solder the take-off to the pin in the lever, so what is the process if one wants to add the locking frame at a later date?
It looks like the use of the microswitches precludes the use of the lower take-off clevis.
My assumption is I can use a 55mm base and it should provide clearance to the frame at a later date, and that I should use a soldered pin on the lever's top take-off, which the basic clevis is sprung over. When the time comes to fit the interlocking frame, this clevis is removed and the locking connection sprung over in its place. Is that correct?
Last question - can anyone tell me the relative heights of the take-offs from the base of the lever frame? I need to make sure i'll have clearance under the surface of my baseboards!
Thank you!
