For my next O gauge project I would like to build a traverser fiddle yard instead of a cassette type. Is there a ratio for the pivot point of the traverser ?
If I didn't need to turn stock or locomotives, I think I'd favour the pivot to one end so that the track alignment would be easier and less of a curve to get back to straight.
That's nice. I developed an extended version of that for a scrapped 2mm project I was working on. It's a sector plate FY with a turntable in the middle. Lots of storage space plus turning facilities too.I guess you could combine the two and have a sector plate pivoted (black) at one end with a 'just big enough' turntable (red pivot) built into it for turning locos or individual stock items?

This is like Albion Quarry which is going to the York Show this year... with Peter and myself helping the owner Bob Alderman.I guess you could combine the two and have a sector plate pivoted (black) at one end with a 'just big enough' turntable (red pivot) built into it for turning locos or individual stock items?
Very nice piece of work. To help us understand, how about a vertical section to show the different levels and the material thicknesses used for each level?My Wantage Tramway fiddle yard has a double sector plate, with a common pivot. The whole thing is made from 10 mm birch ply, in two laminations to provide the Loco Plate recess and cross bearers, which rest and travel directly on the main baseboard.
Oh, go on... a sketch will stop me getting a headacher from working out which piece is bushed etc..The pivot consists of a series of telescopic brass tubes and bushes, around 6mm in diameter, retained by a through bolt.
It is not fair to assume that Sopwith-the-Pup knows anything about electromagnets so He cannot be held to be responsible!The gap in the sleeper is the result of inadequate forward thinking by the design dept. . An arbitrary sleeper spacing ended up with a sleeper at the optimum position for the uncoupling electro-magnet, whose pole can just be seen in the middle of the gap.
