Bristol Barrow Road - Making a few points
The layout is not operational at present as all the power supply units, NCE equipment and circuit breakers are elsewhere for fitting into two power boxes than are being made for me - thanks again Chris!
In the meantime I decided to make a start on the B7R and B7L turnouts for the storage sidings. I am using 4mm wide x 1.6mm thick copper clad strip for the sleeper timbers and Nickel silver bullhead rail.
These series of photos show the latter stages of construction. The timbers have been laid out on templot templates the 1 in 7 crossing V constructed and soldered into position followed by the straight and curved stock rails. We pick up construction with the first of the wing rails. In the photos left to right are - DD Wheelrights Jig for crossing alignment - two three point track gauges and a Roger Sander 'Mint gauge'.
To the front is a jig for filing up the 1 in 7 crossing V. It also will do 1 in 6; 1 in 8 and 1 in 9.
The DD block gauge in use to set the wing rails.
The Mint gauge is used to check tightness in the track gauge. If tight the soldering iron will assist adjustment.
Three track gauges in use to hold the closure rail/switch blade in position.
Wing rails added.
Soldering the blades.
The completed B7L
Five made so far
26 to go!!
