Project 17 - Rodding Commences

Now for one of the more tricky parts, not only in model construction but also for prototype technical understanding. I confess to being no expert and have spent ages reading up on technicalities and reviewing photographs of the location to identify turnout rod runs and cranks. The cranks can have one of two orientations and I don't know if my guess is correct as I cannot determine it from the photographs I have.

The stools (rod rollers) in this first section beneath the railway bridge in the photo are my last stock of the defunct Colin Waite brass etchings. All others will be the Brassmasters version. The cranks are a mix of both ranges. I have used round copper wire for the rods, whilst round rods were used on the network I believe at Swanage they were square channel, the other option. The spacing of stools for round rods is eight feet.

The installation is purely cosmetic and will be painted when all is finished. Needless to say this lot is quite fiddly/frustrating to assemble but I get a weird sense of enjoyment threading the rods through the finished  stools.

Six rods control two catch points and three turnouts. All together that is five turnouts so why six rods? Each rod is associated with a lever in the Signal Box and they were allocated as follows:

Lever 10: Shed road catch point
Lever 9: Goods turnout
Lever 8: Facing Point Locks of  No2 road and Goods turnouts
Lever 7: Siding catch point (off stage) 
Lever 6: Two Facing turnouts on No 1 and No 2 roads
Lever 5: Facing Point Lock for No 1 road turnout
