On my Signals Branch blog I have just added a link to a PDF file that outlines which Signal Arm and Detail Part Sets to use with particular signal posts.
I have just had someone (unfortunately unknown) order a Triple Bracket Post signal with the arm and detail set for an Inverted (underslung) Bracket Post and this will leave the modeller short by one cast iron support for one side of the bracket.
Of course it may be someone who has previously ordered the double set of bracket detail parts and as such has the necessary parts.
However this did raise a question of how does someone with only a little knowledge of signalling work out what to order.
Here is the document Matching Signal Posts to Signal Arms and Detail Sets.
The document advises that the modeller refers to the NSW Track and Signal Diagrams CDROM available from the ARHS NSW online bookshop.
Signal Assembly service
If you want to order signals from my Signals Branch Shapeways Shop and you would like someone to paint and assemble the signals then Dale Richards has indicated that he will assemble them, for a price of course.
Dale's email address is firstname.lastname@example.org
Dale also makes his own signals using brass etches and tubing for round posts so he would be glad to speak to you regarding these as well.
Shapeways Shops Now Show the Price in Your Currency Recently Shapeways made a change to the way that the price is shown.
Previously the prices on the Signals Branch Shop were shown in US Dollars but the price is now shown in the currency of the country that you come from so Australians will see the price in Australian Dollars.
Shapeways still operates in US$ behind the scenes so the price is set in US$. A by product of this is that the exchange rate causes the price to look like an odd amount.
