John,

In 7mm scale what section rail are the chairs designed to accept or is this a variable that can be changed by the user?

Hi Tim,

pre-sets:

or custom:

index.php


The fish angle on all prototype UK REA bullhead and jointed flat-bottom track is 1:2.75 , but on most model rail sections it is steeper at around 1:1.5

It is better to set it too steep rather than too flat to ensure the key clears.

The fishing faces are dimensioned from their intersect on the rail section centre-line. The head and foot depths can then be derived if needed, but you don't need to enter them because Templot calculates them.

cheers,

Martin.

Thank you for the question and I see Martin has come to the rescue, I am using C&L code 125 (I have stocked up) and I see the Scale7 stores also supplies code 125

I am happy to make you a Scale7 common crossing print or a turnout print in 33mm gauge for use with code 125 rail, if you are interested PM me.

I am a Scale7 member but model to 0/0MF gauge, am planning to go to Albury next year and if wanted happy to demonstrate the system there
