Hi Tony,

Here's what I made it. 56.5 degrees from the vertical as measured on an existing pipe. I allowed for the ferrule at the thermostat end and a bit of a bow in the pipe at the bend.

Probably if you were out by a few degrees it would not matter and knowing how draughtsmen think it probably was designed 60 degrees off the vertical. That way you can use your 30-60-90 triangle to keep it simple when drawing it up.

Cheers
