Kev...
A little tip....( sorry if it sounds like teaching granma to suck eggs )
When cutting the compound angles on SB5 & SB6......totally ignore the 17degree "View B" in the cutting diagram on page 166,
the 17 degree,s is what you actually end up creating by making the compund cut 52 degree,s / 27 degree,s.
lay the tube on the table in the position as in the diagram, bottom sketch, ( as you have already cut the 52 degree angle) then turn the steel 1 flat away from you then scribe the 27 degree angle on the uppermost face( upper sketch), then turn it back 2 flats towards you, scribe the 27 degree line from top right hand point of the steel ( scribe line goes from top right down to bottom left ), then turn steel 1 flat away from you and use a steel ruler to scribe the 2 lines together.
When cutting it, cut each scribe line on 1 flat at a time, turning the steel in the vice to complete each cut......result = perfect compound angle.
Hope this helps,
The other side is in opposite hand.
