Thanks Jay.
I could only get one of your links to work but the pictures there were enough to get me thinking and to answer the question myself. The only challenge now is to put it into practice.
...and thanks Will
Read the article in Timber Framing a while back but don't recall that it detailed setting the reference heights, only the actual scribing process, but I am pretty sure that I will manage now. If I don't and stuff up it will be into the workshop again to make up a couple of nice wrought iron saddles to carry the post. Either way it's good fun learning although I often wish you guys were just up the road rather than on the other side of the world.
Cheers
