You will very pleased to know that Laurie Smith is coming your way in the next few months. North East I think.
Go and meet him. Offer him curry and beer, sit back, listen and be amazed!
He did a fair amount of work with Adrian Gibson on Cressing temple barns and has a also found similarities with the layout of Ely cathedral.
There are daisy wheels scratched beside the fireplace at The Queens Hunting Lodge in Epping, these are as someone said credited as being ritual marks. No mention of layup or design.
I think they could be something as simple as an apprentice scratching the daisywheel out on a post that he knew would be covered up… idle hands and all that… or the master carpenter leaving a signature as to the design of the building.

The building that the above daisy wheel was used for is this one:

I think a similar arrangement was used for setting out the footings/plan. I didn't take part in the cutting, just joined Laurie for the cladding over a few winter weekends.
