Hi Jamie,
Thanks for your feedback. I must confess my colleague Simon is responsible for much of the larger steelwork. The oak stump was from Seahenge, a beach based wooden circle. It was extracted from the sand and we had the problem of displaying it in the correct orientation. An A frame would not allow us to get close enough to the wall, so an adjustable frame needed to be fabricated so we could maneuver the stump into position and fine tune the mount. This allowed us to position the mount on the wall and secure the stump.

I would love to be able to attend the 2014 Forum, however I just can't really justify the expense and time off at the moment. I will try to follow what I can online. Thanks for the warm welcome.
Tony
