"Oldest buildings" or, as we say, "recent".
The Belfast dendro project was inspired by piles of bog oak drag-lines out of bogs when the NI M1 was built. Bog-hardened and sun-dried they were no fun to cut with a blunt Bushman saw. A chainsaw was an early acquisition.
We were offered the chance to whack the end off a floor joist that had been exposed when some work was done in Trinity College Dublin Library. Sadly, you can't use a chainsaw in a library so it was back to the Bushman.
In retrospect starting a project like that and expecting to get back from modern to those bog oaks was sheer bravado but Mike Baillie made it work. RIP, Mike.
