Hello Col, yes it was a good job to do although we were under considerable pressure, all joints etc were cut off site, we worked to snapped center lines and used trig, it is spot on that way. We cross cut the beams with a very larger "hand held" circular saw, most of the mortices were cut using either a portable Makita chain morticer or a Maffel chain morticer and cleaned up with hand chisles.
The tennons were cut using a chainsaw to within 3 mm of the line then finished off with a power hand planer, the cut for the shoulders were done with a Festool circular saw running in a clamped on guide. Initial clean up of the beams was done with a Makita beam planer, and finished off with a belt sander. The posts on the undercover walkway along the front of the building were a pain in the bum to line up, they sat on short granite pillars, the pillars had a hole drilled inthe top to take an SS locating pin, they were cut and dressed at the local quarry, when they arrived the locating holes in the top were out, no two were the same, the masons were supposed to set them out but in the end that particular job was left to us as our own spec was + - 1 mm for the alignment (you can't bend large oak like a piece of 4 x 2) we used a laser level and got them all to spec in the end.
