In the pic below, the flat on the corner style to accommodate the top and bottom is:
... being chiseled flat with a nice sharp Japanese paring chisel and is shown:
These wretched corner styles have to be planed with a small radius, easily done with the Veritas LA jack, but not so easy to hold the frame, until I realised that many moons ago, when I built the bench, I also:
...had the unimaginable and utterly brilliant foresight (which you'll have to agree is about as rare as bloody hens teeth!) to have a section of the bench well that was removable. This means of course, that you can use a cramp from both sides of the top.
Sometimes, my undoubted genius is enough to make my head spin...had I been recruited to work at Cern, the Higgs-Boson would have had to be renamed as the Bloke-Boson!
With a lot of care, the basic carcase went together quite well:
...though it's not quite square, so I'm hoping (fingers and all other appendages crossed...again) that the top and bottom will eventually pull it into alignment.
On a completely different note, Fujiyasu-san (the Swordsmith) gave me a couple of bits of timber. The first, shown below is quite heavy and is called 'haze' (pronounced 'haazeh') but the...
...second, shown below, is a complete mystery. It's hard, heavy and wonderfully figured, but I haven't a clue what it is.
If anyone can throw some illumination on the problem I'd be quite happy to cancel your subscription the the Blokeblog!
