The 'Glue-Up' and after.....

 Some stuff has been done of late on the Suda Kenji box, or is it a cabinet? It was glued up recently in stages as it's too complex to do it in one 'hit', so the image below shows the central shelf glued into the sides and even that was done in two steps to make sure it was dead square:




I'm always a bit wary of the 'open time' of modern adhesives, much as I like them as they're just too short in warm weather.  Titebond III which I've now reverted to 'grabs' almost instantly and you've got about ten minutes before it starts to set, which for a complex glue up is just too damn short! In my wisdom, I thought I'd try out some epoxy adhesive with a 30 minute 'open time'...


...which really is excellent as it takes all (or most of) the stress out of the operation. The main box or cabinet was glued in two stages without mishap:


The top and bottom were glued on separately with the job being very cunningly elevated off the assembly table by using a couple of bits of 6mm ply. If that isn't cunning I don't know what is! 

Once all was set hard, the entire box was sawn in half using a Japanese cross-cut saw; not easy in Bog Oak but even harder was to plane the end grain surfaces of each of the two boxes to a mating fit. If I mention that Bog Oak has a density of around 60lbs p.cu' you'll be able to appreciate just what an ordeal it was.


You can't see much detail from the picture above as it's like looking into the Black Hole of Calcutta, but there's roughly a 97% match, so all that's required with a very sharp, very finely set block plane is to take some very skimpy shavings to remove the last 3% for a 100% mating fit.
