Gluing on a back

Here is the back to Johns guitar being glued, a job that always uses all of my wooden cam clamps. The pressure is spread by a shaped rim that sits around the edge of the guitar. I like using this method; every so often I think I ought to come up with a more elegant solution, but this is simple and it works. The only drawback is that the clamped guitar takes up a lot of room on the workbench, so I tend to glue up at the end of the day and allow the glue to cure overnight, ready for unclamping the following morning. I know some guitar makers like a jig,mold or tool for every job but I choose to work simply and not to have my workshop cluttered with equipment I only use occasionally.
Here is the back fully glued on and trimmed flush with the ribs. ( When did I start calling them ribs rather than sides...?) This is always a great stage in the build, as this is a fine opportunity to tap and flex the soundboard. Now I am thinking of the purfling and binding; I am going to use 4 matched cocobolo bindings that I know will complement the Amazon rosewood beautifully.
How much work will be done to day is unclear. Yesterday 20 cm of snow fell and brought chaos to a country not used to such weather. To my children's delight, their school shut because of the snow and it is shut again today, so playing outside (for me too) is the order of the day.
