This weekends first 'why didn't I think of that before moment' came when I was setting up the router to do the beadings and glazing bars. That was simply to change my 2' quick clamp to a spreader to act as a router lift.
Having made a whole bunch of mouldings I had the 2nd WDITOTB moment of the weekend, in as much as it seemed it would possibly be a good idea to knock up a rudimentary drying rack of sorts.
I don't know how I ever got by without one before.
