So all that batch work I was talking about in my last post (which was a while back)... is the 'Airfix kit of parts' I first made.  It took a while as there were 416 individual pieces.

Looking at the picture, it is not clear if I was making a Lancaster or a Spitfire. Neither. The answer is trays with little sub this finished one.

I was actually making a batch of 30! 

So making a big batch like that does show that some tasks are quicker, for example when wood is machined in bulk. But some tasks take just as long, for example when a tray is glued up (there is a slight speed gain, as after making about five trays, the best order and method is found).

So there you go.

Time and motion studies.
