This month's tool is the Moxon Vice!
Having quite a narrow clamping capacity (just over 50mm) the main task this vice excels at is clamping wide boards for cutting dovetail joints. There is enough space to fit a 600mm wide board between the two screws.
I made mine using the hardware and plans (which I modified) from
American company Benchcrafted.
Here's a short gallery showing construction of my vice.
The moxon vice has been extremely useful while preparing, marking out and cutting all of the 40 through dovetails.
Here are a few photos of the vice in use.
