My new stocking stuffer tool I just got for Christmas from my friend Don is a little square that has magnets in the base. It is very nice for squaring up tools with steel tops such as the band saw, scroll saw, drill press table etc. But it is also a wonderful jig for squaring up miniature projects. You know those metal boards you use with magnets for assembling things? Yes, it will work great on those for holding tall pieces in upright positions. How cool is that? The measurements are in inches on one side and metrics on the other.
It is marketed by Fast Cap
