Review on Enhanced Machinist Steel Square Workshop by Daniel Revlon

This little square would be handy if it was square. I compared it to my reference which is within a 0.0004" square and this small one was deflected by about 0.019" by just 2" at the outside corner. 0.001" but it took about 1/2 hour. So if you get the chance to make this square and don't take the time to fix it then you are here. If you are after something small and square then this might work for you IMO just cutting the dovetail accurately is not enough.
