Here I build a tool and cutter grinder using plans and materials from Hemingway Kits.

The sheet metal parts were quite sharp and required a lot of deburring. They are all accurately to dimension and square, though.

The plans are nicely printed on A3 paper, although the dimensions are in imperial not great for my metric machines. Before starting each part, I converted all the measurements to metric.

I wasn't sure how sturdy it would be, given the many sheet metal parts, but the completed machine feels very solid.
