Getting my Russian shop set up

[Toolmaker51]

I've got the milling machine showing up "soon" (Russian "soon" is more of a Southern minute than a New York one). Anyway, have to get the trolley done for the hoist so I can lift the base to our loading dock, then lift the mill onto the base.



Turns out one tap is undersized! Bit of a panic. Then I tried the other tap and it's the right size. So, I've started tapping in two steps, the undersized one and the correct one. Easier cutting deep threads that way.

Both taps are marked the same, so it's not like this was intentional.

Can't recall who described this earlier, but tap sets described as under and full size seemed commonplace in Europe. Unsure about how those are labeled to differentiate.
