I bought a "lot" of metrology tools cheap. Came with a Noga arm NO Base. My current base the arm bolt is 8mm-1.25. The Noga arm is 10-32.
I have zero metric dies, and my lathe is imperial, otherwise I'd use brass. Considering buying the cheapest low grade 8mm bolt at the hardware store, drilling the center in a collet chuck, and tapping 10-32 through the middle to make an adapter.
But can you tap bolt steel with a HSS tap, or am I going to end up regretting this? I know cutting bolts with hss lathe bits is sketchy...
