Required fit for Brazing Shaft through a Hole.

[Zibraz]

What fit would you put when brazing a shaft through a hole?

I believe it's a close clearance fit (Something like a H7 g6) but I just wanted to make sure.

It seems the ideal clearance for brazing is 0.001-.005 inch. I believe H7g6 may be a bit tight on smaller shaft diameters.
