Re: die/punch alignment for kickpress and thin material

The result will be something in the middle with less but still some misalignment. Or is the die set mounted so that only downward pressure is transferred to the die set? I have seen some small punches that are pressed down with a ball bearing so that any flex is not transferred to the punch but doubt that is common.
I have a large'ish fly press and there's no flex at all in it, but as others have pointed out a proper die set will eliminate any alignment issues anyway. As you asked above, the press will provide downward pressure and die sets are normally bolted/clamped to the table, so any sideways movement doesn't usually matter at all then.
