How much should discs float ?

Ok, its not like I expect a definitive answer but .....
I've bought a pair of secondhand discs with the intention of converting them to fully floating.
These are they ....

Basically I will be replacing the wavy spring washers with plain shims, which I can machine to any thickness I like.
To cut a long story short, I'm wondering what axial clearance is normal between the buttons and the rotor/carrier.
Thus far I have failed in my attempts to obtain manufacturers specs so I was wondering if any of you folk with fully floating discs would be good enough to slip a feeler gauge in there and tell me what the clearance is.

Oh, and brakes are safety critical items and should not be messed with.

But, for the record, I'm somewhat protected by an engineering background and a natural caution.
