Pickup route depths

[Gothika777]

Can anyone advise me how deep the humbucker main pocket and the spring cavity bits on the side should be routed to on a flat top guitar which uses a wraparound bridge and has the 22 fret fretboard joining the body at the 21st fret? (i.e. I want to know how deep to route the pockets on my build)

Is there a general guideline on pickup route depths for humbuckers for various guitar design types?

I've realised the depths should be the same as an sg, so can anyone tell me the depths of the cavities of an sg (including the depth of the 'ears' ect)
