The extra plate does on the inside of the draw plate and outside of the blow plate. You have to line the reedplates up perfectly or the reeds of one will scrape the inside of the other. The extra plate has its reeds removed.  I never really tried lining them up like that, I just made the free end of the slot bigger so the line up didn't have to be absolutely perfect. 
Set up is about like anything else. best attached with bolts, nut and lock washers. Oh yes, both plates need to be convex. 
This works better on low harps,

Geez 12 years on Harp L and i am still hearing about things Harmonica that 
i'd never even thought about.(great eh)
First fjm and with his embossing and now Davey (Crockett) as per below.
(dumb questions) How do you exactly double plate a Harp?
            I assume that only one plate has reeds on it?(duh)
            Does this plate go on the bottom or top?
Please just tell us how you would set up a double plated harp.I'm keen to 
try it as i have a plethora of spare reed plates.Most of which came about 
'cos of my embossing experiments.;-)

There's bood good and bad about having thicker or even double thick plates. There is going to be a difference as to how a reed plays with the standard 0.90mm thickness and 1.07mm, and even more so with one that's 1.20mm thick (as what's on the hering 1923 vintage Harps). The thickness will make a reed play louder and much more aggressively, but the HUGE drawback to it is that if you're more like the stereotypical diatonic player who uses an excessive amount of breath force whenever you play (AKA playing WAAAY too damned hard all the time), the risk of blowing out harps quickly increases dramatically. If you also add in a much tighter reed slot tolerance (which also makes a reed do much the same) on top of it, that possibility will get magnified, and most diatonic players tend to be anything but gentle on their harps.
