Also thought as quite a resorceful thread I'll add some extra photos...
Drilling the holes to fit hinges to the doors, after looking all over for the measurement to drill these and finding a blum tech sheet, i drilled my 35mm holes (with a forstner bit) 22.5mm centre from the edge of the door panel, 4 inches down from top/up from bottom. Got to be quite careful as the holes needed to be about 14mm deep (in 18mm door) and with a small pilot bit on the forstner drill bit, it almost came through the front of the door, this will depend on the drill bit you use.
I then fitted the hinges to the doors.
After screwing the hinges into the door I fixed on the mounting plates (that screw onto the cabinet sides) and put all hinges in closed position.
To get the correct position for the mounting brackets was simply a case of propping the door in it's closed position against the cabinet, using screwdrivers, scrapers, bascially anything I could to pack it out into the position it would be in when closed. Once happy with all gaps at the side, top etc, I drew around the mounting plates on the cabinet sides with a pencil, then removed the mounting brackets from the rest of the hinge, put them inside my pencil marks and marked the centres for the mounting bracket screws. I believe you can get a blum mounting template that does all this for you. *Note - doing it the way I did, i got a good fit, but did have to use all the hinge adjustment available to get the doors flush to the top panel so in hindsight I should have set the mounting bracket 2mm back from my where my marks were, but hey, it's worked out ok.
I then offered up the left hand door whilst the right hand door was still on, to ensure gaps between the doors were good, once lined up and the left door gently packed and held in position (as the right one was) i removed the right hand door so i could get in to draw a pencil round the brackets for the left door. I then just did the same for this door as the other (so again had to use all adjustment for getting doors flush!), and when all done...
Da-daaaaaaaaaaaa
