Thanks again BentlyJ, so for 2 doors I use the 100 or 110 degree hinge, which gives me 17mm overlay, how much do you take off the center so as the doors dont rub, sorry for the dumb questions but i want to cut my doors and calculate to put 1/4” solid oak around and not have to trim any off after I have them made…....scotty

blum hinges require 1/8 in clearance to swing freely, I always recomened 120 hinges as min. degree of opening. 107 just dont open far enough, Ive been selling blum hinges for over 20 years, I see a lot of sprung hinges from the customer trying to push the door open a little further, over time the dont close properly. use the blum 71t5550 hinge and the cast plate 175h7100 or I like the face frame addaptor plate but works great on frameless cabinets also, its 175L6600.22 for the 1/2 overlay same hinge ,plate 175h7190 or 175L6660.22

For single doors, if you want a 1/2” overlay you add 1” to the opening. For paired doors with a 1/2” overlay you add 7/16 per door, or 7/8 to the opening divided by 2. That gives you your 1/8” clearance between them. 3/32nds is a nice reveal and is very achievable with these hinges. For full overlay, add 3/4” for the finished end side (the door will be flush to the out side) and 11/16 to the hinge side (1 7/16” to the door). For cabinets sitting next to each other add 1 3/8” to the width of an opening with a single and 1 1/4” to the opening divided by 2 for pairs. It’s simple really. If two frameless cabinets are next to each other and you want 1/8” space between the doors then the overhang can only be 11/16”, unless you are using something other then 3/4” material for your case. 1/2” overlay is 1/2” overlay. 3/8” overlay is if you use the old visible hinges where you rabbet out the edge of the door and it sits in 3/8 of an inch…...done sometime in the 70s I believe.

Bently, You’re right. There are different cranks, from inset to straight. You can do 3/8” – 3/4” overlay with just the straight arm. Simply change your plates. Blum hinges are very versatile. Currently however, I am using Salice with the soft close integrated. I have to say that I am liking them. They adjust up and down the same way they do forward/back, left and right. Just a screw. Whereas with blum you have to move the entire plate. If your screw isn’t centered then you lose some of the versatility. Of course if you hang it properly you shouldn’t need much, but crap happens. LOL. Who knows, maybe I’ll be a Salice man….

on the blum plates, the euro mount plates go by half or full over lay, the face frame adapter plates go by inches 1/2 5/8 3/4 but you can manipulate any of them by your hole placement, blum has came out with a few more cam adjusts plates, and the hinge mounted self closers,

bentlyj, I want to be able to go full overlay on 1 door and half overlay on the other with 1 box, on another 2 boxes ( joined together) I want to have half over lay in the middle between the 2 doors and full overlay on the other doors which would be the same hinge as the other cabinet. Thanks…..........scotty
