blum hinges for 1" thick inset doors

[jim mills]

Help! My blum info is a stack of random printouts, old catalogs, drawings, and post-it notes with UN-legible chicken scratch.
I'm using the excel spreadsheet, and it tells me I need a 71b3650 hinge. I've got some 71b3750 hinges on hand. Can someone tell me the difference? Thanks! Some days, Blum just gives me a migraine...:(

Face Frame or Euro?

[jim mills]

Face frame.

[Gerry Grzadzinski]

3650 is a half crank.
3750 is a full crank.

The 3750 won't work with the face frame plates. It has 9mm more offset.

[jim mills]

Would either work if I did a pack out instead of using the face brain plates?

Yes........

With 3750 use a 0 mm baseplate with pack out flush to frame

With 3650 use a 9mm base pack out flush to frame OR you can pack out 3/8" (approximate 9mm) from edge of frame and use a 0mm baseplate.

Really appreciate it! I feel my migrain subsiding...
I can usually figure out what blum parts to use, but none of it makes sense to me, therefore I just dont retain any of it.


EDIT: Bill, is this backwards:

"With 3650 use a 9mm base pack out flush to frame OR you can pack out 3/8" (approximate 9mm) from edge of frame and use a 0mm baseplate"

Don't see it as backwards. Care to clarify?

[jim mills]

Bill. Kinda hard to put in words, but isn't pac out flush to the frame is same configuration as frameless design? In that case wouldn't i use a 0mm base plate?

Wouldn't leaving the pack out 9mm shy of the face frame require a 9mm base plate to bring it flush?

[Bill Orbine]

Jim........ I'm afraid you are getting this all backwards yourself. I wish I can give you a visual interpretation of my description, but I don't have time now to draw one up or search for one online. Maybe later or someone else can chime in. But you are confused with my explanation using a 3650 hinge which you don't have. You did say you got a 3750 hinge. Full cranked. Let's focus on that.... shall we? Does my original description using 0mm baseplate make sense to you?

[Gerry Grzadzinski]

"OR you can pack out 3/8" (approximate 9mm) from edge of frame and use a 0mm baseplate"

What he's saying here is to pack it out so the blocking extends 3/8" into the opening. This is not typically done, but it would work.

Assuming that you mount the hinge plate flush to the face frame, you have 3 options to get an inset door.

0mm plate and full crank hinge.
9mm plate and half crank hinge.
19mm plate and standard hinge.

You have the full crank hinge, so you want a 0mm plate, installed flush to the opening.

[jim mills]

Ok, so in summary, the mechanical function of the three hinges is basically the same, but the "crank" determins the reletive position of the base plate.

[Gerry Grzadzinski]

Yes. The different hinges allow you to use the same baseplate for multiple applications. We usually keep some 9mm and 19mm (18?) baseplates on hand so that we can use the same hinge for multiple applications.
(we mostly do full overlay doors).
