what kind of hinges...

[worriedshrimp]

greetings GJ,

i'm building a table top that one end (approx 1/3) will lift up with hinges. the table top is two 3/4" pieces of birch plywood glued together for a total of 1 1/2" thickness.

the portion that lifts on the table is heavy with 1/2" rubber matt glued to the bottom. a standard piano hinge will not be adequate.

i would like the seam i cut and the hinges i install to be as flush as possible. i'm trying to find the correct - offset x 1 1/2"? -hinge and use four of them across the 36" width of the table.

can anyone describe the type hinges i need for this job and where i might find them?

thanks for any input.

Sounds like you want a drop leaf hinge:

Mortise the hinge plate into the surface for a flush fit.

thanks turbo,

but the hinges i require must not be seen on the surface of the table top... they need to go down the inside edge and wrap under the bottom a little i would like to screw the hinges from underneath. i just don't know what they are called.

Pretty sure those are mounted on the underside of the table and mortised in place.

Not sure how this link will work but if you can open it, the KPeterson picture shows the hinge in place.

can't find an outlet for a hinge like this that is 1 1/2" deep

mine is not a drop leaf... the portion of my table top has to lift UP.

You might try Mcmaster Carr, or how about taking a strap hinge and bending the two leafs to resemble back to back Ls?

Sorry, I didn't get that from your first post. I'll keep thinkin'.

You could use a "Soss" hinge.

Or, take some standard 1 1/2" **** hinges and weld on the extra 90* support leg.

So you're wanting a tight seam on the tabletop with no gap and no hinge showing, and it has to hinge upwards?

That defies normal physics. You'll need to build a custom two stage hinge system

lilredex is right. SOSS hinges will work.
