side hinges

Sep 28, 2005
When are side hinges nessessary, and are there any risks or disadvantages to using them?

I'm floating a somewhat heavy paper, about 25 x 30 inches, with pass through hinges. I'm using the stroger type of hinge where you paste two pieces of tissue together in the form of a "T", if you know what I mean. The paper is similar to a 200 lb. watercolor paper.
They're usually used to control curled paper at the bottom, especially when doing a float mount. They'll keep the bottom of the paper down somewhat and prevent contact with the glass.

There shouldn't be any downsides to them as long as you attach them a bit loosely so that the paper is still free to move as it wants to expand and contract.

As far as the hinges you mention, I know what you mean. Hugh Phibbs covered it in one of his articles a while back. When it's doubled over like that, it's a jumbo hinge. The T shaped one, not sure what the term is.

Kudos for taking the trouble to hinge properly and not being thempted to use linen tape.
As Dave says, the bottom will keep the piece for curling up to the glass, and prevent any lateral movement.

I echo Dave's kudos for the jumbo "T" hinge... linen tape is for filming fields of flax on VCR.
On the FrameTek web site under the pull-down menu titled "Free Info" there is the new instuctions for FrameTek's Nori ready to use wheat starch paste.

These instructions explain exactly why side as well as bottom hinges are recommended even on very light pieces. It all has to do with hinges in the "Shear" mode (very strong) being turned into in the "Peel" mode (very weak) by the frame job being turned sideways or up-side-down.

Remember that museums are in a completely different business than framers. They need to see the back side of artwork (hence hinges just at the top) we need to have the artwork stay hinged and aligned with mats regardless of how the frames are mishandled.

Check these instructions out and if you have some helpful ideas on this subject, please share them with me.
Greg- glad to see your post backing up my thinking on that. I always assume the worst about how the client will handle the framed piece (despite our instructions to the contrary) between our shop and their wall. The folks at the museum will do it right.
:cool: Rick

P.S.: This same phenomenon must explain why, when visiting customers' homes, we often find framed artwork hanging from one hook, despite our explanation and providing two.
I don't know what kind of barbarian would use linen tape to hinge art. That's much too strong, and the adhesive, whether it’s gummed or pressure-sensitive, is less than ideal.

Thanks for the advice guys.
