Torsion hinges

I have no experience with hinges but just built a crib for my grandson and used 250# capacity adjustable feet on all four posts.

When it come to grandkids you can’t overbuild.

Sort of a disappointing response, but I have answered my own question. I mounted one of the hinges on a couple pieces of scrap to test how much force is required. Glad I did. There is no way these will work – far too much resistance. One would be fine; two is too much.

I would just use one of them on one end of the lid and a non loaded one on the other end.

Going to drive up to the Rockler store in Tukwilla (about an hour north on my home in Tumwater) and exchange them for a lighter pair. Using one would have been a good idea if I had a non-loaded matching hinge, but I don’t. Besides, these things are expensive, I want two I can use.

Unless you have tested them against the actual weight of the lid, I might not be so quick to return them. They seem extra stiff in testing or just trying to do them by hand. It has been my experience with them that the more resistant, the better. Lids put a lot of downward force on them when in a partially open position. I think it is more desirable to have them too stiff, vs too easy. When kids will be using it, slamming is a concern.
