Im going to be building a 4 compartment box with 4 lids. Normally I use piano hinges and air loaded hinge stays , like the ones in your hood of your car or back lift gate.
Seems as though these http://www.rockler.com/product.cfm?page=21288 would replace hinges and lifts. I understand they dont open up the same. Any negatives on them? Like if they stay tight against wood lid rest on when closed or do they want to stay sprung up say 1/6th?
Thanks
