This isn't really a woodworking question at all, but I'm sure the crowd here will have lots of good suggestions.
I have a scientific equipment case (essentially an aluminum camera case) whose hingest open 180 degrees so that the top lies flat on the table.
I'd prefer that it only opened slightly more than 90 degrees, so the top would stand up. 100 to 110 degrees is OK, so that its own weight will hold it open.
What is the best way to achieve this? Simply add some hinges that don't open much more than 90? Any problem with more than one kind of hinges on the same camera case, as long as the axes are aligned? Any problem with using pop rivets to attach them?
Or should I take a different approach, such as adding a strap of leather (such as one of my briefcases has)?
Should I just take it to a luggage repair shop?
Thanks for your advice and discussion!
