Firstly a google search is useless as I have no idea what they are called. So I shall describe the project and you can fathom it out.
I'm making a ring binder out of cherry. This will work by using brass piano hinges the neccesary points. Brass trim along the exposed edges (as i'm using cherry vennered Ply). But instead of just mitring the brass channel to meet at the corners I was thinking about those thingies/do hickies that cover corners. I've seen them for cabinets but they have three side for mounting and I only have the two. I hope i'm making sense. I was aiming for either 1/8 or 1/4inch thick but i think
1/4 will be too thick.Thanks for any help
