I promised to work a little more on the wooden hinges, to see how I could improve the form, the shape, their appearance. This is what I finally glued to the box:
The rounded and lightly lifting distal edges provide a nice shadow line on the lid and on the back of the box – a pleasing, subtle effect.
I frequently participate in some of the online woodworking discussion forums. I shared an earlier version of these hinges on WoodNet, and many questions/suggestions resulted on whether the bottom of the lid would drag on the edge of the box, in this hinge configuration. I had a gut feeling it would not; but some suggested it might.
To be safe, I rounded over the bottom edge or the lid, along the edge where the hinges attach. I also recorded a short video, to see for myself and to share my findings. In this hinge configuration the lid lifts right off the box easily, without dragging on the edge of the box. Did the roundover do this? Or did the high location of the pin cause the lid to lift like it did? I will have to go back and try a lid without the roundover, to be sure.
In the meantime, watch the video below, and let me know what you think:
- Is there cause for concern that the lid will drag on the box if the edge is not chamfered or rounded over?
- Is the location of the hinge pin responsible for the lid lifting cleanly, as we see in the video?
- If someone fully understands the mechanics involved with this hinge design, please share it in the Comments section. Thanks!
