Wood Hinges for Overlap Lid.

I can recall the manholes onboard ship including the watertight doors are using hinges that are fitted on the lid itsel flat and outside the sides. The pin center becomes offset that are far away from the usual pivot point. I was not successful on this with wood before because wood easily breaks on to the pin hole specially if the thickness is less than 1/4 inch.

Here is the one I discover for an easier way. I just drilled a wood on the endside using a horizontal mounted router. This will allow me to get the center of the wood just like making a dowel guided drill. Ensure that the wood is parallel with the bit… perpendicular allignment is very important. Then I cut the wood into strips (this time I use about 3/16 inc thick.)

The next point is the spacers. The measurement of the thickness will be the same as the opposite thickness. Please note that I handsaw the pieces rather that rip it with the circular saw. Next time if I will require mass production. Before cutting, the ends of the wood… The one I use is ebony…. has to be rounded of (concave).. Sadly, I could not find any router bit with 3/16 inch radius. So I made use of my roundfile and gouging tool.. Hard job as you are dealing with the end grain part.

The pin I use is stainless steel 1/8 diameter. During the fitting, I use my long rod so that I can allign easily the two hinges. Also I left the lower board of the box not yet fix so as to have a space for clamping. I use a masking tape for the cover first then take out the pin and clamp them. I use PVA glue.

I don’t recommend my style because I am a poorman here… The router was handheld…. The backsaw handcutting can be done in the TS or BS. I do think others have more techniques on using this style… Mike (Littlecope) has many variation on this style using graceful curves cut by scrollsaw.

This box made out of narra and will be as wedding gift for a Capt of a tanker. I still need to do the lid handle. This is the reason why a pattern the lid cover on how an inset lid is hinge just like onboard ship. The latches will not be used here but instead a bowlard or maybe a cleat will do… Hope I can make it before the wedding.

Till then and hope you learn something in this blog….
Have a nice day.

Excellent idea BertFlores58,

I have a project coming up after christmas that I think this hinge idea may work well with. Hope you don’t mind if I steel it ;)

Nice job,

Dave Ans

This looks like a good way to go ,but I do wonder about gluing the hinges on a finished surface?
Very creative Bert.

Nice Hinges Bert!!
If you round over the hinge “barrels” only half-way,
on either the top or the bottom half of the hinge,
the lid will be self-stopping in the open position… :)
