« Part 1: Clam Shell Hinges - yet another different wooden hinging method Part 2 of Wooden Hinges series Part 3: Retrofit - making the new hinge »

We all make mistakes. Yes even me. I’ve been working on the design and build of a box for the best part of a month and a half now. You know I don’t like chunky boxes, the sort with way too thick walls. This box is about 125 mm square x 75 mm high. So I’ve made the wall thickness 6 mm, slightly on the thin side but not a problem for a shell or drop on lid box. Except this one has a wooden clam shell hinge (see first part of blog). This was a mistake

as the consternated look on the back of this box shows.

I tried to CA glue the broken pieces back in, to try and fix it, to no avail.

The weight of the box lid is too great for the size of hinge. The grain direction was also wrong.

Now its an anamorphic patterned, EZ Mitre box. A lot of design and build time went into it. I could have cried. I swore a lot, in several languages.

So I had a long think. One of my 3:00 am in the morning, long thinks. I came up with a new angle on what is basically an engineering approach (thank you MOD (DOD) training), retrofit hinges. This is the basic design

The top and bottom are 6 mm long, 2 mm hidden splines which will be buried in the box back (with 2 mm of back material on each side). Here the hinge is at various degrees of ‘opening’ seen from outside

and inside

The ‘meat’ of the hinge is 9 mm across and so much more substantial. The extra 3 mm of hinge will protrude from the back of the box. As its curved this should not look too inelegant. I’ll rescue the original 2 mm brass pin from the box as I will be cutting out material to give room for fitting the hinge as well as routing out slots for the splines to fit into. I’ll detail the make on the hinge as well. This is the type used for Pac Man, an earlier box.

To start I’ve cut and thickness sanded a piece of 4.5 mm Ebony

Cut into pieces 60 mm long

Re- arranged for correct grain direction for a wooden hinge

and glued up and drying, as I blog.

Are you sure Hank done it this way?

Thats all for now.

Be seeing you.

These hinges look very good to me Martyn. It is worth all the time and trouble to come up with something so attractive and useful at the same time. I’m looking forward to seeing them fully constructed and then in action.

Martyn Shirley says that I only make two mistakes
All I say and all I do.
I think those hinges will be a lot better and it is the
delicate detail that you enjoy.
I wait for the next part.

Yes Jamie. Reminds me of the old joke.

It’s good to know that you are human after all! I thought you were a box making machine. Your ‘fix’ looks like another brainstorm to me. Is Hank popular in the UK? He’s one of my favorites.

Country is not very popular here but I liked the Waylon Jennings song about Hank Williams. I find it doesn’t really matter what sort of music you prefer, there are always one or two good songs in other genre out there. Mostly like Rock myself but am also partial to the odd classical, Glenn Miller, Folk song etc.

Waylon is way up toward the top of my list (but you were pretty certain I was a country fan!). I admire your perseverence in fixing your current project. Best luck and keep us posted.
