Based on plans by Erhan Çubukcuoglu ( Is he on LJ? I converted it to inches, added a key slot to keep the tumblers from tumbling out when open, and built this prototype before deciding to use some actual purchased wood. The main sides are MDF with oak lamination, salvaged from a cabinet base’s kickboard. The sliding pins are 1/2×1/2×4 mahogany scraps from a local cabinet shop.

It’s a bit nerve wracking to glue the lid on with the pinned sides in place, because you just know that lid’s not coming off again unless everything works.

Picture 2 is all the parts, with the pins already installed into the feet that hang down from the lid.

Picture 3 shows the box and lid. The box has two parts hanging out to show how I lock the sliding bits in so they don’t fall out. The lid has two legs with pins that need to match up all the little tumbler bits.

I have a sketch-up plan, but Erhan’s web site has some pretty good descriptions and stuff.

Now to try it with some nice wood.

Great little project. I know how nerve wracking it is to set the locks and combinations. If you do something wrong, it’s not so easy to fix!

Have your say...
