Who is ready to build a soap box? No, not to stand on, but to pour home made soap into!
Okay, they are probably more technically a soap mould, and much better than getting on ones soap box.
Pretty basic design. I used 13mm (1/2 inch) ply off cuts. My friend David then brought around his Triton workbench with electric saw attached and we cut up the ply into the right sizes. Nice and straight cuts.
You can see the big stack of individual sections next to my tool boxes. I took the measurements from a wooden 1 kg (2.2 lbs) soap mould, and basically copied it. It was very easy to construct after all of the pieces were cut, and I was amazed at the simplicity of the design. Just one long length of plywood, 89 mm (3½ inches) wide then cut into various and screwed and glued together.
The bottom of the mould had to be sanded individually for each of the boxes. Usually I only need to trim off a millimetre here and there, so that it would fit snugly.
Once I got the bottom to fit, I screwed on some legs to make it easier to put on and off.
