Hello Wolfie,

Good job on this first project.

I’ve tweaked a bit your project here are the points that I’ve modified:

– as your using 16mm boards 8mm dowels are a bit big so I’ve changed them to 6mm. 

– your back can’t be fixed so I’ve made it rebate into the sides, top and bottom. this way you can assemble the carcase and pin it. This will keep the whole cabinet square. Note that the rebate in the top and bottom must be stopped before the end of the board so as not to show up on the out side of the casing, you can be do this using a router or circular saw. 

– I’ve added some parts to the plinth so that you can assemble it as a frame. You can either just put the cabinet on it or screw through from the under side. The inner parts are dowelled but outer corners are mitred to give a better aspect. To assemble the mitres I’d suggest just gluing and pinning a block behind, much easier than trying to dowel.

Hope this is OK with you.

Here are your plans.

All the best,

Ness
