Tonight I spent a few hours (nothing is ever quick when it comes to CAD assemblies with interdependent pieces) doing some final tweaks on the design and preparing it for cutting. If all goes according to plan I will be cutting the pieces tomorrow night, then things will really start to take shape!

Once I have proved that the design goes together nicely, I will share the DXF files for anyone who is interested.

They have been laid out to fit on a 1200x600mm piece of 3mm plywood.

This design is actually far better suited to laser cutting, what with all the tight inside diameters, but I have a generous friend who will do it on his CNC router for the price of takeaways, so I'm going to give that a shot first.
