Cutting the final stood from plywood using the CNC router:
Gluing the pieces together:
Added small pieces of MDF under the clamps to ensure the pressure was evenly spread out, otherwise it could cause the pieces to tilt slightly and make the legs uneven.
Spaces (see images of joining above) from the CNC router make it wobble slightly, a tighter fit means less movement. This wasn't noticeable on the smaller model, but evident on a larger scale. Could hand cut these in future to ensure a tighter fit.
A bigger shoulder could be added around the mortise and tenon joints = more area to therefore give more stability and longevity as a stool.
If had made of real wood, could have cut into the mortise and tenon joins and hammered in a wedge to expand the wood and secure - easy to repair also. Could either saw the excess wood off or put a peg through the extended wood - can theoretically disassemble.
To do now: consider how to finish the surface of the wood
