Thanks for the compliments Erazz.

I used MDF as it is very cheap to experiment with, also my spindle is a fixed rpm version and too fast for dealing with metal!!

I will try the resin method, although I will have a go at using polyester as I still have a few kilos of it (about 10kg). If it works out, that's great. If not I will have wasted a few hours and others can learn from my mistake.

My software does not allow pocket maching in 3D it will only give the option of X-Axis, Y-Axis or at an angle of 135 degrees. It does allow the option of another pass at 90 degrees to the first though.

I can't easily re-machine the mould surface, but I will have go at another one, this time with an 8mm ball nose (that will allow me to drill the locating holes at the same time.

I have already redesigned, and cut out new Z-axis parts for my CNC machine, I'm just waiting for the trapezoidal nuts to arrive. That should sort out some of the roughness, and a smaller stepover should also help. Thanks for that info, by the way.

Just one question. Do you have any idea how well the cutter handles the resin coated MDF?
