how long it tooks you to machine the last parts?
my cnc has a positionning speed of 4.2m/min and cutting of 1.5m/min but to get such result, it would take years anyway...
That was not done on my machine... It was done on one very simular, just larger.
That plug was roughed out with a 2 inch (50.8mm) cutter running 0.400" (10.16mm) depth of cut at 100 inch/min (2.45 m/min).
Then it was finished with a 1" ball endmill where the highest ridge was around 0.005" (0.127mm) witch sanded right out.
Each board of MDF wsa 9 layer thick and took about 2-4 hours. where the max length of the boards were 38".
There were about 8 boards total.
Lots of pic and a movie here

So.. If you have a 3D drawing and need a plug made, I think I can do it.
