Its new VFD time!

Since our first Huanyang VFD (variable frequency drive) packed it in, we had been running our 300W Ryobi trimming router. 

So we finally got our act together an ordered a new OMORN VFD.  The first cutting job was some 3D profiling of MDF to make my first CNC routed mould for composite parts.



Hacking into the chuck of MDF router a 6mm single flute end mill.  Followed by an 6mm ball mill for shaping,

The MDF was treated with 3 coats of epoxy.  Then sanded back to a surprisingly smooth surface finish.  I was very happy with the quality of the mould surface.

I then packed the part up in the mould by 3mm and ran a trace program with a 3.2mm carbide burr to cut out the part.


This finished part is a gooseneck fitting with mounts for lower stays on the one bracket.  This will be used on the sailing boat I built several years ago.
