Finally got a chance to put the CNC router to work. The first image is a trial run of a goose-neck fitting mould to be made from MDF.
Below is the MDF mould after roughing out with a end mill.
After finishing passes with a 8mm ball mill.
Single coat of epoxy resin prior to sanding. Note: A single heavy voat of resin was sufficient. The surface sanding back to a very nice mould surface. I was certainly impressed.
The component after vacuum bagging.
I used the router to cut a slot for a standard stainless steel Reilly fitting. This was test fitting the depth of the slot.
Using a trace function to cut the profile of the part in the mould. I used small spacers of 3mm Perspex to keep the tool away from the mould surface.
Test fit on the mast :)
The cavity between the mast and fitting will be filled with Q-cells to improve the compressive strength (Vang loads).
