Those parts are like arts, guess that with a CNC machine , you still have to put in hour of design of the part in CAD program. Best is that it can be reproduced from files if needed. Have not had any chance yet to test CNC milling but do a lot with laser cut with very good results from CAD drawings.
Hours, weeks or years, who counts but I couldn´t resist to ask, that´s no 1 question when showing the models, my model was started also 8 years ago but there has been some time without anything happening.

I don't save my CAM files too often because I machine things most of the time "one off" and to do fancy setups with all the tool changing would take too long. I do save the drawing files and if I need to make a second one in the future I just click the lines I want to machine and then generate a CAM file. Most of the time I just use the mill manually.

Now for the fairlead sheaves..








I used the same fixture for all three different size sheaves


Almost finished


Hollowed out are for side sheave clearance.

Boring the wheel for bearing






Almost ready to cut loose.


Drilling the mounting holes for the guards that protect the wheels from the crows foot
jamming back into them. I still need to figure out how to machine them.
