To make 2 Shock Mount Arms I squared up 1 blank on the Bridgeport Mill.
I did a layout with my CAD CAM system and drilled the pilot holes in the blank preparing the part to be Wire EDMed.
The CAD CAM system that I used to generate this shop print is the same system that will generate the NC code for the Wire EDM machine.
The blank is leveled out, picked up, and ready to be be cut.
This picture shows the tool path for the first opp on the screen of the Wire EDM machine.
This picture shows the finished first opp, nothing has actually been cut off the blank yet.
The next Wire EDM opp was done with the blank rotated 90 degrees. The first cut made the outside contour.
The second cut made the inside contour.
This picture shows a close up of the finished second opp, you can see the first opp profiles for both parts.
The third Wire EDM opp cut a 10 degree angled face on both parts making all surfaces of the parts EDM cut.
This picture shows the finished third opp.

Before I release the parts from the blank, I drilled the shock mount holes normal to the 10 degree surface cut in the last opp.
I used a boring head to put in the precision c'bores for the shoulder screws that hold the shocks inplace.
In this opp I release the two parts from the blank by setting the blank back up on the Wire EDM and cutting them free.
One is out, One to go. Now do you see what im doing? Cool huh!
Heres a close up of the two shock mount arms and the "slug".
I had to do one last Wire EDM opp on each piece individually because it could not be done in the blank.
This picture shows the blue light of the Electrical Discharge Machining on this last EDM opp.
This picture shows the finished last Wire EDM opp with the wire being threaded in the background.

To finish these parts they both needed two c'bores to contain the spring that allows the Shock Mount Arm to articulate.
This picture shows the finished c'bores.
There they are! The finished Shock Mount Arms.
