Gearmotor Antenna - Making Parts
In this photo, you can see the adapter that I machined from 6061 T6 aluminum, and joins the upper and lower mast sections into one assembly.
The tube for the lower section of the mast is seamless 304 stainless steel with a .062in wall.
The upper section of the mast assembly is seamless 6061 T6 aluminum tubing with a wall of .062in and once I had the machine work done, I then had the tube chromed.
When completed, all of the external SS parts of the antenna other than the chromed upper housing, will have a high polished finish.
