Hello Sparkplug549:
The Moonraker Hubs where a cheaply made Cast Aluminum, that even broke when tightening when brand new ones out of the box. I know I broke a bunch of them while trying to be careful while tightening them or compressing them down on the Boom.
New Hubs could be made on a CNC type Mill, but you would have to pay for set up time, material, and labor. The cost of all this could possibility be recovered if more hubs where made and sold.
New Technologies in the Casting World, can add certain addatives that will allow the aluminum to be significantly more resilient allowing the Hubs to be compressed and not break. But the tooling cost will be around $1500.oo dollars.
I have had Hubs made, but for a stronger larger Boom diameter of 2 inches. The Moonraker 4 Hubs are for 1 5/8 and the Moonraker 6 Hubs are 1 3/4 inch Boom Diameter.
These Hubs are made from solid or billet 6061-T6 Aluminum Material, and use a 3/8 SAE type bolt to compress against the Boom. And have been tested to be almost fully closed, and then opened many times over and do not have the breaking problem as do the Moonraker Cast Aluminum Hubs.
If you replaced the Moonraker Boom and Hubs, you would have a bullet proof upgrade there. But the cost may out weight the cost of a new antenna.
Here is the link to my hubs

These Hubs where made for the "Typhoon" type Beam Antenna that uses a quad reflector and driven element, and yagi type directors. That is still being designed and built.
