RK05 pack (not drive!) conversion

Hi folks, I'm currently sorting parts of my stuff. And I found out that I have less RK05 packs with 16 sectors (PDP8) than drives. I have some 12 slot packs as well. But I could need more 16 sector packs. I have access to some masses of 12 sector packs... Probably I'm not alone with that situation. If there's enough interest it could be possible to machine new center hubs for the packs. With custom sectoring. I'm quite sure that the biggest part of the cost would be the programming and setup of the CNC that turns the hubs. Then changing the sectoring to customer demands will probably cheap and easy. So the idea of making new center hubs could be quite interesting for the folks who need the same pack style for other computers with other sectoring. I know of IBM 1130 and some HP computers using the same packs which were originally an IBM idea. Any comments? Interested? Your feedback helps me to decide if it's reasonable to do it or better put the idea into the trash. An important point would be the amount of cash one is willing to pay for one center hub. Kind regards Philipp --
