Oh, those CAN be hollowed out. Have done several, including a few in the '36 jukebox that I rejuvenated not too awful long ago. It takes ALOT of time, drill bits, sweat, gloves, consternation and determination to make it happen. Yes. Yes, they can be hollowed out while saving the shell. If I recollect, a Zenith I did awhile back had what looked to be CONCRETE in it. It was that hard. But I got it all out, and the tube looked none the worse for wear.
