Therein lies the rub. Yes, I absolutely HAD to use a masonry bit, along with using the "hammer" setting on the drill. I believe I piloted a hole with a sharp metal bit on the inner metal sections, and tried to remove as much of that stuff as I could, You only get so far with that. The metal twists and gets mixed in with the "concrete". (I say concrete, because I think it was). Then you crack out the 'ol mason bit, then you have a go at that. You only get so far there, because of the metal dulling out the mason bit. Then you put it on hammer mode, and then gently give it a whirl. You only go so far again. Then it's back to the metal bit, which gets dulled out by the concrete. rinse, lather, repeat. Make sure you have plenty of drill bits and lots of "mettle" on hand. Oh and specific gloves soas you can feel the pressures exerted. Haven't found an effective way to really clamp it without harming the cardboard tube, so holding (for me, anyway) is best. Some seemed slightly less difficult to gut than others, but you have to take great care, as the muck runs all the way through it, and once you get about half-way, it can get pretty intense, as the tube can start becoming *thinish*, as sometimes the concrete is a little stuck to the inside wall. Yeah, I've run across a few like this, especially in Zeniths, and also in a 1936 Mills jukebox, to be precise. Good luck to you, should you choose to accept this challenge!
