Are there three types of attachment on the Columbia Grafonola arms? I have seen a flat, springy metal piece screwed into the end of an arm and then there is the tab-and-slot version. I believe there is also one with a springy metal circlip-in-a-slot, correct?

Assuming that it does move freely and you are POSITIVE that it is the type with the wire retainer ring, first oil the joint as best you can. Let the oil run into the joint for a few minutes. I have a jig for holding the base, but you can wrap it with a thick towel or piece of thick rubber pad better yet and then secure it in a vice with just enough tension to hold it in place so it doesn't move. Don't over tighten the vice or you will crush the pot metal. Once securely held, swing the tone arm out and tap it away form the elbow (as to separate the parts) very gingerly with a small urethane or wood hammer as close to the elbow as possible. Every now and then I can simply oil them and they have enough play to wiggle loose by hand simply pulling outwardly and rocking the parts very lightly as you pull. But most of the time (like yesterday and last week) there isn't enough play to easily separate them, so I use the technique described above. If the elbow and tone arm are seized or exceedingly stubborn, be extremely careful and use as much penetrating oil as you can. Tap very lightly and take your time. I have never had one that could not be removed, but they do sometimes take a while to get apart. If you aren't sure if the parts have the inside retaining ring or the interlocking castings, the same technique will work, but with the latter configuration you want to make certain that you have the tone arm in the "raised" position (which allows the molded tab on the arm to align with the open slot on the elbow) should you need to tap it lightly. Otherwise, it will look like most of the elbows you see on eBay <frown>.
