Maybe I should just get a diamond cutting blade for my Dremel and see what happens..... I mean, the bulbs are already dead...
Hello,
Thats a good idea, you need small dreml cutter wich are diamond coated in the design similar to a small cuttoff disc. Then you remove the lamp base. If you do not want to destroy it mecanicly you can heat it up, and the cement should loos it glueing properties. As next you brake away the sealing nipple and cut of the wires leadin in the stemm. Now you put your cutting disc on it, in a way that the screw wich fastens it to the dreml shaft is in the stem cavity. You grind with the surface of the disc slowly the stem out, wich can then be extraxted in one piece. So unlike with angle grinder you do not cut with far edge of the tool but with its side. Cutting it with the tools edge will likely destroy the glas. Water cooling(By a wet brush for example), and only light pressure.
Another method is, you start with a class cutter and score a line around the lamp, then you put a piece of adequately seized iron wire around it (1 loop) wich is then connected to an adequate source of electricity. The wire will start glowing and make a clear brake-line along the scared line. The correct wire size and electricity sources must be found out by experiment, as i do not recall what i did use. I used that method for opening christmal light bulbs, to convert the to led. Note, here a agin it is essential that the vacuum is removed before opening the lamp.
Best regards
