Naw... I took one of mine completly apart once. Just to see if I could do it.
To change the glass, you unscrew just one thing and screw it back on with the glass or metal ring.
To fill, you close the bottom which has the air holes, then take off just the top part your mouthpiece sits in.
To rebuild, you unscrew the bottom part and lift it out, then there is just the ring around the wick.
Easy to rebuild.
Basically, unless you really WANT to, you only have a total of 4 things to worry about screwing on and off.
Mostly, I just use the top to fill, and the bottom to rebuild.
