Just a thought... have you tried putting your Q in the freezer for 15 minutes and then seeing if you can gently remove the cyclone bowl. i've never had mine stuck like your's but I would probably give that a try just in case it was an easy solution. i can't see where it would do any harm and it might work but if someone thinks it's risky I'm sure they will say something.
I had tried that a few times, and had no luck...stuck too tight...BUT, I just got really impatient, said screw it, and took apart the EQ. I was able to get the heater cover off of the heating element without damaging anything and my heater cover was fully intact. Once I got the heater cover with cyclone bowl still stuck, removed from the heating element, I stuck the heater cover/cyclone in the freezer for 15-20 minutes. While they were in there I searched FC for un-sticking GONG joints...I found a random thread, non EQ related, that had a quote from TokeCity. The quoted person had spoke with Illadelph and was told that tapping on the gong joint with a wooden spoon would help...
So after I removed the cyclone bowl/heater cover from the freezer, I tried twisting/rocking gently and pulling, with no results. Then I took a wooden spoon, and tapped around the gong joint for about a minute or two. I gave a twist and it snapped free! I got the cyclone removed from the heater cover, without damaging either of them! I put the heater cover back on the heating element, and reassembled the EQ. Once I got to the point of connecting the LCD/control panel and the power cable, I turned it on to confirm it was making heat, before putting it together any further.
I'm so happy I got impatient enough to just go for it, and that it worked! I vaped a nice bowl of AK-47, packed in the elbow screen, sat in the downstem of the bong, with the q held gently in the down stem Cloud style!
Got some tasty whip-free hits between 165C and 195C.
Thanks again Photobooth for posting that video!
