steiner666" said:But the air doesnt come up from the lower part of the unit, it comes in through those holes along the top of the cap" True and false. The majority of the air DOES come through those holes, but air is still coming up through the unit. if you blow through the bottom of your solo, in the holes around the power jack, you can clearly feel the air coming out the top (try it with the solo on max temp to more easily feel the heated air being blown out the top) - thanks to mattyg23 for pointing this one out.
The airflow is from the outside, through the small holes in the top cap (around the outside circumference), into the housing, through the top just outside of the crucible and in up through the holes in the crucible. no air (or virtually no air) flows otherwise. If you look at my post here somewhere in the middle are pics of the crucible housing taken apart. this is of the ceramic but the SS is the same. you can see that the crucible sits inside the plastic housing, offset with some standoffs that keep the crucible wall about 2mm from the plastic wall. these form the airflow channels from the top down through the crucible holes. you can see all 4 holes have an associated channel and are isolated from air getting in any other way.
However, the top area is not air tight from the rest of the unit so its possible that air from the body can get into the head and into the airflow. i suppose one could block off the areas around the head with cotton to prevent air from flowing other than through the top.
steiner666" said:So logically this would mean that when you are inhaling with the cap on, the airflow is more restricted so theres more of a chance some would take the (admittedly, more restricted, but still present) airpath up from the bottom of the unit, making it flow over the electronics/battery areas, which i still think are what the smell/taste come from. The cap would also probably trap any fumes, or whatever causes this, when its on versus it being off.
I think it would very minimal because there would not be enough suction to over-whelm the airflow through the top cap. Although I haven't tried it my recommendation would be to do the ring mod in my post above, then pack cotton around the head trying to leave a bit of space at the top. the idea is to restrict airflow except around the top of the crucible, if you were really concerned about air getting in any other way.
steiner666" said:What i DID try however, was rubbing the cap down with a paper towel with a tiny dab of iso on it. I was surprised when i looked at the paper towel after whiping the inside of the cap when i saw a blueish/greyish residue left behind on the paper towel. I wiped the rest of the inside, as well as the outside down and got a little bit more from both sides. Curious, i wiped the rest of the unit and got black residue, wiped it again and got more. Related to the source of the stink/taste or not i dont know. But i took a qtip and swabbed the inside of the housing thats down around the part under where the cap threads on, around the heating element, and, sure enough, i got more bluish/grey shit.
Well, its just paint of some sort. maybe some kind of epoxy based paint. i don't know enough about industrial finishing to know what you use. but you could have totally cured paint and then apply a solvent like iso and it will dissolve, that doesn't mean its bad or otherwise getting into your system. they could have anodized the case but that would have been added cost which would have translated into a more expensive product. i am sure they weighed the pros and cons and picked what they thought was the best finish. it might be a problem to some people, but not all and was likely inexpensive enough too. its hard to make a product that is going to satisfy everyone.

If you look at my post above you will get a sense of how far you can disassemble without getting into major surgery. the only part i'd like to dig in more is the crucible and heater. its sealed with a high temp cement and the only way in would be to break that. so i didn't.
If you take it apart to the extend I did you can see there are a lot of opportunities to open up and guide the airflow path so that air is only sucked in around the bowl when its inserted, down through the channels and up through the crucible holes. i am not sensitive enough to the smell to bother doing this and testing it. but if someone who is sensitive to the smell can do the modifications and report that would be useful.
