SWIM's so excited!  He's getting a dehydrator like ron's (excalibur 2400).  This will really speed up the process for him and he guesses that he will be able to distinguish between higher and lower purity portions of the extract.  Would such a device be safe to use when making the HCl form, as well?  Or would corrosion be an issue with this?

SWIM also got a hold of a little glacial acetic acid.  Has anyone tried precipitating directly out of limonene with this?

Also, SWIM's last yield was about 430mg, but he suspects that the impurities increase with every successive pull, whatever they may be.  Or else SWIM's just gotten too used to the effects and simply needs to find his high threshold.  Moisture contamination may also be an issue...SWIM will know for sure after he gets his delivery.
