Well... if you make green dragon, adding one more step is all you need to make hash oil. When the green dragon were ready, just evaporate all the alcohol of it (i use an water bath to do it). When all the alcohol evaporate, there will remain a dark oily sticky thing, which is the hash oil.

Anyway, look at this recipe, cause there is a lot of other useful informations there, like how to scrape it, how to smoke it, etc...
