Try loading a plastic bottle with trim putting a coffe filter one end and runnin butane lighter gas throught it will come out as a golden liquid run that into a plexi bowl leave to evaporate you will be left with a beutifull oil once most has evaporated you can put the bowl in another bowl with hot water to purge remaining butane till it stops bubbling.
CAREFULL DO IT BEST OUTSIDE MAKE SURE THERE ARE NO SOURCES OF NAKED FLAME OR SPARKS VAPOURS ARE EXPLOSIVE
It makes a beutifull and extremely potent smoke but be carefull while doing I have scars from being silly like putting it on a boiling electric kettle butane honey oil BHO is what you end up with
Last time I was doing bubble hash I used a drill with a paint mixing attachment
Yeah I know what BHO is. I don't really dab too often though, so there's no point for me to go that far. But UD would make a hell lot of dab for sure, it'a difficult variety to process into hash. I started with bubble, cause dry sift never came out well. Trichs stick so much, that it's almost impossible to catch them without a solvent. This bubble is quite knarly though :)
I used to smear the oil on a paper and smoke it in joints as well as using bongs
