yeah man...

1. grind weed very finely
2. put weed in a Pyrex (or some easy container to pour from)
3. pour 91%+ isopropal alcohol in (just enough to cover weed)
4. let sit for 10 minutes or so (not a big deal how long)
5. pour it into another Pyrex that has cheese cloth over it (to filter out the solid plant material)
6. twist the cheese cloth like a bag around the plant material and squeeze all the alcohol out
7. now place the cheese cloth over the empty Pyrex with the plant material on it still
8. pour the alcohol back over the plant material again (to pull more resin off)

repeat steps 6 & 7 two or three more times

now let the Pyrex with alcohol in it sit to evaporate completely away. what is left stuck on the bottom of the Pyrex is your OIL...

you can boil the alcohol away which is quicker but it is mad dangerous too!

if you have more questions just ask... i did this quick cause i am mad stoned and got sick of typing... peace
