Good job on the oil ive been making it just like u said except for a couple exceptions... Heres how i do it....

#1- throw 99% alcohol and clippings(i use more bud than shake but its expensive...yet way worth it) into the freezer to chill for 20 mins
#2- While waiting take a CLEAN 2litre pop bottle and cut the top off it where the bottle stops curving
#3- After 20 mins take alcohol and clippings out... Place the top portion of the bottle upside down(opposite as it was as normal) and take 1 piece of silk/coffee filter whatever u want that will strain ur clippings and place in the upside down top section
#4- Take just enough clippings and place them ontop of the filter in the top...
#5- Slowly!!!!! Slowly pour ur alcohol over the clippings until they are overed and just under all the alcohol...It now will just drip into the inside of the big portion f the bottle for collection...
#6- As soon as the drips from the top have stopped i repeat step #5 three times (or even less if the green starts soaking in) with the same alcohol that was used the first time...
#7- Take the collected and tastey golden color alcohol and boil as said by Harddon basically the same way as Harddon said from here on... I boil on #2 on my little stove so itdoes not need to be hot at all

A good tip when finising when it wont light up in ur face HAHA dont do this till u have made this a couple times and have some clue when its done!!!!!! please no flame near it until u have some clue!!! I also just leave my oil in the pyrex dish i use upside down so stuff does not fall in it.... i dont think i can do this the 24hr way itll drip
