get yourself a grinder with a keef catcher or a fine screen and a hash press. Grind your buds or leaves until they are as fine as you can get them then gentle push the matter around on the screen until enough tricomes have collected under the screen for you to fill up about an inch of the hash press. (you can still smoke the ganj) Screw the hash press shut and press the hell out of it. You can even put the hash press in the oven for 10 minutes and then give it a few more turns to compress your product alittle more.
It might not give you a huge quantity, but i made some from local outdoor and I might just say that its better than any Afghani, Dutch, or Polinesian hash Ive ever smoked.
