Well my FOAF is using powdered bark and this tek which they actually had good results with despite its simplicity, the tek is as follows. The FOAF are not extracting the naptha as said in this guide they are using a glass baster.
thanks,

A simple 1/2 lb MHRB TEK
--------------------------------------------------------------------------------
I've ripped a lot of this off from other teks, but this is simple:
1) Equipment needed-
1 gallon plastic jug (the kind white vinegar comes in)
plastic or glass funnel
pyrex baking dish
1/2 lb MHRB
1/2 lb NaOH
3/4 gallon water(tap works fine)
1quart VM&P NAPHTHA
2) The process:
a) Place the funnel into the clean, dry jug
b) Add the NaOH
c) Carefully fill the jug up to 3/4 full with water
d) cap the jug and invert to dissolve the NaOH, venting the cap after
each inversion.
e) Set the jug into a pot of cold water to dissipate the heat generated by the reaction of the NaOH and water.
f)Put the funnel back into the jug and add 1/2lb MHRB powder.
g) cap the jug and invert to mix thoroughly.
H) funnel back into jug, add apint of NAPHTHA, cap thje jug and invert slowly several times.
i) Let the jug sit for an hour, invert several more times.
j) repeat step i one or two more times, finally allow NAPHTHA to separate from the basified sludge.
K) Set the jug inside the pyrex dish. Using a sharp implement, poke a hole in the jug just above the NAPHTHA/sludge interface, and allow the NAPHTHA to drain out slowly into the dish. When done draining, dry the outside of the jug and place a piece of electrical tape over the hole you poked in the jug.
l) put your baking dish in front of a fan and evaporate the NAPHTHA, you will have quite a bit of pretty DMT crystals in the dish when done.
m) Fill that jug with another pint of NAPHTHA and repeat steps i-l.
n) wash those crystals with ice cold water if necessary(I have never needed to do this)
o) I have been getting about five grams from 1/2 lb MHRB.
*I warm my NAPHTHA by placing the can of NAPHTHA uner a stream of hot water in the sink for five minutes, I think recovery is higher with warm NAPHTHA.
I like this recipe because it eliminates the need for a separatory funnel, no acidification necessary, and I end up with a pretty clean product in the end.
**have fun, be safe-AND FOR GOD'S SAKE_WEAR EYE PROTECTION AND GLOVES WHEN WORKING WITH NaOH!!!!!!!!!!!!!!!!!!!!!!!!!!!
