lewd taught me
There is already a site that had directions and another one with pics. email me if you are interested in the one with directions. I used both. The one with pics:

These are tips I picked up from LIBeef, my own experiments, and other lab scientists:
This will be updated and organized every 2 weeks or so.
1. This takes about 3 days to complete if you have things to do. It is possible to start it on a friday morning and be done Sunday night or Monday morning. If you have someone that will be upset to see you experiment, don't do this at that location.
2.skip the reading step where you make Test crystals. It is difficult to get long crystal to seperate the Test from the salt. I completely skip this step and put everything into vial #3. I heat it up and let all of the fillers and binders settle at the bottom for 24 hours before drawing AS from the top of the solution for filtering.
3. get 2 extra filters. clogged filters suck.
4. I was doing my conversion at 3am and ran out of GAS LINE ANTIFREEZE. I was getting mine at a hardware store and the 24 hour convenience store did not carry it. I went to a gas station and found some there.Probably will only find it there in the winter time.
5. best place to put the solution for evaporation is someplace where there is warm air circulating like at the top shelf in the kitchen.Use a fan to let the air above it circulate.
6 when filtering you want the solution to be hot, about 200deg.use a candy thermometer in boiling water to check that the temperature is 200deg. generally boiling water is 200 deg after a few minutes and does not rise above that without pressure. Do not go to 250deg as that is the temperature that filters will fail. place the vial in there(not over the heat) without the top for 5 minutes.
7 I use 5ml syringes when filtering synovex now. be gentle as you put a lot of pressure on the filter with little effort.Only just enough effort to get a steady stream.puching hard will not make it run faster.
from whatman filters web site:
As a general guide, the following pressures can be obtained by hand with the syringes indicated: 20ml, 30 psi; 10ml, 50 psi; 5ml, 75 psi; 3ml, 100 psi; 1ml, 150 psi.
