Marvin,

I use a tub filled about 1/4 full of shavings, mix the BD into the shavings and give it a stir several times a day. I might let it sit for a couple of days prior to circulating it through more wood shavings attempting to drive off any methanol in solution. Once the soap has reduced to almost none, I send it through my resin columns and then final filter through 1 micron sock filter into 5 gallon containers. Some are using gravity feed and 55 gallon drums. Read the following threads and you should be able to come up with something.

There are plenty of other ones that are worthy of reading.

I don'k think anyone has come up with the best way yet. I guess what works for you is the best way.
