The wiki contains all the extraction info you need. Also, you said you don't want to use lye, the Tek you linked to is a lye Tek. That Tek also suggests usin ammonia to do a wash. This I would recommend against as it has led to significant loss in yield.
Why don't you post an introductory essay so we can get to know you better? I would suggest to do some reading in the FAQ and WIKI before posting any questions as most answers can be found there.
