The Bee Works has the best instructional videos I have seen in many years.
Their video "Queen Rearing" covers all aspects. It describes equipemnt available, queen marking methods, making nucs, no graft queen rearing, nicot system, and grafting. It is available in VHS and DVD formats for $25.http://www.beeworks.com/uscatalog/details/queen_rearVID.asp
I used their video "The Nicot System Demonstrated" to develop my timeline.
The "Queen Rearing" video uses the same video that the "Nicot System Demonstrated" uses, so there is no need to purchase both.http://www.beeworks.com/uscatalog/details/nicotvideo.asp
These are the steps I used for using the Nicot System:http://nordykebeefarm.com/forum/forum_topics.asp?FID=6
