That number is the number I set the thickness dial at. Then take that new modified CT and subtract it from the thickness of the lens blank. Take the job ticket's CT and add 2.4mm to that.

Layout lens, tape it, then measure the thickness and note it. I will explain this and then ask a few questions: Here is the process I am instructed to do. Thank you so much for any and all that can help me out a little. and searching the internet has little results other than a few people that are advertising theirs for sale. So I need to know everything about the 108 generator and the different configurations of this model. they say that is how we were taught many years ago and we just know it works. also when I ask questions, they tell me that they don't know why things have to be done this way. There are some weird things I am instructed to do and do not completely understand why I have to do these things. I guess I am just looking for some 101 pointers and hopefully some links to basic instructions of how to use the 108 generator. I then position the wheel and move the stock into the wheel until the tip of that attachment touches the wheel. the 108 I am using today has this weird attachment that I place on the stock and over the lens. To set the thickness on my old generator I had this lever that moved the stock. The generator is also different in itself.

The process in calculating the thickness is different. The 108 I use now at my new company is set up totally different than my old 108 at Lenscrafters. I was wondering if anyone has any information on the 108 generator.
