I would be interested in knowing what size cell cups you use? The ones that I have made are a little over 5/16".I got the idea from fatbeeman's video on making your own cell cups. I looked at some of the cell cups made buy the bees and they look small compared to say 3/8".Here is a pic of the cell bar and cell cups I have made so far.
