I think you might be refering to me for the 3 color hand pour. I do it with a pyrex 4 cup. The divider is a one piece folded into a "V" and JB welded into the cup. The center section is about 1/2 the volume of the others. If I remember correctly I posted a pic of the cup in the gallery.
I just checked the gallery. The pics of the baits are there but the pic of the cup is not; along with most of my pics. Don't know what happened but maybe one of the Admins can help.
