Smitty, I know you are interested in these type chips. I only wonder why you don't check my site more often. Since I tried to incorporate all info from Kregg's book on my site and have added much more it would seem to be a logical move.
For example, if I found an interesting mold design, before asking about it on the board I would check Robert Eisenstadt's site.

I wouldn't say this to most, but I consider you to be "crest & seal" savy and would know what sources to check.
