Hi KB,

I have the Lindsay book about pattern making and in all honesty it isn't very educational. I would suggest you try the varuious casting forums, do some reading and ask questions.

Here's a few links to get you started:

Patternmaking like machining are jobs you mainly learn by doing.AFS printed a "patternmakers manual ".This has the most general information that I am aware of in print.

As far as I know there is very little on this subject in print that is, step by step instructions for building match plates. If you can, conceptualize a picture in your mind of a positive and negative impression of the shape including cores and gating and risers you have a basic match plate. Take the shape in 3d and cut it at the inside surface line and you have it's match. The positive is in the cope and the negative in the drag sections of a mold. The idea is to cast both surfaces in one shot, on one plate without a parting line. Not easy to do but once you get the concept you'll have it for life. I worked for thirty five years as a Master Wood Pattern Maker. PM me if you require further assistance.
