First read "Photosensitive Resists for Electroforming", T.R. Bates, Plating, July, 1965, published by the American Electroplaters Society, Orlando, Florida. Then see the Machining volume of the ASM Metals Handbook.

Save yourself a heaping pile of trouble!

Do not give in to the desire to do shortcuts. Adhere to your process. 99% of all problems can be traced back to someone not following the tried and true procedures. So many times I've listened to people complain of low yields just to hear them speak of how they "speeded up things"! They just don't get it.
