This thread will contain general first hand knowledge of casting such as materials, methods, and techniques to get a workable model out of your molds.
People who don't know: Post questions.
People who know: Answer those questions.
Please be as clear and detailed as possible with your questions and/or answers. Repeated questions or variations of certain questions may be consolidated over time into an FAQ section in the post following this one.
Always ask and answer questions as if you were asking/answering your mother or grandmother. In other words, politely.
Rudeness and/or impatience will be met with an infraction. You don't want too many of those.
These threads are meant to reduce and hopefully eliminated the need for the numerous 'I need help threads' that seem to generate endlessly in this section of the forum.
They are not a be all, end all to all questions that could ever be asked though. Some questions will be project specific and you may need to ask those IN the project's thread itself. However, some may not see your questions there so you may post a link to said project thread in the appropriate "Help!" thread when you need the attention of a few extra eyes.
