I create my patterns by wraping the dies with casting wax sheets. They give very good consistency on wall thickness. Depending on the mfrg and the particular box, the thickness can vary alittle so I have to order more than Ill use and measure the sheets rather than just grab n' go. Usually either 26 or 28 ga. gives a 3-3.5 mm casting. THE QUESTION: I do have a dip pot, but got quickly frustrated. Is this the predominant way of production, and what wax do you like? Ive seen many adds for different dips, and have heard that one quality-type guy uses a regular carving type inlay wax with good results.
