INEXPENSIVE, REUSABLE TEST MATERIAL Machinable wax seemed like a good idea..until I saw the price. After browsing the web, homemade machinable wax sounded like a possibility. After reading the recipes and recovery procedure of the machined waste, I was scared off by the severe burn danger of the learning curve. My aim is an inexpensive, recoverable, machinable material to practice on. Soby ALLEN520 - Handibot Forum
