does anyone know were to get large blocks of green carving wax. I
am looking for 80mm square x 6+ inches long.
I don't know if it's green or not, but MSC (mscdirect.com) has a
product called 'machinable wax' in many sizes, both as blocks &
cylinders. It's located on page 1744 of their 2006-2007 catalog. One
item # is 00263343.
