Mold Wipers
There are two felt wipers which are designed to keep the face and back of the mold clean. A small amount of a mixture of cup grease and graphite rubbed into the back wiper will keep the base of the mold clean. For the front mold wiper, keep the felt well saturated with graphite. Do not use oil or grease on the front wiper, or it will be transferred onto the matrices and into the magazine. A good plan is to soak the felt with gasoline and rub the graphite in. When the felt becomes worn, new ones should be applied. When applying new felt, put graphite between the layers. Be careful that the felt does not become worn to the extent that the steel part of the wipers will be allowed to rub against the mold.
