Full Description: *

A tamp pin fin is sometimes left around the blow tubes in the bath tub areas of the 823 S slab core. If the operator does not wipe this fin off the core, it may result in casting scrap. See attached file. Increase the diameter of the tamp pin in the bath tub areas of the 823 slab core, 4 places per serial, to reduce the fin created around the tamp pin. Make the tamp pins nylon tipped. Add a screen and drilled hole through the larger tamp pin to provide a path for gas to travel to cure the core. The tamp pin hole is .641" dia. Use a .625" dia nylon tamp pin. Reduce thickness of tamp pin fin created in 823 s core bath tub areas. Reduce damage and pattern shop cost to repair damaged core tooling due to core machine misalignment. Reference Temp. PPCR # PT6-12-58 & 79
