| description | Worn interior wall surfaces of a sand casting flask cope or drag frame are resurfaced by covering the surfaces with thin, metal liner plates. The liner plates are bolted to the flask walls by bolts that extend through bolt holes in the liner plates and walls. The bolt holes through the plates are provided with deep countersinks for receiving the bolt heads and spacing the bolt heads beneath the exposed inner faces of the plates. Molten weld material is applied in such spaces for welding the bolts to the plates. A thin, hard coating of metal, such as chrome plating, is applied over the liner plate inner face and exposed weld material at the countersinks. Thereafter, the liner plate is removably fastened upon the inner surfaces of the flask frame by extending the bolts through the bolt holes in the frame wall and securing them in place with suitable nuts. |
