Graver = to engrave or etch depending on context – can it also be ‘carve’ as is currently translated eg. in Founders of small tin work (80v)?
searched for "grav"
translated relevant words as "engrave" or "etch" depending on context.
See entry p004v_3 (fols. 4v-5r) for an instance in which both are used, and "engraving" takes the sense of "carving" into the varnish ground covering an iron object.
On 80v (founders of small tin works), I changed "carve.. on stones" to "engrave," since the latter includes the sense of incising and also has a (now obsolete though related) sense of cutting into hard material (See OED "engrave" 2a). Other instances of "carve" became "engrave" or "etch"
