Category: Dapping Block

A doming block for raising curves out of flat sheet — start a disc in a shallow depression and work it through successively larger ones until the dome is smooth and even. Fourteen half-sphere depressions from 3.2 mm to 26.5 mm give a full graduated run for earring domes, pendant components and formed blanks; pair it with dapping punches and our guide to forming domes and beads.

The block is machined from hardened tool steel with the top ground flat, so the space between depressions doubles as a small flattening surface. At 125 x 65 x 25 mm and 900 g it sits solidly on the bench, and it is intended for soft, non-ferrous metals.

Elizabeth V. ★★★★★

The 14 depressions step up gradually enough that I can take a copper disc from a flat circle to a smooth dome without any hammer marks showing. Dapped a set of six earring blanks last night and every one came out even, no wrinkles. The hardened steel barely shows a scratch.

Kevin ★★★★★

I was worried the steel would be soft and deform, but this thing shrugged off a 2mm copper disc without a mark. The half-sphere sizes step up gradually enough that I got a smooth dome on my first try instead of a lumpy one.

Amelia ★★★★★

The 14 half-sphere depressions step down gradually enough that I can move a 1-inch copper disc from the shallowest curve to a full dome without any rippling. Hardened steel hasn't dented or marred after a few dozen hammering sessions. The 125 × 65 mm size sits flat on my bench vise without sliding a
