Bookbinding cradle and piercing guide — PierceVale | JLF-237

COLOR: BLACK. The supplied print is black; render colors are illustrative. Support a folded paper signature while marking five sewing holes. An integral V cradle avoids interlocking loose supports; a removable guide registers at one end and can be lifted away. DIMENSIONS 88 × 188 mm base; 90° V; 149.6 mm guide; five Ø3.2 mm guide holes at 30 mm pitch. Pocket signatures up to 150 mm along the fold. CONTENTS 2 printed pieces: 1 × cradle, 1 × five-hole-guide. Material: PLA. SUPPLY SEPARATELY Folded paper, a slender bookbinding awl, thread for later sewing and a thick sacrificial work pad. USE AND ASSEMBLY Print both parts flat as supplied. Turn the triangular guide point down. Place the folded signature in the V, register its end at the low end fence, then place the guide in the fold with its end touching the same fence. Hold it lightly; it is removable, not latched. Mark/pierce through the five holes with a suitable awl. The centre underside is open: work on a thick sacrificial pad, keeping hands out of the tool path. Stop if the awl binds or the guide deforms. Guide height varies with paper thickness; do not force it down. Images are renders of the actual CAD. Geometry and reference slicing checked digitally; physical fit, finish and service life have not been established by those checks. Printed to order. Shipping and taxes are calculated at checkout.
