Radial Lead Five-Pitch Forming Jig
This bench jig has five forming blades for bending the leads of radial parts like LEDs, electrolytic capacitors and TO-92 transistors. It spreads the 2.54 mm factory lead spacing to 3.5, 5.08, 7.62, 10.16 or 12.7 mm (perfboard 2-5 hole pitch). Each blade is the target pitch minus 0.6 mm wide, which leaves room for the lead itself. You press the part down over the chamfered blade top, and the leads end up parallel and spaced right. The 10 mm blade height plus the deck gives every lead the same trim length. The base is 90 x 44 mm and the jig is 14 mm tall overall.
18650 4x5 Spot-Weld Grid Jig
A 20-cell spot-welding jig for building battery packs (for example 4S5P or 5S4P) from 18650 cells (18.4 x 65 mm). The 18.9 mm pockets sit on a 20.5 mm pitch with 1.6 mm webs, so the cells stand square and evenly spaced. The jig is 108 x 104 x 14 mm. A 14 mm hole in each pocket floor lets you push the cells out. A side ledge has an end stop and cut grooves at 20.5 mm steps, so every nickel strip comes out the same length. Print two, one to cap each end of the pack.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Universal Toroid Winding Cradle
A bench cradle with a tapered double-V pocket. It holds a toroid or ferrite core upright while you wind it. The pocket narrows from 18 mm at the top to 3 mm at the floor, so it wedges cores about 3–18 mm thick, and the 36° end ramps centre any OD from a T-50 (12.7 mm) up to an FT-240 (61 mm). The winding hole stays clear above the 28 mm tall jaws. It also has a 1.5 mm slit to hold the wire tail, and the 110 x 50 mm base takes two M4 or #8 screws through 4.5 mm holes on a 94 mm pitch.
Hinged SMD Stencil Paste Jig
A print-in-place hinged jig for applying solder paste through an SMD stencil: the 95 x 80 mm base deck has a 70 x 50 mm pocket 1.6 mm deep that holds a standard FR4 board flush with the deck, and a 95 x 62 mm frame folds over on a 5 mm print-in-place hinge so the stencil stays registered while you squeegee. Two 11 mm ejection holes push the finished board out from below, and two M3 clearance holes tie the jig down to the bench.
Axial Lead Bending Pitch Jig
A 136 x 26 x 14 mm bench jig for forming the leads of axial through-hole parts (1/4 W resistors, diodes, small caps) to exact PCB hole pitch: lay the body across a rib, press both leads down the sides, and the lead centres land on the 2.54 mm grid. Six ribs give 5.08, 7.62, 10.16, 12.7, 15.24 and 20.32 mm (0.2–0.8 in) pitches — each rib is milled 0.6 mm under its pitch so the bent lead diameter makes up the difference — with 3 mm relief slots through the 4 mm base so long leads pass clear, and two M3 clearance holes 122 mm apart for bolting it to the bench.
18650 Four-Cell Pack Jig
A 44 mm square block with four through-bores (18.7 mm, on 20.6 mm centres) that holds four 18650 cells upright, parallel and bottom-flush against the bench so nickel strip lands square during spot-welding or pack glue-up. Open-topped grab notches — one per cell, in 4-fold symmetry — let you spin a cell to set polarity, and two 5 mm ears with M3 clearance holes bolt the jig to the bench; overall 68 x 44 x 26 mm.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
