Quarter-Sheet Sandpaper Cutting Jig
A slotted bench jig that cuts a standard 9 x 11 in (229 x 279 mm) sandpaper sheet into exact 1/2, 1/3 and 1/4 sheets for palm and orbital sanders: register the sheet against the 6 mm fence and run a utility blade down the 3 mm guide groove at 93.1 mm (thirds), 114.3 mm (4.5 in) or 139.7 mm (5.5 in) from the fence face. 154 x 100 x 15 mm open-frame plate with a perpendicular squaring fence, dot markings to identify each groove, and two 4.5 mm holes for #8 wood screws so it can be fixed to the bench.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
Five-Size Hand Tap Guide Block
A bench jig that holds a hand tap perpendicular to the work while you start the thread, with five guide towers bored 3.4 / 4.5 / 5.5 / 6.6 / 8.6 mm for M3, M4, M5, M6 and M8 taps. Each bore is 30 mm long (a ~9:1 guide ratio on M3) with a 2 mm funnel counterbore at the top; the 116 x 40 x 5 mm base sits flat on the workpiece and has four 5.5 mm holes for M5 clamp screws, and 1-to-5 tally grooves along the front edge mark which tower is which.
Brake Line Roller Straightener Block
A five-roller straightening block for 3/16 in (4.76 mm) brake, fuel and copper-nickel line: three 624 bearings on the lower row and two offset above squeeze the tube to a 4.2 mm nip (0.56 mm set) so coiled line pulls through dead straight. 110 x 44 x 18 mm body with V-groove entry and exit guides, 3.4 mm self-tapping holes for M4x16 socket-head screws (the 7 mm head clamps only the bearing's inner race), and four 5.5 mm M5 holes to bolt it to the bench — or grip the 9 mm plate edges in a vise.
Flagged: hydraulic brake system. Not for safety-critical use without independent engineering review.
